What is the cooling mechanism used in the Schweizer 300C helicopter?

The Schweizer 300C helicopter utilizes an air-cooled engine that also incorporates oil coolers for its cooling mechanism. Air-cooled engines rely on the flow of air to dissipate heat generated during normal operation, which is a suitable design for helicopters where weight and reliability are critical factors. The oil cooler enhances this system by cooling the engine oil, which not only aids in maintaining optimal operating temperatures but also helps to lubricate and protect critical engine components.

This combination reduces the risk of overheating and allows for more efficient engine performance while keeping the overall weight of the helicopter relatively low. Thus, the design reflects an effective and practical approach for small helicopters in terms of cooling efficiency and structural simplicity.
