    Dawn of a new extreme sport: The world's first electric wingsuit

    Austria's Peter Salzmann powers through the air in his 300-km/h,
    twin-impeller electric wingsuitBMW

    Wingsuit flying certainly captured folks' attention when it first hit
    the mainstream around the turn of the millennium, sparking a wave of
    GoPro and Red Bull videos. Human flight had never been so personal or
    so physical as these intrepid maniacs half-fell, half glided through
    rocky gaps and mountain passes like turbocharged flying squirrels.

    The name of the game quickly became to see how close you could fly to
    things without hitting them, in search of the ultimate rush and the
    biggest view counts. But these devices were limited in that your only
    source of acceleration was gravity itself, and your flight profile
    could only ever take you downward.

    No longer. Stuntman Peter Salzmann had been thinking for years about
    how to add some sustainable propulsion and climbing ability to the
    wingsuit experience, and he hooked up with creative consultants at
    BMW's Designworks studio to create a chest-mounted set of electric
    impellers and a wingsuit that would work with them.

    At first, he wanted to mount the props in a backpack arrangement, in
    longer tubes capable of generating more thrust. But the most
    advantageous airflow would be in front of him, and he found the
    initial design too heavy. So a chest mounted system it was, with two
    5-inch (13-cm), 25,000 rpm impellers in a relatively compact but still
    pretty chunky unit that has a bit of a submarine kind of look to it.

    The wingsuit was designed to incorporate air inlets for the propulsion
    system. There's an on/off switch, a two-finger throttle and a kind of
    steering facility, as well as a cutoff switch for emergencies.
    Otherwise, she's even more of a physical thing to fly than a regular
    wingsuit; you need plenty of core and limb strength to fight the wind
    and control your motion in the air.

    The project was done in partnership with BMW's Designworks studio, as
    a promotion for BMW's electric iX3BMW

    The props put out a relatively modest combined 15 kW (20 hp) for
    around five minutes, but the results are pretty epic; a regular
    wingsuit's most horizontal glide ratio drops around a meter for every
    three meters traveled horizontally, and speed tops out around 100 km/h
    (62 mph), but when Salzmann hits the electric boost, he can hit speeds
    over 300 km/h (186 mph), and actually gain altitude to fly upwards
    instead of constantly dropping.

    After wind tunnel testing, both in BMW's more auto-focused facilities
    and in a specialized wingsuiting wind tunnel in Stockholm, and around
    30 test jumps, it was time for a public demonstration. The initial
    plan was to demonstrate the suit's climbing capability by taking it to
    Busan, Korea, and flying over a group of three skyscrapers, in which
    the final one was much higher than the first two.

    COVID-19 put paid to that aspiration, so Salzmann settled for
    something prettier and closer to home, lining up the Del Brüder peaks
    in the Hohe Tauern mountain range, part of the Austrian alps. Salzmann
    and a pair of buddies kitted out with regular wingsuits went up to
    10,000 feet (3,050 m) in a chopper, counted down, and jumped.

    The others are there to act as a reference point, and the three hold
    formation until Salzmann hits the juice and blasts forward. Where his
    friends have to split off and fly around the final mountain peak, the
    electric wingsuit allows him to accelerate up and over it.

    The electric wingsuit can add 15 kW of electric power to your flight
    for up to five minutes, enabling wingsuit pilots to accelerate and
    climb for the first timeBMW

    It's not going to blow Yves Rossy's skirt up; the Swiss "Jetman" has
    four incredibly powerful jet turbine engines on his extraordinary full
    carbon jetwing design, which allow him to blast off vertically from
    the ground with computer-controlled stabilization, and shoot
    vertically upwards like a rocket as well as swooping and soaring like
    a 400-km/h (250-mph) eagle.

    But jet turbines are insanely expensive, and so noisy that they rattle windowpanes from miles away. The average wingsuit pilot's chances of
    ever flying one are very limited. Salzmann's design, on the other
    hand, looks much more promising. The electric wingsuit has had the
    full BMW design touch applied to it; it looks very nicely put
    together, and, dare we say, much more like a product than a prototype.

    Nobody's saying anything about these things being for sale yet, either
    now or into the future, but a small electric propulsion unit is not
    going to cost jet turbine money, and it's hard to imagine an
    adrenaline-fueled wingsuit pilot in the world that wouldn't be
    interested in getting that little bit closer to the Icarus dream of
    soaring through the sky, rising and gliding at will.

    Indeed, the main issue may turn out to be whether a company like BMW
    wants its logo on a product that potentially makes its owners go
    splat. It's one thing to be making promo videos for world-first
    innovations like this, and another altogether to release these tools
    into the hands of extreme sportsfolk where the difference between
    successful and unsuccessful flights can be so gruesome. Things have
    come a long way since the first "wing suit" flight – a brief and
    messily fatal leap off the Eiffel tower by Franz Reichelt in 1912 –
    but wingsuity types don't seem to be able to get their pulses racing
    without cutting things really fine.

