Flight data was collected for 24 landings on seven test : Stephen Corda. It was the purpose of the present investigation to define the subscale dynamic ground effects on the F S/MTD configuration in preparation for a comparison with the flight-test data when they become available.

A comparison of the dynamic measurements with the static wind-tunnel ground-effect measurements is also made.

ground effects. These difficulties associated with experimentation added to the generally benign nature of ground effects for conventional aircraft have limited the study of the dynamic ground effect problem.

Because ground effects tend to be more significant for low-aspect ratio aircraft, the phenomenon has. Ground Effect is a condition of improved performance encountered when operating near (within 1/2 rotor diameter) of the ground.

It is due to the interference of the surface with the airflow pattern of the rotor system, and it is more pronounced the nearer the ground is approached.

Pilots taking off from deep grass, or soft runways will often use ground effect to lift the airplane off the soft surface at a speed too slow to maintain flight out of ground effect. This reduces the resistance on the wheels and allows the airplane to accelerate to a higher speed before climbing out of ground effect.the portion of flight influenced by ground effect.

Although flight testing can obtain data in a more realistic dynamic scenario, the measurement process is still challenging. A fundamental limitation is that the airplane must be operated within a small range of vertical and horizontal velocities whenever it is in closeCited by:
