An improved method of calculating the performance of an airscrew has been described in prcv:ious reports (Refs. I and 2), which includes an allowance for tip loss. The present report contains tables of a parameter (x) ...

The generalised relations for shock, strong detonation and Chapman-Jouguet detonation waves are used to determine the flow variables behind an attached conical shock wave. The non-linear ordinary differential equations of ...

A large number of take-off tests have been made on a Comet aircraft with the object of (a) acquiring comprehensive data on undirected take-offs; (b) testing a SCAT take-off director. SCAT is explained in detail and the ...

Investigations into porpoising stability, water resistance, and seaworthiness have been made on the hull design of the E6/44. The original lines were unsatisfactory for seaworthiness and porpoising stability at overload ...

A technique is presented for condensing a multi-degree-of-freedom flutter calculation so that similar flutter conditions are achieved with two degrees-of-freedom. Use is made of digital computer programmes, and the process ...
