Teams responded to a Statement of Work for a remotely piloted sport jet and trainer designed around an unmodified Kingtech K45 turbine engine. Wingspan but be equal to or less than 53" to allow shipping. Minumum dry weight of the trainer configuration must be 12 lb. Teams must submit a cost bid for building 100 aircraft and compete in aerobatic performances in a competition in the style of the France Air Show, while simultaneously running a static display of the aircraft. Design objectives were to optimize ease of operation, pylon racing ability, max/min airspeed ratio, max airspeed, short takeoff and landing, along with several others.

Specification List: 
 Wing:
  • wingspan = 53 in.
  • wing area = 556 sq. in.
  • taper ratio = 0.72
  • airfoil = MM 1100 (modified)
  •     Fuselage:
  • length = 60.5 in. 
  • max width = 5 in.
  • max height = 7in.
 
    Propulsion:
 
  • engine = Kingtech K45 Axial Turbine
  • thrust = 9.9 lbs @ 15 C
  • max RPM = 162,000
  • max exhaust gas temp = 700 C
  • fuel = Diesel, Jet A1, or Kerosene
 
    Weights:
  • Structural = 8 lb
  • Dry = 12 lb
  • GTOW = 14.2 lb
 
    Performance and Features:
  • max speed = 180 mph
  • min speed = 30 mph
  • Operates on 200 ft runway
  • Composite fabrication
  • Spar tested over 50G
  • Inverted Y tail for high alpha maneuvering
  • Ceramic painted tail
  • Removable wing
  • Sleek, low drag design
