A Novel Transmission System: Details of the Tubular Positive Engine Controls Invented by M. René Tampier Available to Purchase

THE Tampier system of control transmissions for aircraft was developed a year ago by Monsieur René Tampier, who formerly constructed Tampier aeroplanes at Boulogne‐sur‐Seine, near Paris. The system, which makes use of “ball lever joints” and “ball tube joints,” has been developed for engine controls and has been mounted on the new Bréguet “Bizerte” three‐engined, naval reconnaissance flying boat described on p. 183 of this issue, the first important multi‐engined machine to be so equipped. The system will be developed for flying controls and for bomb dropping gear.
