Than a conventional autogyro but slower than gyrodynes of the 1950s.Ī helicopter to go the same speed would need almost twice this power. Thus theĬarterCopter seems to be about twice as efficient.įrom 1999 to 2001 there were 4 recorded instances of non-fatal crashes. Prototype has achieved is about 173 mph (270 km/h) which is still ~40% faster Limited to just 320 hp (240 kW) and the fastest Carter Aviation Technologies (800 km/h), which would be about twice as fast as any helicopter has everĪt present, the prototype's engine is normally aspirated, and hence is The claimed theoretical maximum speed of a CarterCopter is around 500 mph The rotors would still experience flapping as they rotateĭue to dissymmetry of lift lift between the two sides of the vehicle, but Carter This means that a CarterCopter can theoretically fly much faster than the tip Since the rotor is unloaded, the aerodynamic forces on the rotor are very minor. However, with the CarterCopter, the fixed wings keep the vehicle at theĬorrect angle to the horizon and provide the lift required to remain aloft. The vehicle would 'fall over' due to retreating Stop in the air, whilst the leading rotor blade would be traveling at twice the This is because the retreating rotor blade would Normally a helicopter or gyrocopter cannot fly forward at the same speed (orįaster) as its rotor tip speed. It keeps the rotor rigid, preventing excessive flapping. Although the rotor is unused at high speed, the rotor is kept spinning as Little lift, dramatically reducing the amount of induced drag created by the The pilotĬan then flatten the angle of attack of the main rotor so it produces very (140 km/h), its stubby, lightweight wings provide most of the lift. Once the CarterCopter gets up to a forward speed of about 90 miles per hour Main rotor, spinning it faster and generating more lift. The pilot then applies full power to the rear pusher propeller and The aircraft's main rotor has enough momentum due to heavy counterweights in The angle of attack of the main rotor blades is increased suddenly so that the The rotor is then disconnected from the engine and Carter Aviation also claims the system is safer than aĬarterCopter should be capable of the higher airspeeds that can only be achievedīy fixed wing aircraft, but also able to land in any small area in anĪt takeoff the pilot angles the top rotor flat (zero angle of attack) and To leverage the advantages of fixed wings as well as gyrocopters, giving almostĪll the capabilities of helicopters (except hovering) but with a relatively Little drag, and the company claims that the aircraft would be potentially able The low rotation speed and flat feathering of the rotor means that it causes Helicopter this would cause massive lift asymmetry and insoluble control issuesīut the fixed wings keep the aircraft in the air and stable. The rotor spins with a tip speed belowĪirspeed, which means that the retreating blade flies completely stalled. Wings, with the rotor simply windmilling. Very brief hover, and can land more or less vertically.Īt high speed (above about 100 mph) the aircraft flies mostly using the fixed At low speed, the vehicleįlies as a gyrocopter, and can pre-spin the rotor for a vertical takeoff and Heavy rotor, supplemented with conventional wings. The CarterCopter concept is a gyrocopter with an unusually stiff, relatively It is an all-composite design The tricycle undercarriage is retractable. The rotor is a two-bladed design weighted with 55 pounds The Carter copter is a pusher configuration autogyro with wingsĪnd a twin boom tail.
