Oversold. Milward issued a statement passing the blame on to the Rolls-Royce Tyne engines that power BEA's 19 Vanguard propjets. Since mid-May, metal fragments have been showing up in the engine oil sumps, and they were found to come from compressor bearings. Pilots have had to call off flights just before takeoff because they have found oil pressure too low, and with as many as four Vanguards at a time in the shop for repairs, often due to a shortage of spare parts, the fault has had a snowball effect on BEA schedules. The newer three...
Once such joint ventures are arranged, the Indian government protects them against foreign imports by high tariffs and quota restrictions. Says Charat Ram, 49, whose combine of sewing-machine, refrigerator, air-compressor, textile, and chemical companies makes him India's eighth largest manufacturer: "You cannot make a loss unless you are an utter fool. We are absolutely in a seller's market...
...insult thousands of highly trained, intelligent Air Force ground crewmen who maintain our B-52s when you suggest that Cassius Clay [Feb. 25] could learn such a skilled job. The only thing he might be able to do is blow up a tire if the air compressor broke down...
Lift from a Plane. Because the basic ramjet is just about the simplest power plant ever to be airborne, its promise has always excited aeronautical engineers. Unlike the conventional jet, it has neither a complex turbine nor a compressor; it is an open-ended cylinder, known as a "flying stovepipe," with only fuel injection and ignition systems inside...
...test tube-from kerosene to peanut oil. Its basic works are uncomplicated. It sucks air through an intake and compresses it in a chamber into which fuel is sprayed and ignited by a spark plug (see diagram). The expanding gases drive one turbine wheel that spins the air compressor and then rush on to whirl another turbine that drives a shaft. Turbines in their simplest form have major disadvantages, but where these are not of prime importance, they are already hard at work. They run standby generators in telephone exchanges, drive an Army 13-car overland troop-supply train...
