Abstract
Wave-off judgment research of carrier-borne aircraft in the landing process led by automatic landing system is made and the conception of security window in automatic Landing of the carrier-borne aircraft is proposed. Through the study of carrier-borne aircraft’s automatic safety window landing position, and calculates the boundary of safety window.
Highlights
The landing of carrier-borne aircraft is different from that of land-based aircraft
When the aircraft goes through safety window 15 sec far from the stern in automatic landing and if it cannot land within the ideal landing range under the guidance of ACLS, so at this time retrial flight should be in operation
Aircraft carrier air-wake model: Air wake’s effect on carrier-borne aircraft landing is caused by the air flow rate in the stern flow changes, so the air-wake model must be able to reflect the changes of the wind speed in and that of 5 sec, with vertical deviation from -9 to 9 m, in full automatic the path curve under the guidance of landing system
Summary
GUIDING SYSTEM caused by wave causes changes of the ideal landing point, filtering position changes of the ideal landing. When the aircraft goes through safety window 15 sec far from the stern in automatic landing and if it cannot land within the ideal landing range under the guidance of ACLS, so at this time retrial flight should be in operation. Roll spectrum transfer function: Fig. 6: Different longitudinal deviation path curve of carrier- This fitting method of simplifying carrier motion at sea power spectrum is very intuitive in use, simple. Aircraft carrier air-wake model: Air wake’s effect on carrier-borne aircraft landing is caused by the air flow rate in the stern flow changes, so the air-wake model must be able to reflect the changes of the wind speed in and that of 5 sec, with vertical deviation from -9 to 9 m, in full automatic the path curve under the guidance of landing system. The random carrier air-wake disturbance: Random atmospheric turbulence caused by the existence of aircraft carrier, power measurement of the spectra shows that this part of the atmospheric turbulence is anisotropic
