SUMMARY
The thrust-to-power (F/P) ratio for modern propulsion systems varies significantly across different vehicle types. For instance, the F/P ratio for a DC-9 jet engine is approximately 0.016 N/W. This ratio is not static and changes with vehicle speed, particularly for propeller-driven aircraft, where efficiency fluctuates with airspeed. Understanding these dynamics is crucial for evaluating propulsion efficiency across various mechanical drive trains, including cars, trucks, boats, planes, and rockets.
