I wrote one of these rounds.

* Game 10, Round 4 - Entertainment (sort of) - Oddly Named Musical Instruments

In each case, tell us the letter of the relevant illustration on
the 2-page handout:

http://www.eskimo.com/~scs/msb/oo10/4/ins.pdf

1. Sousaphone.
2. Balalaika.
3. Krummhorn, a medieval member of the oboe family.
4. Serpent.
5. Fife.
6. Clarinette d'amour.
7. Racket, an old, oddly shaped member of the oboe family.
8. Theorbo, a Renaissance-era member of the lute family.
9. Heckelphone, a member of the oboe family.
10. Hurdy-gurdy, a member of the violin family with a keyboard
and a crank.

So there were 6 decoys. Decode the rot13 if you would like to
see the other instruments and find them for fun, but for no points:

11. Angheny ubea.
12. Bcuvpyrvqr.
13. Xrlrq syntrbyrg.
14. Yhe, na byq oenff vafgehzrag.
15. Pvggrea be Ratyvfu thvgne.
16. Cvotbea, na bofbyrgr zrzore bs gur pynevarg snzvyl.

* 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.

the crankshaft is stationary and the cylinders rotate around it as a
unit, directly attached to the propeller.

(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.

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.

(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.

(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.

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.

Bell; Buffalo (Niagara Falls was close enough). 4 for Bruce, Stephen
