Authors Abstract
Content
VARIOUS structural problems encountered in the design of high-speed turboprop propellers are discussed in this paper.
Formulas for a number of design factors are also given here. These include:
  1. 1.
    Blade efficiency.
  2. 2.
    Power capacity.
  3. 3.
    Advance/diameter ratio.
  4. 4.
    Limiting tip speed.
  5. 5.
    Periodic lift.
  6. 6.
    Propeller normal force and moment.
The paper also describes two types of vibration occurring with turboprop installations:
  1. 1.
    First-ordered aerodynamically excited vibration.
  2. 2.
    Subsonic stall flutter.
The author shows how these vibrations may be accurately predicted and controlled by proper design of the propeller blades.
