JGHT International, 3 October 1963 591 ajlable immediately on the return of the oe-expired unit. In the event of a prema- re failure a replacement engine will be spatched immediately to the operator at location of the failure. A pool of rviceable engine accessories will likewise available, and Bristol Siddeley will also Id stocks of maintenance spares with rwork Corp. Ihe scheme also covers assistance and vice from Bristol Siddeley service engin es, one of whom will be accredited to each itributor. In addition, it embraces the ntinuous emergency service direct from factories; free training of pilots and 3und crew, either in the United States at Bristol Siddeley's own training school; d free provision of all relevant written iterial. By charging for overhauls on a ed price per engine hour basis, a Bristol ideley warrant of quality is given, on the mplete engine, for the whole of its life. The Viper 521—the production version the Viper 20 civil variant designated for : DH. 125—has an ISA take-off thrust 3,1151b. The engine is flat-rated, and thus lintains a larger proportion of this thrust hot or high-altitude conditions than mid a normally rated engine. For example, ISA + 10°C, the thrust falls by only me 1201b. Vipers have proved robust and iable during some 250,000 flying hours, andling characteristics are excellent and ere is a quick response to throttle move- ents, allied to a re-light capability up to nsiderable altitudes. Basically a very nple engine, the Viper is less likely to ffer from foreign-body ingestion, or ice mage, than are many of its contempor- ies. All requirements for civil certification, eluding the anti-icing system,, have been eluded in the design. nMis' Test Pilot Mr John J. Mason, rmerly with British United Air Ferries, s been appointed a test pilot with Smiths 'iation Division, joining the company's ing unit at Staverton Airport, Chelten- m, Glos. Aged 28, he has some 3,500hr ing experience on jets and piston-engined P«. holds an ALTP and flight navigator's wee and is an Upper Freeman of WAN and a member of the Institute of v|gation. eMTech DCS Representation Data- totrol Systems Inc of Danbury, Conn, toufacturers of research instrumentation Mucts and systems, have appointed Wech Ltd, London (Heathrow) Airport, sunslow, Middx, representatives for the ftpam's products and services in the ™*d Kingdom. Data-Control Systems Inc, it is stated, "ers a complete line of products and Jems for the acquisition, storage and action of data from remote locations, ocularly adapted to research in aero- J*' nuclear and related industries. DCS Petence and equipment span all forms ata encoding and modulation-ampli- tv'hIeqUency and Pulse- Dcs systems • •* single-channel or multi-channel, Woej multiplexed or time-multiplexed. e area of frequency multiplexing, DCS has pioneered the use of constant band width subcarriers which enable many channels of data to be transmitted or recorded and reproduced in synchronism. Equipment for airborne modulation, trans mission and recording and for reception and reduction of data on the ground is manu factured in variety by DCS. DCS digital data products and systems were developed in time to reach the market created by the vast amount of data collected by research satellites." FieldTech, a member of Hunting Light Industries Ltd, is currently engaged in sales promotion of the technical products and systems of several British and US manufacturers. USA F-lll Escape System The new F-lll tactical fighter's two-man crew will be provided with the most advanced escape and survival protection system yet devised, according to a release from the US Air Force Systems Command's Aeronautical Systems Division, Wright-Patterson AFB, Ohio. McDonnell Aircraft Corporation is de veloping the system. General Dynamics/ Fort Worth is prime contractor for the fighter. Should emergency escape become neces sary, the crew will take the entire crew compartment with them. This new tech nique calls for literally cutting the compart ment away from the aircraft fuselage. The compartment will be severed in front of the instrument panel bulkhead, beneath the cabin deck, and just behind the crew seats. A portion of fuselage and wings will be included to provide in-flight stability. Escape sequence begins with activation by either pilot or co-pilot. Two actions happen simultaneously. A linear shaped- charge, described by ASD engineers as an "exploding wire," installed along the entire area of the escape pod, will detonate. At the same time the escape-pod rocket motor will ignite. The charge will cut through supporting metal much like a welder's cutting torch; meanwhile the rocket motor will develop sufficient thrust to propel the crew compart ment clear. The crew will be safely separated with adequate environmental protection and all survival equipment. An emergency radio transceiver will start broadcasting automatic ally. The pod's recovery system will consist of two parachutes, a small drogue chute deployed to decelerate the pod during high speed ejection, and a main parachute. To lessen landing shock, an absorbing material will be attached to the bottom of the pod. This escape system, it is claimed, will enable the F-l 11 crew to abandon the air craft at any altitude and speed condition, including zero altitude and zero speed, or even under water. Manufacturing Gyroscope Bearings Bear ings made of synthetic jewels material and said to be the tiniest ever manufactured in the United States are being made at a factory in Rolla, North Dakota, operated by the Bulova Watch Co. They are for Litton Systems Inc, for use in a gyroscope in a flight control system. The factory forms the Turtle Mountain division of the Bulova Co and is said to be the only one of its kind in the US. The general manager, Mr Warren H. Young, stated that the disc-shaped bearings are 0.005in thick and have an outside diameter of O.OlOin, no more than three times the diameter of human hair. He added that it would take more than 400,000 of them to fill a level teaspoon, and although they are priced at only 20 cents each, a pound of them would cost $3m. Although the bearings are similar to the type used in fine timepieces, the factory's production is for specific space and defence projects and the government stockpile.