    Still, I think we can all rest assured that we'll see more of Salzmann
    and this device as things develop, and that consumer-grade electric
    wingsuits will soon be a thing, and that this public debut is a
    significant moment in personal flight and extreme sports. Enjoy the
    video below.

    One cool thing about electric is the near-instant start and stop. So
    five minutes of running time potentially means way more total flight
    time. (Some of the small jet turbines can't start at all without
    external support.) And every increment in battery capacity goes right
    to more flying.

    This is so beyond amazing. I was just in those mountains two summers
    ago and I would have loved to have seen this live! But alas wingsuit
    flying is a 10 on my (anyone's?) pucker factor (free climbing is an
    11), and I never go past a 7 (rock climbing with a rope or jumping out
    of a normal airplane with a normal parachute). 9 is base jumping. 8 is
    bungee. I'll stick with 7...

    I think "splat" is appropriate! ============================================================


    An icy alpine wind blows in his face, but Peter Salzmann smiles anyway
    – the moment the Austrian wingsuit pilot has long been looking forward
    to is finally here! The helicopter takes him up to a height of 10,000
    feet (3,000 m). You can already make out the outline of the Drei
    Brüder or “Three Brothers” mountain peaks through the cloud cover. In
    a few seconds, Salzmann will fulfill a long-awaited dream – that of
    basejumping in a wingsuit that, thanks to an electric motor, will
    allow him to fly over the “Three Brothers”. During the approach,
    Salzmann goes through all the processes in his mind one last time,
    almost meditatively. He closes his eyes, flies the stretch ahead in
    his mind’s eye, lightly moving his head, upper body and hands as he
    does so. Three years of work, research and testing for this one
    moment. He exhales, supports himself briefly on the left and right
    sides of the open helicopter door… and jumps.

    Flashback: Salzburg, 2017. The idea for this visionary project arises spontaneously after work one day. “At the time, I was developing suits
    for skydiving and basejumping with a friend and basejumping mentor,”
    Peter Salzmann explains. “In a relaxed atmosphere one evening after a
    day of testing, we threw out lots of ideas about how we could improve performance. One of them was a supporting motor – and it’s an idea I
    just couldn’t shake. I found the idea of being able to jump from my
    local mountain wearing the wingsuit and land in my garden

    The Austrian has always dreamed of flying. As a small boy he would
    jump off anything that raised him above the ground and land on
    mattresses or pillows. “Flying is freedom. It’s the ultimate
    expression of striving for the unknown and discovering new horizons,”
    says Salzmann. As a stuntman, basejumper, flight instructor and
    wingsuit pilot, he actually managed to turn flying into his profession
    – a full-time occupation that has allowed him to follow a path that he
    always saw mapped out for him. “I only want to do things that are
    close to my heart,” reports the 33-year-old. “Yet I always knew there
    was more.”

    The wiry, toned athlete comes across as relaxed and down-to-earth, but
    with a charisma that instantly casts a spell over you. For weeks,
    Salzmann worked in his garage at home on ways to implement the idea of
    a wingsuit with assistive propulsion technology with the aim of
    propelling on his sport and entering new, unknown territory. The
    Austria native wants to increase his gliding time, take off from
    greater heights, fly further than ever before and land safely in a
    suitable place. “I quickly came up with the idea of an impeller, in
    other words a propeller enclosed by a ring or tube-shaped housing.
    However, a fuel-powered or conventional motor was out of the
    question,” Salzmann points out. “Sustainability is very important to
    me, and something I try to live my everyday life by. I enjoy nature
    from the air and on the ground – that’s why I aim to consistently
    follow the path of sustainability even when it comes to mobility. With
    the fully electric BMW iX3, I can now do that when preparing for my
    latest jumps – and thanks in no small part to the support of BMW i,
    the progress in electrification has made my dream possible.”

