The Sport Jet II is an American amateur-built aircraft that is under development Sport-Jet, Limited. Sport Jet was designed by Robert Bornhofen who licensed the intellectual property to Excel Jet. The aircraft is intended to be supplied as a kit for amateur construction.[2][3]
Design and development
The Sport Jet II features a cantilever mid-wing, a four-seat enclosed and pressurized cabin, retractable tricycle landing gear, a T-tail and a single jet engine.[2][3]
The aircraft fuselage is made from composites, with the wing fashioned from aluminum sheet. Its 34 ft (10.4 m) span employs a NACA 64-415 airfoil, has an area of 165 sq ft (15.3 m2) and mounts flaps. The standard engine recommended is the 2,200 lb (998 kg) thrust Pratt & Whitney Canada JT15D turbofan, although when under development by Excel Jet a Williams FJ33 4A was used. The engine is mounted in the aft fuselage and is provided air by two intakes, one on each side of the fuselage.[2][3][4][5]
The prototype aircraft's Federal Aviation Administration aircraft registration was cancelled on 4 June 2013.[6] By May 2017 the company website had been blanked and it is likely that the project has been cancelled.[7]
