Although briefly evaluated as a fighter by the Royal Air Force, the MB2 was limited in design potential and never entered series production. ==Design and development== James Martin, broadly responding to Specification F.5/34 for a fighter using an air-cooled engine for hot climates, designed a fighter using the simple basic structure employed and developed in his earlier MB1. Constructed of steel tubing, the MB2 incorporated many detailed improvements which further simplified production as well as repair and maintenance. Powered by a special Napier Dagger III HIM 24-cylinder H-type engine of 805 nominal bhp, but capable of operation at 13 lb boost to give over 1,000 hp for takeoff, driving a fixed-pitch, two-blade propeller, the MB2 was capable of 300+ mph (480 km/h) speeds "on paper." The undercarriage was fixed but cleanly faired in two trouser-type fairings, the port one carrying the oil-cooler. A retractable undercarriage to improve performance was "in the works" when the design was abandoned. The fuselage lines were square cut and exceptionally clean, with almost constant depth from nose to tail. An unusual feature, at that time, was that the fuselage was slightly longer than the wingspan, a feature retained in later Martin-Baker designs, which contributed to good stability and control in yaw. One of the hallmarks of Martin-Baker designs was the simple but efficient installation of main systems. The clean and orderly cockpit was set well back, allowing a good view downwards behind the wing. A crash post was fitted, which automatically extended to minimise structure damage and injury to the pilot in the event of a nose-over landing. A small, tapered tailplane was mounted on the top of the fuselage well forward of the stern post, while the fin and rudder combination was roughly triangular in side elevation. This arrangement placed most of the effective rudder area below the tailplane, thus providing an adequate balance to the keel surface and assuring good recovery from spins. In initial MB2 configurations, there was no fin and the rudder was mounted on the fuselage but lateral stability was unsatisfactory, with the fixed fin added later. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Martin-Baker MB 2」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
