Development of German Aircraft Engines

Although considerable improvement in flying efficiency may safely be expected, on account of the low unit weight of the above-named engines, the light-weight engine is not, in itself, a perfect aviation engine, as the latter would be required to supply consistently uniform power up to those altitudes in which the greater part of its existence is spent.

The Handley Page Wing Patent

The following is an abstract of United States Patent No. 1,35,666 granted September 21 to F. Handley Page. This is the wing device that has been the object of much secrecy and discussion this year.

Editorials

THE sixth race for the Gordon Bennett Aviation Cup, which resulted in the victory of the French defending team and France’s permanent holdership of the famous trophy, should teach us a valuable lesson. It is generally conceded that the American entries for the Gordon Bennett aviation race are faster machines than the French types which finished first and second.

The Dayton-Wright R.B. Racer

The Dayton-Wright entry in the Gordon Bennett race shows a decided departure from the usual type of aircraft in the way of wing and landing gear construction. The two-fold purpose in designing this racer was: first, to bring the Gordon Bennett cup back to America, and, second, to offer to the aviation world something new in airplane construction and performance.

Turn and Pitching Indicators for Airships

As is well known, the usual line of flight of an airship curves constantly in both vertical and horizontal planes. The big envelope is continually yawing and pitching, and the extra fuel consumed in reaching a destination by this winding route is a very material fraction of the total amount used.

The Westland Six-Seater

This British machine is similar to the Westland Limousine in construction, but is larger. It is fitted with a tail trimming gear so that no ballast is necessary. For heating in cold weather, there is a heating box alongside the center exhaust manifold which introduces hot fresh air into the diffuser box.