    There comes a time in life when you have to decide whether you want to
    continue doing what you’ve always done, or whether you want to try
    something new. Peter Salzmann wants to progress, but he also knows
    that he needs expert help to do so. And he finds it at BMW i in 2017.
    “Our future-oriented approach with electric propulsion systems and
    innovative materials and technologies were a perfect fit for Peter
    Salzmann’s unusual but fascinating idea. In my opinion, Peter Salzmann perfectly embodies the attitude of the BMW i brand with his unique
    vision, his passion and his courage. I was also very impressed by his
    physical effort, combined with in-depth technical knowledge and a very
    clear understanding of the brand,” says Stefan Ponikva, at the time
    patron of the project at BMW i and now Vice President Brand

    With one eye on the simultaneous development of the fully electric BMW
    iX3, the solution was obvious – they would develop an electric
    wingsuit together. They would develop an electric propulsion system
    for lofty heights – powered by renewable energy, compact enough to
    work with a regular wingsuit, and with limited heat generation – an
    enhancement of the well-known fly suit design that would enable an
    immediate start and a truly agile flight experience. “I enjoy tackling challenges like this. Developing new suits, testing new equipment and
    promoting the sport of wingsuit flying in different ways – that’s what
    drives me,” says Salzmann. “And in BMW I’ve found the perfect creative
    partner to realize the project with the highest safety standards and
    all the necessary development steps.”

    At the same time, close contact was established – through BMW i – with Designworks, the BMW Group’s design innovation studio. The studio
    provided Salzmann with experts to work with the wingsuit pilot on
    developing the fly suit adapted to the new propulsion technology, and
    the electric impeller. “From a technical standpoint we brought in
    Designworks, who are experts in bringing together the needs of
    mobility and other sectors,” added Ponikva. Realizing this vision
    together with his team was a personal moment of joy for him. “Only an
    electric impeller is lightweight and agile enough to enable regular
    wingsuit flying and basejumping. Light enough to climb mountains with,
    agile enough to fly tight turns and maneuvers, and yet quiet enough
    not to disturb the purity of the flight.”

    The electrified wingsuit flight was a project close to my heart and,
    through the literal elevation of our BMW i technology, an innovative communication statement.

    Ideas became sketches, sketches became digital models, and digital
    models became the first prototypes. “The very first one was made of
    cardboard – and I built it so that I could get a feel for the size of
    the fly unit, i.e. the impeller unit including the batteries and
    everything that goes with it,” explains Salzmann. Two models were
    produced, one large and one smaller unit. The next step was an
    aluminum prototype that did not, however, contain any impellers or
    electronics. It was used to simulate the weight and dimensions and was
    worn by Salzmann with a harness and breast piece.

    “The development process was a constant up and down, we were always
    facing new challenges,” reveals Salzmann. “Initially we were going to
    put the propulsion unit on the back. But after the initial drawings
    and discussions with aerodynamics experts, we decided to move the fly
    unit to the front.” Salzmann and the team also quickly had to abandon
    the plan to use the larger version of the impeller, and the extra 40%
    of output it offered. “The very first time I tried the fly suit on, it
    was clear to me that the whole thing would be too heavy and that I
    would only have limited movement. The thing is, comfort and feeling
    safe are the most important things when jumping, and I also need
    freedom of movement so that I can open the parachute later.” The
    engineers therefore focused on the smaller model – still around 40
    inches (1 m) wide – which was then fine-tuned via wind tunnel testing.
    The final fly unit, with its two propellers, each around 5 inches (13
    cm) in diameter, ultimately resembles a futuristic mini-submarine. It
    gets its electricity from a 50 V lithium battery, weighs in at around
    26 lbs (12 kg) and is attached to the pilot’s breastplate by means of
    a hinge unit. The two carbon impellers in the lightweight carbon fiber
    and aluminum structure have a combined output of 15 kilowatts and run
    at a speed of around 25,000 rpm.

    The first series of tests with the fly suit were carried out in the
    AEROLAB, BMW’s horizontal wind tunnel. The wind tunnel testing was
    used to validate and compare the various impeller variants and
    wingsuits. “During the first few runs we tested the entire ensemble
    with a dummy, but with the original impellers and wingsuits, and
    measured all forces and moments. We then decided on a variant of the
    impeller and the specific positioning,” explains Salzmann. The next
    step involved a trip to Sweden. “The first test in the wingsuit wind
    tunnel in Stockholm was a milestone for me. I couldn’t stop grinning.
    Because until that moment I had no idea whether I could control a
    flight with the impeller. This skydiving wind tunnel is the only one
    in the world where a wingsuit pilot can fly indoors. Here I was able
    to simulate the flight and also test whether I could open my parachute
    without problem. And it felt so stable! I knew then that we were on
    the right track.” With this preliminary design of the propulsion unit,
    Salzmann then performed the first test jumps from a helicopter in
    order to get a feel for the influence of the equipment on flight
    behavior. In the next step, two prototypes were constructed with the
    impeller, battery technology and the necessary electronics built in,
    and then it was time to hit the air.

    Salzmann completed more than 30 test jumps with the fly unit. “After
    evaluating the initial jumps, we came to the conclusion that the
    impellers were still not getting enough air flow. We therefore
    integrated additional air inlets into the wingsuit.” The propulsion
    system was designed in close cooperation with BMW i and Designworks
    and optimized down to the smallest detail. Another discovery was that
    the weight was too high and had to be reduced. “And we had to come up
    with an emergency cut-off solution for the fly unit, develop a
    steering facility and position an on/off switch in such a way that I
    could easily operate it at any time. This throttle is now on the left
    sleeve and can be controlled with the middle and ring fingers.”

