Safety Features Shorter rotor blades allow greater angles of aircraft to ground without rotor hitting ground No tail rotor Symmetry of lift and controls makes for easier flying, thereby reducing pilot error Semi rigid rotor system makes it impossible for rotor to bump mast or tail boom High minimum airspeed of the inner rotor section minimizes the chances of blade stall under powered descent and during maneuvers The ability to land virtually anywhere if difficulties should arise, e.g.. Inclement weather, engine failure. The ability to glide to landing The engine to rotor layout minimizes the amount and the direction of engine torque being transmitted to the fuselage, thereby reducing possible ground resonance Semi rigid rotor system gives pilot greater "feel" and more control and allows greater freedom in load distribution. Counter rotating rotors negate gyroscopic precession Shorter rotor blades minimize out of balance rotors due to "hooks joint effect" Virtually zero negative airflow on retreating blade reduces the chance of loss of control at high speeds All controls are positively linked, reducing the need for gimmicky set up to enable control. No sideways push due to tail rotor and rotor shaft angle reduces collision possibilities But wait, that’s not all !!! |
