• RQFTCI98 Game 10 Rounds 4,6: instruments, aeronautics

    From Mark Brader@21:1/5 to All on Thu Jul 1 23:47:56 2021
    These questions were written to be asked in Toronto on 1998-04-06, and
    should be interpreted accordingly. All questions were written by
    members of the Usual Suspects, but have been reformatted and may have
    been retyped and/or edited by me. I will reveal the correct answers in
    about 3 days.

    For further information, including an explanation of the """ notation
    that may appear in these rounds, see my 2020-06-23 companion posting on "Reposted Questions from the Canadian Inquisition (RQFTCI*)".


    I wrote one of these rounds.

    * Game 10, Round 6 - Science - Aeronautics

    In this round where we ask for a company, you can give its usual
    short name, e.g. Boeing. Where we ask for a model of aircraft,
    you need not name the manufacturer and can just give the major
    model name or number, such as 747.

    1. Most early jet engines were turbojets, in which the air from
    the intake
    * is compressed by a turbine;
    * enters the combustion chamber where it is heated by
    burning fuel;
    * powers a second turbine that drives the first one;
    * rushes forcefully out the exhaust to yield forward thrust.

    Most jet engines on modern airliners include an important
    variation on this design, which makes them wider but improves
    fuel economy. Tell briefly what is different about this design,
    or say what these engines are called.

    2. An engine design once very popular was the radial, which featured
    a ring of cylinders at various angles surrounding a central
    crankshaft which drove the propeller. A variant of this design
    called the rotary engine enjoyed some success during World War I.
    How did the rotary differ from the conventional radial?

    3. This twin-engine airliner, which carried 21 passengers in its
    usual seating configuration, entered commercial service in 1936
    and was the most successful and durable of its era, commanding
    at one point 80% of the US market. Name it.

    4. The first comparable success of the jet era was the Boeing 707,
    but you knew that. The *first* jet airliners made their
    test flights in 1949. A British design was first to enter
    commercial service, but in its initial form it proved to have
    a fatal design flaw. A Canadian design looked promising in its
    test flights, but never entered commercial service due to lack
    of airline interest and diversion of manufacturing capacity to
    Korean War fighters. Name *either* of these two planes.

    5. In a conventional airplane, if it is to be rolled (that is,
    banked to the left or right), a control surface is raised on one
    wing and lowered on the other. What are these paired control
    surfaces called?

    6. In a conventional airplane, if it is to be pitched upward
    (that is, the nose is to be raised), a control surface is
    raised on the tail, or perhaps one on each half of the tail.
    What is this control surface called?

    7. In many modern fighters, and some commercial airliners such
    as the Airbus A320 and Boeing 777, control surfaces such as
    <answers 5 and 6> no longer have any mechanical linkage to the
    pilot's controls; instead they have their own motors that are
    actuated through a computer. What phrase of three short words
    is used informally to describe this system?

    8. In the Wright Brothers' original airplane, the structures
    equivalent to the modern tailplane and <answer 6> were located at
    the front. While this has become a rare design, it continues to
    be seen from time to time in exotic aircraft. The word "tail"
    would not be sensible for a forward structure like this; what
    French word is applied to it?

    9. Everyone knows that in 1947 the X-1, piloted by Chuck Yeager,
    became the first plane to fly faster than sound. Tell us
    *either* the company or the American city that the X-1 came
    from. In later years the company has been best known for
    their helicopters.

    10. The reconnaissance planes called the U-2 and the SR-71
    Blackbird, as well as the F-117A stealth fighter, all came from
    the same division of the same company. The division took its
    informal name from a phrase in a comic strip. Either give this
    name, or name the company.

    1. Most early jet engines were turbojets, in which the air from
    the intake
    * is compressed by a turbine;
    * enters the combustion chamber where it is heated by
    burning fuel;
    * powers a second turbine that drives the first one;

    3. This twin-engine airliner, which carried 21 passengers in its
    usual seating configuration, entered commercial service in 1936
    and was the most successful and durable of its era, commanding
    at one point 80% of the US market. Name it.

    5. In a conventional airplane, if it is to be rolled (that is,
    banked to the left or right), a control surface is raised on one
    wing and lowered on the other. What are these paired control
    surfaces called?

    aileron

    6. In a conventional airplane, if it is to be pitched upward
    (that is, the nose is to be raised), a control surface is
    raised on the tail, or perhaps one on each half of the tail.
    What is this control surface called?

    rudder

    7. In many modern fighters, and some commercial airliners such
    as the Airbus A320 and Boeing 777, control surfaces such as
    <answers 5 and 6> no longer have any mechanical linkage to the
    pilot's controls; instead they have their own motors that are
    actuated through a computer. What phrase of three short words
    is used informally to describe this system?

    fly by wire

    9. Everyone knows that in 1947 the X-1, piloted by Chuck Yeager,
    became the first plane to fly faster than sound. Tell us
    *either* the company or the American city that the X-1 came
    from. In later years the company has been best known for
    their helicopters.

