- Direct Mount: In a direct mount, the engine is attached to the aircraft structure using a series of bolts or screws. This type of mount is typically used for small, lightweight engines that do not produce a lot of vibration.
- Vibration Isolated Mount: A vibration isolated mount uses isolators to reduce the amount of vibration that is transferred from the engine to the aircraft structure. This type of mount is typically used for larger, more powerful engines that produce a lot of vibration.
- Gearbox Mount: A gearbox mount uses a gearbox to reduce the engine's speed and increase its torque. This type of mount is typically used for turboprop engines, which operate at a much higher speed than piston engines.
- Linkage Mount: A linkage mount uses a linkage to connect the engine to the aircraft structure. This type of mount is typically used for engines that are mounted in a remote location, such as the tail of an aircraft.
