An Auxiliary Power Unit (APU) doesn't provide thrust because its primary function is to generate electrical power and pneumatic pressure for aircraft systems while on the ground or during engine start. The APU operates independently of the main engines, which are specifically designed to produce thrust for propulsion. Instead, the APU supports systems like air conditioning, lighting, and engine start without contributing to the aircraft's forward motion. Its role is crucial for operational efficiency rather than propulsion.