    10. The reconnaissance planes called the U-2 and the SR-71
    Blackbird, as well as the F-117A stealth fighter, all came from
    the same division of the same company. The division took its
    informal name from a phrase in a comic strip. Either give this
    name, or name the company.

    * Game 10, Round 6 - Science - Aeronautics

    In this round where we ask for a company, you can give its usual
    short name, e.g. Boeing. Where we ask for a model of aircraft,
    you need not name the manufacturer and can just give the major
    model name or number, such as 747.

    1. Most early jet engines were turbojets, in which the air from
    the intake
    * is compressed by a turbine;
    * enters the combustion chamber where it is heated by
    burning fuel;
    * powers a second turbine that drives the first one;
    * rushes forcefully out the exhaust to yield forward thrust.

    Most jet engines on modern airliners include an important
    variation on this design, which makes them wider but improves
    fuel economy. Tell briefly what is different about this design,
    or say what these engines are called.

    2. An engine design once very popular was the radial, which featured
    a ring of cylinders at various angles surrounding a central
    crankshaft which drove the propeller. A variant of this design
    called the rotary engine enjoyed some success during World War I.
    How did the rotary differ from the conventional radial?

    3. This twin-engine airliner, which carried 21 passengers in its
    usual seating configuration, entered commercial service in 1936
    and was the most successful and durable of its era, commanding
    at one point 80% of the US market. Name it.

    4. The first comparable success of the jet era was the Boeing 707,
    but you knew that. The *first* jet airliners made their
    test flights in 1949. A British design was first to enter
    commercial service, but in its initial form it proved to have
    a fatal design flaw. A Canadian design looked promising in its
    test flights, but never entered commercial service due to lack
    of airline interest and diversion of manufacturing capacity to
    Korean War fighters. Name *either* of these two planes.

    5. In a conventional airplane, if it is to be rolled (that is,
    banked to the left or right), a control surface is raised on one
    wing and lowered on the other. What are these paired control
    surfaces called?

    Ailerons


    6. In a conventional airplane, if it is to be pitched upward
    (that is, the nose is to be raised), a control surface is
    raised on the tail, or perhaps one on each half of the tail.
    What is this control surface called?

    Aileron


    7. In many modern fighters, and some commercial airliners such
    as the Airbus A320 and Boeing 777, control surfaces such as
    <answers 5 and 6> no longer have any mechanical linkage to the
    pilot's controls; instead they have their own motors that are
    actuated through a computer. What phrase of three short words
    is used informally to describe this system?

    8. In the Wright Brothers' original airplane, the structures
    equivalent to the modern tailplane and <answer 6> were located at
    the front. While this has become a rare design, it continues to
    be seen from time to time in exotic aircraft. The word "tail"
    would not be sensible for a forward structure like this; what
    French word is applied to it?

    9. Everyone knows that in 1947 the X-1, piloted by Chuck Yeager,
    became the first plane to fly faster than sound. Tell us
    *either* the company or the American city that the X-1 came
    from. In later years the company has been best known for
    their helicopters.

    Sikorsky


    10. The reconnaissance planes called the U-2 and the SR-71
    Blackbird, as well as the F-117A stealth fighter, all came from

    This was the 6th-easiest round of the season, probably because
    it included too many hints.

    Was Stephen's answer "j" a typo? The natural horn doesn't come
    close to meeting the description.

    * Game 10, Round 6 - Science - Aeronautics

    This was the 5th-hardest round of the season.

    In this round where we ask for a company, you can give its usual
    short name, e.g. Boeing. Where we ask for a model of aircraft,
    you need not name the manufacturer and can just give the major
    model name or number, such as 747.

    1. Most early jet engines were turbojets, in which the air from
    the intake
    * is compressed by a turbine;
    * enters the combustion chamber where it is heated by
    burning fuel;
    * powers a second turbine that drives the first one;
    * rushes forcefully out the exhaust to yield forward thrust.

    Most jet engines on modern airliners include an important
    variation on this design, which makes them wider but improves
    fuel economy. Tell briefly what is different about this design,
    or say what these engines are called.

