The design was introduced publicly at the Flying Show in Birmingham in December 2011, where writer Demitri Delemarle reported that it "stole the show", due to its unusual semi-enclosed cockpit design.[1]

Design and development

edit

The PulsR was designed to comply with the Fédération Aéronautique Internationale microlight category, including the category's maximum gross weight of 472.5 kg (1,042 lb) with a ballistic parachute. The aircraft has a maximum gross weight of 472.5 kg (1,042 lb) with a ballistic parachute and 450 kg (992 lb) without.[1]

The design was first shown in 2011 and remained in prototype-only form until 2015.[1]

The aircraft design features a strut-braced topless hang glider-style high-wing, weight-shift controls, a two-seats-in-tandem semi-enclosed cockpit with a cockpit fairing and windshield, tricycle landing gear with main gear wheel pants and a single engine in pusher configuration.[1]

The aircraft fuselage is a monocoque design made from composite carbon fibre, with its double surface wing covered in Dacron sailcloth. Its 9.26 m (30.4 ft) span wing is supported by struts and uses an "A" frame weight-shift control bar, which is routed through the open side window spaces in the semi-enclosed fairing. The powerplant is a four-cylinder, air and liquid-cooled, four-stroke, dual-ignition 100 hp (75 kW) Rotax 912ULS engine.[1][2]

The aircraft has an empty weight of 251 kg (553 lb) and a gross weight of 472.5 kg (1,042 lb), giving a useful load of 222 kg (489 lb). With full fuel of 78 litres (17 imp gal; 21 US gal) the payload is 166 kg (366 lb).[1][2]

Operational history

edit

Writer Demitri Delemarle reports that the design "never fails to attract attention" wherever it is shown, due to its unusual aerodynamic cockpit design, which makes it much faster and gives a better glide ratio than other trikes.[1]
