6-9 Place Jet Powered Business Air Vehicle
Carter has a concept for a high speed, jet-powered, light business aircraft. It would carry 4 to 6 passengers, and would fly at 300+ kts, 40,000 feet altitude, and have a 2000+ nm range. The aircraft takes advantage of Carter’s SR/C and other technologies. The high inertia rotor allows for vertical takeoffs and landings for runway independence, and acts like a built-in parachute at all airspeeds and altitudes. Slowing the rotor for cruise dramatically reduces drag (more info), and keeps the advancing blade tip Mach number lower than 0.95 at max speed. The fuselage cross sectional area increases for much of the length to help keep a laminar boundary layer for reduced drag.
The engines are located very close together in case of an engine failure on takeoff. Unlike a conventional jet where takeoff speed is high enough for the rudders to be effective, in a jump takeoff rudder authority is limited, so the engines are placed very close to the centerline to minimize the yawing moment. The vertical thrust line of the engines is also near the center of gravity, so the fuselage necks down at the rear allowing the engines to be placed at the proper location.
Record Breaking Variant
A specially equipped version of this aircraft with larger engines and fuel bladders will be used for very high speed research and to dramatically set the rotorcraft speed, altitude, and range records all in a single flight. From a jump takeoff in LA , the aircraft would fly nonstop, non-refueling over 5000 nm to the Farnborough Air Show, at ~5300 miles, or the Paris Air Show, at ~5800 miles (official record is 2211 miles set in 1966). At that point, fuel and weight would be low enough to fly above 50,000’ (official record is 40,822’ set in 1972) and 450+ kts (unofficial max speeds include the Airbus X3 at 255 kts set in 2013, and the Bell 533 at 275 kts set in 1969). The flight would end with a zero roll landing. This aircraft could also break the climb to altitude record for rotorcraft.