    It’s early morning and the sun is slowly rising over the Drei Brüder
    peaks in the Hohe Tauern mountain range in the Alps. The countdown is
    on; in half an hour Peter Salzmann will launch the pivotal jump. The electrified wingsuit has been checked down to the last detail, every
    screw and every seam on the equipment inspected. While the prospect of
    jumping from 10,000 feet (3,000 m) or more would definitely make
    others nervous, Peter Salzmann remains cool and carefree. Calm, but
    visibly energized, he explains to his team how he intends to complete
    the flight. It was actually supposed to have taken place on the other
    side of the world – Salzmann originally planned to complete this jump
    in Korea in the spring of 2020. But the outbreak of the COVID-19
    pandemic put a stop to his plans for a world premiere in Korea. Then,
    after months of uncertainty, relief was finally forthcoming. When the
    pandemic began to abate, the project got back on track and the new
    location in Austria was found. The team was able to resume planning,
    equipment testing and test jumps. Now, a few months later, Salzmann’s
    dream of flying in a way no-one has ever flown before is about to be

    Electrified Wingsuit Wingsuit Peter Salzmann Wingsuit Pilot fly suit

    Is he nervous? No. “There’s always a certain amount of tension, of
    course, and that’s a good thing. You always have to be aware of the consequences of mistakes. With this amount of speed and physical
    strain, everything has to be done right. Over the years I’ve
    cultivated a level of experience that now gives me the security of
    sitting in the helicopter with a smile, even if that might surprise
    some people out there. When the chopper takes off, the equipment has
    been checked and I’ve gone over the processes point by point in my
    head. For me, the journey up is now just one thing: pure
    anticipation.” A jump not only requires mental strength, but also
    physical fitness, explains Salzmann, assuming a flight position to
    illustrate. “The load on the body is enormous, especially with
    additional equipment. I can keep my arms in this outstretched position
    for about five minutes. I’ve been doing special training every day for
    months to strengthen my core, neck and shoulder muscles.”

    3, 2, 1, Go! Salzmann receives the long-awaited signal over the radio.
    Viewed from the ground, the wingsuit pilot is initially just a small
    dot in the sky, but quickly gets closer. As the helicopter veers off,
    Salzmann quickly picks up speed in his fly suit. He rushes past rock
    faces with a gap of just a few feet (1-2 m) as heads towards the
    valley. In flight, Salzmann always focuses on specific points along
    the mountain in order to maintain his course and to be able to react
    in good time if necessary. Yet the Austrian is very much in his

    Making the future tangible – from a crazy idea to its realization –
    there’s no better reward than being able to realize your vision. I’m
    so proud that the team got the job done... and when I saw the first
    video of Peter gaining altitude while the other pilots descend, I was
    literally speechless!
    Holger Hampf
    President of Designworks

    For three years he has given everything for this moment. In the past
    two years he has jumped more often than ever before – and faced
    situations where he went outside the envelope. Then, the time has
    come: he pulls the slider towards him with his middle and ring fingers
    – and is pushed back up from the descent, as if by invisible forces,
    by the electric propulsion system he has activated. Salzmann’s efforts
    and toil are rewarded, just as he imagined – with a quiet moment of
    euphoria at a height of over 3,000 feet (over 1,000 m). Just before he
    opens his parachute, he enjoys the last few electrified yards or
    meters of thrust, breathes out, and pull his ‘chute. In order to
    redefine the limits of his sport, he pushed himself to his own limits.

    It’s now afternoon at the Drei Brüder. Peter Salzmann has landed
    safely; he packs up his parachute, carefully attaches the impeller
    onto a specially made mobile holder unit that is a little reminiscent
    of a modified hand cart, and stows the rest of the equipment in his
    BMW iX3. A look back toward the mountains, then it’s time for home and
    family. The feeling of exhilaration from the flight will stay with him
    on his journey home. “For me, driving this new electric BMW iX3 has
    parallels to my wingsuit experience. The sound is similar, as is the
    feeling of immediate acceleration.

    It’s impressive and it feels good to be continuing on my sustainable
    path through electromobility, whether that’s on the road or in the
    air.” Peter Salzmann is not one for resting on his laurels. The
    daredevil wants to go even higher. The South Korea plan has only been postponed, not cancelled – the energetic Austrian wants to fly between high-rise buildings there. “I will have to train more. We will
    optimize the technique and look ahead boldly.”

    The art of progress, after all, lies in bursting free of the familiar
    and breaking new ground.
