Faire4 flies the first Vertical Take-off Airliner Adding achievement to achievement, Fairey Aviation have now built potentially the most important transport aeroplane in the world, the Fairey Rotodyne. Carrying 48 passengers or 41 tons of freight it takes ofT vertically as a helicopter and having gained height flies forward as a normal twin-engined airliner. It is the most adaptable rotary-wing aircraft in the world and the first to offer operating economy directly comparable to that of fixed-wing aircraft over ranges of up to 400 miles. The arrangement within the Rotodyne's capacious fuselage can readily be adapted to suit civil or military applications. Powered by two Napier Eland propellor-turbines with Fairey Pressure-Jets at the rotor-tips Jor take-off and landing. 48 passengers . 185 m.p.h. cruising speed otodyne 400 miles maximum range.

These meetings were followed up by friendly visits to R.A.F. stations, and one fact which soon became clear was the eventual necessity for air-to-air radar, homing devices and elec trical equipment which would be indepen dent of altitude. Yet the design of much of this equipment was only beginning, and if full provision had been made for it in the S-R.53. it would have been out-of-phase with the time scale. Thus, late in 1953 and in parallel with the design and construction of the S-R.5~. Saunders-Roe began to design a direct development ofthisaircraft. This was known as the S-R.I77. Proposals for this very advanced inter ceptor were placed before the Ministry of Supply in 1954, and the design contract for this aircraft was finally received in 1955. Unless there is a sudden change of Government policy the S-R . I77 will not be built. and The S-R.I77 is aerodynamically similar it is to be regretted that this interesting design has been shelved owing to lack of funds to the S-R.53, the ma in difl'erences being in and foreign orders. The history of the development of the 177 is in itself of interest. and its armament, interception equipment and it is published here by kind permission of Saunders-Roe. automatic pilot equipment. In addition, by combining the cruising economy of a much more powerful turbojet with the great high altitude thrust of the Spectre, it ca n make much wider use of the advantages of the The Saunders-Roe mixed power formula than can the lower powered S-R.53 . The basic ideas which led to this Saunders S-R.177 Roe mixed unit conception are simple. An interception operation calls for the aircraft to perform a flight sortie that involves THE story of the S-R.I77 began when were considered, and it was obvious from periods of low and medium speed flight and Saunders-Roe started a serious study of the start that the choice of the oxidant to be also calls instantly for high acceleration and aircraft for combat at extremely high alti used was a vital factor.
