A turboprop engine where the gas producer spool is directly connected to the output shaft.
Industry:Aviation
Propellers with fixed blade angles. Fixed-pitch propellers are designed as climb propellers, cruise propellers, or standard propellers.
Industry:Aviation
Hinged portion of the trailing edge between the ailerons and fuselage. In some aircraft, ailerons and flaps are interconnected to produce full-span “flaperons.” In either case, flaps change the lift and drag on the wing.
Industry:Aviation
A propeller configuration when the blade chord is aligned with the direction of rotation.
Industry:Aviation
A disorientating condition caused from flickering light off the blades of the propeller.
Industry:Aviation
An automatic flight control system in which the commands needed to fly the airplane are electronically computed and displayed on a flight instrument. The commands are followed by the human pilot with manual control inputs or, in the case of an autopilot system, sent to servos that move the flight controls.
Industry:Aviation
Engine speed, usually in the 70-80 percent range, for minimum flight thrust.
Industry:Aviation
A condition when landing where the airplane does not settle to the runway due to excessive airspeed.
Industry:Aviation
The energy applied to an object that attempts to cause the object to change its direction, speed, or motion. In aerodynamics, it is expressed as F, T (thrust), L (lift), W (weight), or D (drag), usually in pounds.
Industry:Aviation
The part of parasite drag on a body resulting from the integrated effect of the static pressure acting normal to its surface resolved in the drag direction.
