CONSIDERATIONS of aircraft-engine installation singular to the inverted, in-line, aircooled type of engine are presented here in the light of current engineering development in this field. Items of this installation technique discussed are: cooling aspects, cowling arrangements, oil cooling systems, induction systems, engine mounts, and exhaust systems.
Much of the information presented is based upon experience gained from wind tunnel and flight tests with Ranger engines.
The application of design considerations discussed under the cooling aspects of the aircooled engine has been proved satisfactory in flight test operations.
Latest methods of treatment of these factors are described. Substantial advancement has been made in handling the ever-present cooling problem common to all types of engines. This has been achieved by applying the design knowledge gained through considerable wind tunnel and flight research.
