Summary: | AFTER having lived in a world of false security for many years, the aeronautical industry has finally begun to recognize its need for a satisfactory air filter in its engines. This awakening has been due largely to the present war, which is requiring that airplanes be operated from all kinds of fields in every part of the world. Desert warfare demands efficient carburetor air filters even for only a few hours of successful operation of an airplane. In this paper Mr. Cannon discusses, with the help of illustrations, various makes of filters, including a crude but ingenious desert-made airscoop, a none-too-efficient German filter used on the Messerschmitt 109, and various installations designed in this country. Our designs are quite different from the British and German ones, because we were able to take advantage of the extensive development work of the automobile and air conditioning industries. One type of filter was found especially easy to adapt to aircraft. It was the viscous impingement filter, which is capable of very efficient operation. The author has also included descriptions of a number of installations using the viscous impingement filter, which are believed to give the engine the protection it needs against damage by sand, with the least complication and the least added weight, without upsetting the carburetor metering, and without imposing any added duties on the pilot. |
