Ch 3C - Aerodynamics of Maneuvering Flight Flashcards
In climbing flight
One component of weight acts perpendicular to the flight path and the another component of weight acts rearward, in the same direction as drag
Four left-turning tendencies associated with propeller-driven airplanes are
Torque, gyroscopic precession, asymmetrical thrust, spiraling slipstream
In descending flight
One component of weight acts forward along the flight path and another acts perpendicular to the flight path
Maintaining the angle of attack that corresponds to L/Dmax will produce
The least drag, best glide angle, and maximum gliding distance
Changes in weight will not affect
Glide ratio but a higher airspeed will have to be maintained in a heavier aircraft in order to cover the same distance over the ground
Center seeking force that acts on a turning airplane
Centripetal force, which is created by the horizontal component of lift
The effects of adverse yaw can be countered by maintaining a coordinated turn using
Rudder
As angle of bank is increased in a constant airspeed turn
The rate of turn increases and radius of turn decreases
As airspeed is increased and angle of bank held constant
The rate of turn will decrease and turn radius will increase
Load factor
The ratio of the weight that the wings must support to the actual weight of the aircraft
Accelerated stalls occur
When the critical angle of attack is exceeded at an airspeed higher than the one-G stall speed
The V-g diagram defines the airplanes
Envelope, which is bounded by the stall region, limit load factor, and V^ne
The four fundamentals involved in maneuvering an aircraft are
Straight-and-level flight, turns, climbs, and descents
Torque effect is greatest at
Low airspeeds, high power settings and high angle of attack
P-factor
Causes left yaw at high angles of attack; caused by descending propeller blade on the right producing more thrust than the ascending blade on the left