    (High-bypass) turbofans. The compressor is enlarged into (or
    augmented with) a "fan", so that some air from the intake is blown
    directly into the exhaust, bypassing the combustion chamber. This air
    provides a majority of the thrust; in effect the fan is doubling
    as a propeller. (Any short answer along these lines or mentioning
    "fan" or "bypass" was fine.) 4 for Dan Tilque, Stephen, and Dan Blum.

    2. An engine design once very popular was the radial, which featured
    a ring of cylinders at various angles surrounding a central
    crankshaft which drove the propeller. A variant of this design
    called the rotary engine enjoyed some success during World War I.
    How did the rotary differ from the conventional radial?

    The crankshaft stood still and the cylinders rotated around it as a
    unit, attached directly to the propeller. (Anything close was okay.)
    4 for Stephen.

    The main advantage of the rotary was that the cylinders moved
    through the air so fast they needed no other form of cooling.
    One disadvantage was lubricant dripping continuously off the rim of
    the engine -- with consequent, ah, biological effects on the pilot,
    since the usual lubricant was castor oil!

    Another notable quirk was that the gyroscopic effect of the large
    rotating mass made it easier to turn the plane to one side than to
    the other -- which pilots in dogfights had to allow for.

    3. This twin-engine airliner, which carried 21 passengers in its
    usual seating configuration, entered commercial service in 1936
    and was the most successful and durable of its era, commanding
    at one point 80% of the US market. Name it.

    (Douglas) DC-3. Its military names, the Dakota and the C-47 Skytrain,
    were also acceptable. 4 for Bruce, Dan Tilque, Stephen, and Dan Blum.

    4. The first comparable success of the jet era was the Boeing 707,
    but you knew that. The *first* jet airliners made their
    test flights in 1949. A British design was first to enter
    commercial service, but in its initial form it proved to have
    a fatal design flaw. A Canadian design looked promising in its
    test flights, but never entered commercial service due to lack
    of airline interest and diversion of manufacturing capacity to
    Korean War fighters. Name *either* of these two planes.

    (De Havilland) Comet (1), (Avro) (C-102) Jetliner. 4 for Bruce,
    Dan Tilque, and Stephen.

    The Comet 1's design flaw was rectangular windows. Metal fatigue in
    the pressure hull focused on the sharp corners and led to explosive decompression after less than two years of flying.

    5. In a conventional airplane, if it is to be rolled (that is,
    banked to the left or right), a control surface is raised on one
    wing and lowered on the other. What are these paired control
    surfaces called?

    Ailerons. 4 for Bruce, Dan Tilque, Stephen, Dan Blum, and Pete.

    6. In a conventional airplane, if it is to be pitched upward
    (that is, the nose is to be raised), a control surface is
    raised on the tail, or perhaps one on each half of the tail.
    What is this control surface called?

    Elevator. 4 for Bruce, Dan Tilque, and Stephen.

    7. In many modern fighters, and some commercial airliners such
    as the Airbus A320 and Boeing 777, control surfaces such as
    <answers 5 and 6> no longer have any mechanical linkage to the
    pilot's controls; instead they have their own motors that are
    actuated through a computer. What phrase of three short words
    is used informally to describe this system?

    Fly by wire. 4 for Bruce, Dan Tilque, Stephen, and Dan Blum.

    8. In the Wright Brothers' original airplane, the structures
    equivalent to the modern tailplane and <answer 6> were located at
    the front. While this has become a rare design, it continues to
    be seen from time to time in exotic aircraft. The word "tail"
    would not be sensible for a forward structure like this; what
    French word is applied to it?

    Canard. 4 for Bruce, Dan Tilque, and Stephen.

    So named from its resemblance, together with the structure linking
    it to the main part of the plane, to the head and neck of a duck.

    9. Everyone knows that in 1947 the X-1, piloted by Chuck Yeager,
    became the first plane to fly faster than sound. Tell us
    *either* the company or the American city that the X-1 came
    from. In later years the company has been best known for
    their helicopters.

    Bell; Buffalo (Niagara Falls was close enough). 4 for Bruce, Stephen
    (the hard way), and Dan Blum.

    10. The reconnaissance planes called the U-2 and the SR-71
    Blackbird, as well as the F-117A stealth fighter, all came from
    the same division of the same company. The division took its
    informal name from a phrase in a comic strip. Either give this
    name, or name the company.

    Skunk Works (from "Pogo"); Lockheed. 4 for Bruce, Dan Tilque,
    Stephen (the hard way), and Dan Blum.
