monocoque|ˈmɒnəʊkɒk|
[a. F. monocoque, f. mono- mono- + coque egg-shell.]
a. Aeronaut. A fuselage or other structure having an outer covering in the form of a rigid skin or shell designed to bear all or most of the stresses that arise; now esp. one without longerons or stringers (see quot. 1948). Also transf. Usu. attrib.
1914Sphere 3 Oct. p. ii/1 The very speedy monocoques of the French. 1919A. W. Judge Elem. Princ. Aeroplane Design vi. 98 The Monocoque Type of Body. This type of body..consists of a single shell, conforming with the outside shape of the body, and..so constructed that it can withstand all the stresses which it is called upon to bear, without the necessity for longerons or cross bracing members. 1935C. G. Burge Compl. Bk. Aviation 595/1 The ‘monocoque’ is becoming increasingly popular for both military and commercial aeroplanes. 1938E. W. C. Wilkins Aeroplane Design vii. 171 The monocoque fuselage..consists of a thin shell..built around a number of transverse rings or formers... These formers are placed at intervals of about 2 ft. or more in the case of a wooden monocoque, but are very much closer together in the case of the metal monocoque. 1948C. E. Chapel Aircraft Basic Sci. ii. 84/2 Monocoques may be divided into three classes (monocoque, semimonocoque, and reinforced shell), and different portions of the fuselage may belong to any of these classes. The true monocoque has as its only reinforcement vertical bulkheads formed of structural members... All stresses are carried by the shell or skin. 1951Engineering 2 Nov. 573/1 A wing of the thin-walled monocoque type. 1969K. Munson Pioneer Aircraft 1903–14 123/2 Late in 1911 the ideas of the Swedish engineer Ruchonnet, for a monocoque fuselage shell of moulded plywood, were applied by Armand Deperdussin's designer, Louis Béchereau. 1970New Scientist 12 Nov. 329/2 No longer would an airship need to have a metal fabric-covered skelton. Instead it could have a ‘monocoque’ structure—the strength would be in a stiff lightweight outer shell. 1971Daily Colonist (Victoria, B.C.) 6 June 25/6 Launched four years ago, she is of monocoque design—one shell, no ribs, no frame, smooth inside and out.
b. In a motor vehicle, an underframe and body built as a single rigid structure (or in racing cars as a number of box-like sections) throughout which the stresses are distributed. Usu. attrib.
1956Molloy & Lanchester Automobile Engineer's Ref. Bk. xviii. 2 All-metal bodies fall into two main categories, firstly those which are used in conjunction with a separate chassis frame and secondly which are of the type known as monocoque or unit construction. The former naturally require only body structure panels, whereas the latter, in addition, require many pressings to form a unit (underframe or subframe), which although ultimately part of the body, is [a] substitute for the chassis frame and has provision made for all necessary attachment points for the various mechanical units. 1961Costin & Phipps Racing & Sports Car Chassis Design v. 43 All these, plus the single transverse torsion bar and the telescopic dampers, pick up on the rear bulkhead of the monocoque. 1963Engineering 1 Feb. 181/1 GT cars featuring monocoque construction of laminated wooden box sections. 1968Daily Tel. (Colour Suppl.) 15 Nov. 29/2 Despite the terrible force of the impact, the integrity of the cockpit area was preserved by the immensely strong monocoque chassis of his car. 1969‘D. Rutherford’ Gilt-Edged Cockpit i. 15 With the whole of his body encased in the monocoque shell and no part of his face visible he was an anonymous figure... Already other cars were flashing past. 1973Terry & Baker Racing Car Design & Devel. vi. 129 Although the basic space-frame is a comparatively light structure, it requires a separate body and fuel containers, all of which are integral parts of a monocoque, so this tends to nullify any hoped-for weight advantage. |
