ground roll वाक्य

The undercarriage consisted of a sprung monowheel, set well forward of the centre of gravity, and tail-skid, which improved stability on the ground roll during winch launching but raised the cockpit sill hampering boarding the aircraft.
After approximately 6, 000 feet ( 1, 800 m ) of ground roll, the airframe assumed a nose high attitude as it climbed to between 50 and 100 feet ( 30 m ), with one or more engines after firing excessively during the climb.
The use of a CCW system eliminates the need for large complex components in the free stream such as slats, greatly reducing the noise pollution of modern aircraft . Additionally, a much shorter ground roll coupled with steeper climb outs and approaches reduces the ground noise footprint.
In seismology, Rayleigh waves ( called " ground roll " ) are the most important type of surface wave, and can be produced ( apart from earthquakes ), for example, by ocean waves, by explosions, by railway trains and ground vehicles, or by a sledgehammer impact.
The asymmetric blade effect is dependent on thrust, and is proportional to forward velocity ( specifically CAS ) and, while generally insignificant during the initial ground roll for tail-wheel aircraft, will give a pronounced nose-left tendency during the later stages of the ground roll, particularly if the thrust axis is kept inclined to the flight path vector ( i . e . tail-wheel in contact with runway ).
