SJ30-2 Reaches Mach .83 In Test Flight

Sino Swearingen Aircraft Corporation execs are all smiles as the company accelerates its FAA certification program of the corporate SJ30-2 twinjet. The aircraft is undergoing high-speed flight testing to maximum operating speeds (Vmo/Mmo). Production model S/N 0002 flew to one of its highest speeds ever, Mach .83 (558 mph) in level flight during high-speed envelope expansion tests three weeks ago. A Hawker Hunter 58 -- a high-altitude supersonic fighter -- was used as the chase plane.

Chief Test Pilot Carroll Beeler was at the controls of the SJ30-2 during the tests. In a company press release, Beeler, a former Navy jet fighter pilot, stated, "Envelope expansion was completed with no problems at all. The high-speed points to .83 Mach (558 MPH) were flutter free, stable and matched all predictions."

Sino Swearingen's SJ30-2 business jet is a high-performance, seven-place twinjet aircraft with a 2,875-statute-mile NBAA IFR range (2,500 nm). According to Sino Swearingen, the SJ30-2 will cruise at speeds in excess of Mach .80 and operate at altitudes up to 49,000 feet, and will maintain a "sea level cabin" to 41,000 feet with the highest pressurization differential in the business jet world: 12.0 psi. The SJ30-2 will be certified for single-pilot operation.
