Is the Canair a quiet craft when operating?
A – Not exactly. If the definition of quite is to compare it to a modern automobile, then defiantly NO. If compared to a light aircraft, then YES the Canair is quiet. The noise from a Canair hovercraft comes from 1. The fan, 2. The engine exhaust, 3. The engine block and the structure on which it is mounted and 4. The air intake of the engine. The fan is 31″ diameter with nine to twelve, wide cord blades for minimum noise generation. The exhaust system needs to be matched with the engine for maximum noise suppression. The engine block is rigidly secured to a mounting plate which in turn is secured to a frame which is then mounted on resilient rubber mounts to lower noise transference. The final source of noise is the air intake to the engine, which should be fitted not only with a good air filter but also an air intake silencer.
