ABOUT two years agoearly in 1928rumours first began to circulate that the Packard Company had built a successful aircooled radial Diesel engine which had satisfactorily completed flight tests.
IN the article Tendencies in Engine Design at Olympia published in AIRCRAFT ENGINEERING, September 1929 Vol. 1, pp. 247257, regret was expressed that there was no information available that D. Napier & Son, Limited were following up new ideas. It was admitted that the position of the Lion engine...
IT was not until about the year 1918 that any serious development of the fixed radial engine began in this country. In 1913, however, The Socit des Moteurs Salmson was formed in France to manufacture a stationary or fixed radial engine following experiments which were begun in 1908.
THE Siemens SH.20, which can be supplied with or without reduction gear, has a total swept volume of 315 litres and a power output of 500560 h.p., and is one of the largest and most powerful aircooled engines in the world.
THE design of aircraft instruments is a highly specialized art, and unless the principles are well understood a great wastage of time and money can occur before a successful instrument is evolved. The reasons for this will be clear after a consideration of the conditions which must bo satisfied...
THE possibility of sustained flight by heavierthanair machines was fully recognised during the last century by those who had studied the aerodynamic problems involved, and it was realised that its accomplishment awaited only the development of a prime mover of sufficiently light weight.
FOLLOWING the Air Convention held on the 13th of October, 1919, the I.C.A.N. International Commission for Air Navigation laid clown the minimum requirements for Airworthiness Certificates for Civil Aircraft, and the regulations for the testing and approval of type and series engines are the...
