New Specification for Light Sport Gyroplane Rotor System

1. Scope

This specification covers minimum requirements for the design and testing of rotors for light sport category gyroplanes. The rotor system is considered to include rotor blades, hub bar, connection structure of hub bar to the rotor blades as well as teeter block.

Keywords

lsa; gyroplane; light sport aircraft; mosaic; rotor system

Rationale

Rotors that provide the principal lift for gyroplanes have an airfoil profile and fixed pitch blades in flight to enable pitch and roll using a cyclic control. Light Sport Gyroplane rotors are restricted to two blade teetering rotors only to mitigate ground resonance and other complications to a minimum.

The title and scope are in draft form and are under development within this ASTM Committee.
