FLIGHT International, 26 April 1962 Bristol Siddeley Pegasus Blackburn Cumulus for the Short Belfast. The Palouste has been applied to the Douglas DC-8 and Boeing 707 and to the Canadair CL-66. The Cumulus has been selected as the airborne auxiliary powerplant of one of the latest strike aircraft for the RAF. Burndept Ltd Under the trade name of "Kalium" the Burndept- Vidor Group have developed a range of primary electrical cells based upon one of the most efficient practical electrochemical couples known: zinc/potassium-hydroxide/mercuric oxide. Among the many advantages of such cells, Burndept emphasize the follow ing : under most conditions, capacity from four to seven times that of a conventional dry cell of similar size; substantially constant volt age (nominal e.m.f., 1.34V ±5mV) during discharge; ability to sustain relatively high current drains; capacity not appreciably affected by intermittent use (shelf-life at least a year at normal temperatures); and the possibility of storage at up to 50°C (122°F) with little adverse effect. Multi-cell groups may be potted in epoxy resins, and Kaliuffl cells are available from stock in cylindrical, button or box forms with nominal capacities ranging from 0.28 to 2.5A-hr. The characteristics of these cells have proved very suit able for electronic equipment of all kinds, and especially in such applications as guided weapons, where power supplied for compact and complex circuits must be "small, accurate and stable." Burndept will also be showing their new fully transistotized VHF/UHF recovery beacon, claimed to meet all current NATO and foreign air force requirements for personal wear or dinghy stowage. It is also suitable for civil aviation and marine applica tions. Known as the Search and Recovery Beacon Equipment BE 301—SARBE for short—it weighs 21b 2oz complete with a mercuric oxide battery giving 48hr endurance at 4°C. In addition to recording homing ranges of up to 90 miles during trials with an aircraft flying at 10,000ft it has successfully undergone such en vironmental tests as a simulated descent from 70,000ft in 5min. Decca Navigator Co Ltd This company will be displaying Decca Navigator, Harco and Doppler equipment and pictorial presen tations of various types on two stands. Harco, the Decca Navi- Installing one of the two de Havilland Gnomes which power the Westlond Wessex 2 helicopter for the Royal Air Force gator international development, is being shown on the stand shared with Telefunken. The Omnitrac computer, a second example of which is now reported to be flying, will be included, as will the Mk 3 self-setting Flight Log which is coupled with it in the Harco system. Telefunken are working on development of the Harco presentation and on the associated data link. CSF in France are also taking part in the Harco consortium. On stand 1705, Decca are showing their type 62 Doppler radar, recently ordered as standard equipment for BEA's Tridents. In this installation it will be combined with a pictorial navigation presentation in the centre of the main instrument panel. This marks something of a new departure in pictorial navigation in civil aircraft. Also on show will be some of the various types and sizes of Roller Map, developed by Decca in recent years as navigation aids for single-seat aircraft. It has recently been announced that the Buccaneer, Scimitar and Sea Vixen will have Roller Maps, some purely DR devices and others driven by Doppler radar.
