There is a new entrant in the (slow) race to bring a supersonic business jet to market, Spike Aerospace. Headquartered in Boston, Spike Aerospace was founded by engineers and consultants with experience working at Airbus, Boeing, Eclipse, Gulfstream, the Jet Propulsion Laboratory and NASA. The Spike S-512 is targeting a Mach 1.6 cruise speed and Mach 1.8 maximum speed.
With an mtow of 84,000 pounds, the S-512 is designed to carry 40,000 pounds of fuel and fly 4,000 nm (reserve not specified). Engines are older technology, two 19,000-pound-thrust Pratt & Whitney JT8Ds. Balanced field length will be 6,000 feet and stall speed 105 knots.
The cabin length is 40 feet, with a 6.2-foot circular cross section capable of accommodating 12 to 18 passengers.
Spike Aerospace believes that it can deliver a market-ready version of the S-512 five to seven years after formal program launch, and the company is seeking investors and hiring engineers.
