Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races. Aircraft equipped with contra-rotating propellers (CRP) [1] coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra ...
The exhaust ports of a NK-12 in an outboard nacelle on a Tu-95. The Kuznetsov NK-12 is a Soviet turboprop engine of the 1950s, designed by the Kuznetsov design bureau.The NK-12 drives two large four-bladed contra-rotating propellers, 5.6 m (18 ft) diameter (NK-12MA), and 6.2 m (20 ft) diameter (NK-12MV).
The Westland Wyvern is a British single-seat carrier-based multi-role strike aircraft built by Westland Aircraft that served in the 1950s, seeing service in the 1956 Suez Crisis. Production Wyverns were powered by a turboprop engine driving large and distinctive contra-rotating propellers, and could carry aerial torpedoes.
They drove a series of eight paired contra-rotating propellers, which were set on four forward-facing nacelles. [ 1 ] [ 8 ] The Brabazon Report had assumed that the wealthy people flying in the aircraft would consider a long trip by air to be uncomfortable, and so designed the Type I for luxury, demanding 200 ft 3 (6 m 3 ) of space for every ...
The XT40 installation on the Skyshark used contra-rotating propellers to harness all the available power. Wing root thickness decreased from 17% to 12%, while both the height of the tail and its area grew. [3] Engine development problems delayed the first flight until 26 May 1950, made at Edwards Air Force Base by George Jansen. [3]
The resulting T40 combined two Allison T38-A-1 power sections side-by-side with a common reduction gearbox powering contra-rotating propellers. Similar in layout to the Armstrong Siddeley Double Mamba , the T40 differed in that each engine drove both the forward and the rear propellers, unlike the Double Mamba, where each Mamba power section ...
The XFV was powered by a 5,332 hp (3,976 kW) Allison YT40-A-6 turboprop engine driving three-bladed contra-rotating propellers. The tail surfaces were a reflected cruciform v-tail (forming an x) that extended above and below the fuselage. The aircraft had an ungainly appearance on the ground with a makeshift, fixed landing gear attached. [3]
It was a large high-wing flying boat with Allison T40 engines driving six-bladed contra-rotating propellers. It had a sleek body with a single-step hull and a slender high-lift wing with fixed floats. The Navy ordered two prototypes on 27 May 1946. Designated XP5Y-1, the first aircraft first flew on 18 April 1950 at San Diego. In August the ...
