POF - Aerodynamics of maneuvering flight

Question 1

flight path where forces are in equilibrium but flight path is inclined

Answer 1

climbing flight

Question 2

excess __ not lift is necessary for a sustained climb.

Answer 2

excess thrust

Question 3

left turning tendency - incorporates newton’s third law of motion. Opposite reaction created by the turning propeller.

Answer 3

Torque

Question 4

left turning tendency - force applied to the rim of a rotating disc. exhibits a characteristic of a gyroscope - rigidity in space and precession.

Answer 4

gyroscopic precession

Question 5

left turning tendency - the descending blade of the propeller takes a greater bite of air than the ascending blade.

Answer 5

Asymmetrical Thrust

Question 6

left turning tendency - as propeller rotates, it produces a backward flow of air which wraps around the airplane.

Answer 6

spiraling slipstream

Question 7

flight path where forces are in equilibrium with the force of weight acting perpendicular along the flight path and weight acting forward along the flight path

Answer 7

descending flight

Question 8

used to measure the gliding efficiency of your airplane. The AoA resulting in the least drag will give the Maximum Lift-to-Drag Ratio (L/D max).

Answer 8

lift to drag ratio

Question 9

the speed that will give you the maximum glide distance.

Answer 9

best glide speed

Question 10

the distance the plane will travel forward, without power, in relation to altitude loss.

Answer 10

glide ratio

Question 11

angle between glide path and the horizon.

Answer 11

glide angle

Question 12

factors affecting glide

Answer 12

Weight- a heavier plane needs a higher speed to maintain the same gliding efficiency as the lighter plane with the same aerodynamics.

Configuration- extending gears will increase drag thus reducing L/D max and Glide ratio.

Wind- a tailwind increases glide distance while a headwind decreases it.

Question 13

causes the airplane to turn

Answer 13

horizontal component of lift

Question 14

supports the weight of the airplane

Answer 14

vertical component of lift

Question 15

also called as horizontal component of lift, is directed inward towards the center of rotation

Answer 15

centripetal force

Question 16

force opposing centripetal force, acts outward from the center of the rotation

Answer 16

centrifugal force

Question 17

the aileron on the inside wing is raised and the aileron on the outside wing is lowered which causes an increase in angle of attack and produces more lift for that wing

Answer 17

adverse yaw

Question 18

caused by the additional lift on the outside wing; outside wing travel faster than the inside wing

Answer 18

over-banking tendency

Question 19

is the ratio of the total load supported by the airplane’s wing ( lift ) to the actual weight of the airplane.

Answer 19

load factor

Question 20

g factor where force acts in the same direction as weight

Answer 20

(-) load

Question 21

g factor where force acts the opposite direction as weight

Answer 21

(+)

Question 22

is the number of G’s an airplane can sustain on a continuing basis without causing permanent structural damage

Answer 22

limit load factor
