Semi-monocoque structure inside an aircraft's rear fuselage ARV Super2 with semi-monocoque fuselage. The term semi-monocoque or semimonocoque refers to a stressed shell structure that is similar to a true monocoque, but which derives at least some of its strength from conventional reinforcement. Semi-monocoque construction is used for, among ...
Both monocoque and semi-monocoque are referred to as "stressed skin" structures as all or a portion of the external load (i.e. from wings and empennage, and from discrete masses such as the engine) is taken by the surface covering. In addition, all the load from internal pressurization is carried (as skin tension) by the external skin.
This structure is typically considered to include the fuselage, undercarriage, empennage and wings, and excludes the propulsion system. [2] Airframe design is a field of aerospace engineering that combines aerodynamics, materials technology and manufacturing methods with a focus on weight, strength and aerodynamic drag, as well as reliability ...
The 2-32 design was started in 1961 and completed with certification under type certificate G1EA on 19 June 1964. [4] [6] The 2-32 is all-metal, with a semi-monocoque aluminum fuselage and cantilever wings of 57 foot (17.37 m) span. It has top-and-bottom divebrakes and an all-flying stabilator tail. [1] [3]
By contrast, a semi-monocoque is a hybrid combining a tensile stressed skin and a compressive structure made up of longerons and ribs or frames. [3] Other semi-monocoques, not to be confused with true monocoques, include vehicle unibodies, which tend to be composites, and inflatable shells or balloon tanks, both of which are pressure stabilised.
The Whitley holds the distinction of having been the first RAF aircraft with a semi-monocoque structure in its fuselage, which was built slab-sided to ease production. [2] This replaced the tubular construction method traditionally employed by Armstrong Whitworth, who instead constructed the airframe from light- alloy rolled sections, pressings ...
Their first successful design was the Roland C.II Walfisch (whale), a two-seat reconnaissance biplane. It had a semi-monocoque fuselage, skinned with two layers of long plywood strips glued at opposing diagonal angles around a mold and skinned with fabric both inside and outside. The fuselage filled the full gap between the wings, leaving the ...
It had a semi-monocoque fuselage of pod-and-boom arrangement with a large bubble-like front greenhouse, [1] a three-blade rotor, and quadricycle fixed landing gear replacing the earlier tricycle arrangement. [4] The production S-52-3 (HO5S-1) incorporated a downward sloping (anhedral) v-tail stabilizer. [6]
