Question 1

Factor inversely affects a propeller’s angle of attack

Answer 1

Propellor pitch

Question 2

Propellor pitch

Answer 2

Factor inversely affects a propeller’s angle of attack

Question 3

These engines are a good choice for supersonic aircraft because of their simple internal structure

Answer 3

Ramjet

Question 4

Ramjet

Answer 4

good choice for supersonic aircraft because of their simple internal structure

Question 5

Single engine aircraft tend to roll without pilot input because of this

Answer 5

Conversation of angular momentum

Question 6

Lightweight engines with 8-10k RPM

Answer 6

Turbojet

Question 7

Turbojet

Answer 7

Lightweight engines with 8-10k RPM

Question 8

Turbofan engines are chosen because they allow engineers to lower this quantity

Answer 8

Airspeed

Question 9

Because rockets carry their own propellant, this quantity is always at least as large as for air-breathing engines having similar airspeed and wash speed

Answer 9

Propulsive efficiency

Question 10

Used to reduce the pumping losses in air-breathing engines and to increase service ceiling

Answer 10

Turbocharger

Question 11

Along with wash speed, this property of the propulsion system increases the maximum for cruising speed of air-breathing aircraft

Answer 11

Mass flow rate
