The wings are identical to the Bearhawk 4-Place Model B, employing the same Riblett 30-413.5 airfoil [5] and mounting flaps. [4] The aircraft's recommended engine power range is 250 to 315 hp (186 to 235 kW) and standard engines used include the 250 hp (186 kW) Lycoming O-540 , although the recommended engine is the 315 hp (235 kW) Lycoming IO ...
The Bearhawk was designed in the early 1990s [5] as a personal project by Barrows to carry aircraft engines for delivery as freight. It features a strut-braced high-wing, a four-seat enclosed cabin that is 42.5 in (108 cm) wide and accessed by doors, fixed conventional landing gear and a single engine in tractor configuration.
Inside of the tailcone of a Murphy Moose under construction, showing the semi-monocoque design. The Murphy Moose is a Canadian high-wing utility light aircraft produced in kit form by Murphy Aircraft of Chilliwack, British Columbia for amateur construction.
A section of the rear fuselage from a Vickers Warwick showing the geodetic construction in duralumin. On exhibit at the Armstrong & Aviation Museum at Bamburgh Castle.. A geodetic airframe is a type of construction for the airframes of aircraft developed by British aeronautical engineer Barnes Wallis in the 1930s (who sometimes spelt it "geodesic").
The pilot tries to perfectly balance a helicopter so that the fuselage remains horizontal in hovering flight, with no cyclic pitch control needed except for wind correction. Since the fuselage acts as a pendulum suspended from the rotor, changing the center of gravity changes the angle at which the aircraft hangs from the rotor.
The wing root fairing of an American Aviation AA-1 Yankee. An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag. [1]These structures are covers for gaps and spaces between parts of an aircraft to reduce form drag and interference drag, and to improve appearance.
Officials said an F-35 fighter jet crashed in Alaska on Tuesday after the pilot managed to safely eject from the aircraft – the latest mishap involving the U.S. military's most expensive weapon ...
Lifting line theory supposes wings that are long and thin with negligible fuselage, akin to a thin bar (the eponymous "lifting line") of span 2s driven through the fluid. . From the Kutta–Joukowski theorem, the lift L(y) on a 2-dimensional segment of the wing at distance y from the fuselage is proportional to the circulation Γ(y) about the bar a
