What you will learn
On successful completion of this module you should be able to:
- Describe the aerodynamic principles of RW flight,
- Estimate RW component power requirements,
- Evaluate aspects of the performance of a RW platform.
RW a/c definitions; configurations and layout.
Rotor axial flight performance:
rotor definitions, thrust, induced velocity, induced power, profile and climb power in axial flight, flow states in axial flight, effects of blade geometry, rotor coefficients, disc loading and blade loading, rotor figure of merit, ground effect,vertical autorotation.
collective and cyclic controls, feathering, flapping and lagging; fully-articulated, hingeless, elastomeric and bearingless rotors; teetering rotors, swash plate and spider, rotor RPM control, rotor moments.
Rotor forward flight:
thrust, induced velocity, induced power and profile power in forward flight, blade cyclic variation of speed and incidence, flap back, rotor limitations due to compressibility and stall and the effect on aircraft performance, dynamic stall effects, tip modifications, ABC, compounding, etc.
Rotary wing aircraft performance:
parasite power, minimum power and minimum drag speeds, maximum speed, range and endurance, take-off and climb, forward flight descent and autorotation, hover ceiling IGE and OGE.
RW aircraft trim, stability and control:
control at the hover and in forward flight, effect of rotor head design, rotor stability with respect to incidence and speed, rotor lag, a/c longitudinal, lateral and directional static and dynamic stability at the hover and in forward flight. manoeuvrability and agility.
Cross-couplings and vibrations:
examples of cross-coupling effects, ground resonance, introduction to helicopter vibration, vibration absorbers, ACSR.
transmission layouts for single and multi-rotor helicopters.
Tutorials, practical demonstrations and a case study.
