The VSR SR-1 Snoshoo (English: Snowshoe) is an American homebuilt Formula One racing aircraft that was designed by Alan VanMeter and A.J. Smith and produced by VanMeter Smith Racing (VSR) of Wichita, Kansas. It was designed in 1993 and first flown in 1997. The aircraft is supplied in the form of plans for amateur construction, with some key parts available to speed construction.[1][2]
Design and development
The SR-1 Snoshoo features a cantilever mid-wing, a single-seat enclosed cockpit under a bubble canopy, fixed conventional landing gear with wheel pants and a single engine in tractor configuration.[1]
The aircraft fuselage is made from welded 4130 steel tubing covered in carbon-fiber-reinforced polymer fairings ahead of the wing and doped aircraft fabric aft. Its 19.91 ft (6.1 m) span wing is made from Sitka spruce wood, has no flaps and has a wing area of 66.00 sq ft (6.132 m2). The cockpit width is 22 in (56 cm). The acceptable power range is 95 to 100 hp (71 to 75 kW) and the standard engine used is the 100 hp (75 kW) Continental O-200A powerplant, as required by the Formula One rules. The aircraft is stressed to +/-8 g[1][2][3]
The SR-1 Snoshoo has a typical empty weight of 530 lb (240 kg) and a gross weight of 760 lb (340 kg), giving a useful load of 230 lb (100 kg). With full fuel of 6 U.S. gallons (23 L; 5.0 imp gal) the payload for the pilot and baggage is 200 lb (91 kg).[1][2]
The designers estimate the construction time from the supplied plans as 1500 hours.[1]
Operational history
By 1998 the company reported that 20 kits and sets of plans had been sold.[1]
In March 2014 one example was registered in the United States with the Federal Aviation Administration.[4]
