Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
The first in the series, the LM-1 was first flown in 1985. The aircraft are sold as plans, with components or complete kits also available to speed construction time. [1] [2] [3] All aircraft in the series feature enclosed cabins allowing year-round flying, docile handling characteristics and a 300-hour construction time. [2]
Engines can be fitted with power ratings from 90 to 180 hp (67 to 134 kW) (some say 65-125 hp), [3] weighing up to 310 lb (141 kg), enclosed in a fibreglass cowling. A sliding canopy covers the cockpit, the landing gear uses some landing gear components from the Wittman Tailwind and conventional controls are fitted but with an all-flying ...

The standard engines used are the 180 hp (134 kW) Lycoming O-360, modified with high compression pistons, an inverted oil system and fuel injection or the 160 hp (119 kW) Lycoming AEIO-320 powerplant. [1] The aircraft has an empty weight of 740 lb (340 kg) and a gross weight of 1,150 lb (520 kg), giving a useful load of 410 lb (190 kg).
Main piston engined production kits with wings extended to 21 ft 6 in (6.55 m). Kits still available in 2011. [31] BD-5D Factory built versions of the BD-5B. BD-5G Piston-engined production kit with wingspan of 17 ft (5.2 m) and a gross weight of 660 lb (299 kg). Kits still available in 2011. [31] BD-5J Jet powered version.
The design is a four-cylinder, two-stroke, piston diesel engine, in an inverted-V configuration, with turbocharging and supercharging, mechanical fuel injection, liquid cooling, direct drive. It can run on Jet-A or sustainable aviation fuel. The manufacturer claims that it has "40 percent fewer moving parts than other engines in its category ...
The Pitts Model 12 (also known by its nicknames "Bolshoi," "Macho Stinker," and "Pitts Monster"[1]) is a high-performance [2]) aerobatic biplane designed around the Vedeneyev M14P/PF Russian engine. The aircraft can be built from plans or as a kit plane , or bought ready-to-fly from the factory.
