“Vortech Kestrel Jet”的意思、由来-开放百科全书

The Vortech Kestrel Jet is an American tip-jet helicopter that was designed in the 1980s. Kits for amateur construction were originally provided by Vortech and plans remain available.^[1]^[2]^[3]^[4]

Design and development

The aircraft was designed to fit into the US FAR 103 Ultralight Vehicles rules, including the category's maximum empty weight of {{convert|254|lb|kg|0|abbr=on}}. The aircraft has a standard empty weight of {{convert|175|lb|kg|0|abbr=on}}. It features a single main rotor, a single-seat open cockpit without a windshield and skid landing gear. Power is supplied by two G8-2-20 rotor tip jets that run on propane, consuming {{convert|12|u.s.gal}} per hour and producing {{convert|47|lb|kg|0|abbr=on}} of thrust each.^[1]^[2]^[4]

The aircraft fuselage is made from bolted-together aluminum tubing. Its main rotor is {{convert|24|ft|m|1|abbr=on}} in diameter. Due to the lack of torque produced there is no tail rotor and instead the Kestrel mounts a circular-shaped rudder for directional control. Controls consist only of cyclic, rudder and throttle.^[1]^[2]
