The resulting stiction can temporarily prevent the rotor from turning when only the force of ram air is applied to the core.
Ramjet motors are also usually fitted with turbopumps, the turbine being driven either directly by external freestream ram air or internally by airflow diverted from combustor entry.
Ramjet turbopumps use ram air expanding through a turbine.
The bleed air is cooled in the heat exchanger by ram air entering the dorsal fin inlet and passing through the heat exchanger.
A prototype constant speed propeller was developed for the aircraft using differential between engine oil, and ram air pressure to control pitch.
The cooling air filter was mounted below the steering head (between the forks) to provide a partial ram air effect.
Healthy torque, ram air, and a stout suspension meant muscle was still alive in the 1971 Buick GS 455.
Conventional traction kites use either a rigid frame inflated with a pump prior to launching or ram air inflated cavities.
Smaller inlet tubes provide ram air to pressurize the fuel tanks.
Such effects are typically only felt at very high speeds, making ram air primarily useful for racing, not street performance.
