The principle of work of the floating landing platform that the present embodiment provides is:
Before fixed wing aircraft landing, first make the two output shaft electric machine of startup, make the speed of accelerating pulley be more than or equal to the landing of fixed wing aircraft time speed, and the direction of the linear velocity on the summit of accelerating pulley is identical with the sense of motion of fixed wing aircraft, now accelerating pulley is in idling conditions and does not contact with cylinder, the position of floating platform does not change, when fixed wing aircraft kills engine, when braking and aim at the level point landing on floating platform, rub between fixed wing aircraft and the upper surface of floating platform, produce interactional power, floating platform is subject to an application force forward, and by the roller mechanism that floats, floating platform is floated forward, floating platform then makes roller bearing vertex motion to the groove bottom of the second half grooves from the nadir of the groove bottom of the second half grooves, afterwards accelerating pulley is made to contact with cylinder, cylinder then blocks accelerating pulley and travels forward, such accelerating pulley is just in friction of rolling state with cylinder, accelerating pulley drives cylinder to rotate together, finally release the kinetic energy of floating clouds platform, floating platform also can not continue to float forward,
When after the disappearance of application force forward that floating platform is subject to, under the effect of the gravity of floating platform, floating platform orders about the nadir motion of roller bearing to the groove bottom of the second half grooves, floating platform also backward float self-return, therefore, achieve that fixed wing aircraft completes without blocking on floating platform, the object of pinpoint landing.It should be noted that, the utility model is applicable to fixed wing aircraft and lands on aircraft carrier, can also be used on amphibious assault ship, the ground attack aircraft of fixed-wing and light fighter is made to amphibious assault carrier landing, greatly promote the ability of amphibious warfare, also the situation that when fixed wing aircraft lands on land, runway is shorter is applicable to, also the emergent landing of the aircraft of alighting gear fault is applicable to, when there is alighting gear fault in the aircraft landed, use ventral lands, ventral drops on floating platform and can not rub for a long time with runway, greatly improve the safety factor of forced landing aircraft.
In sum, the floating landing platform that the utility model embodiment provides specifically has following advantage:
1, applied widely, as long as the speed of the size of floating platform, load-bearing and accelerating pulley can meet, any type can realize without blocking landing.
2, there is higher reliability, compared with arresting gear, there will not be and leak the phenomenon such as extension, disconnected rope.
3, the difficulty of the landing of fixed wing aircraft can effectively be lowered, aviator goes around without the need to being ready at all times, and only need operate according to normal landing procedure, reduces aviator and to land manipulation difficulty, be conducive to focusing one's attention on, make the perception to environmental information that aviator keeps good.
4, have stronger highly versatile, as long as within the carrying scope of floating platform, do not limit type, most aircraft can land thereon, and carrier-borne aircraft is without the need to installing landing hanging cable system additional, and making aircraft carrier carry type has had selectivity widely.
5, can with type aircraft carrier deck smooth connection, deck surface does not totally have unnecessary thing, type aircraft carrier deck can be made to keep complete, through, voluntarily or can be drawn by tractor truck after carrier-borne aircraft landing and sail out of, rescue, guarantee, duties vehicle and personnel can directly enter, and eliminate the safety hazard of check cable recessiveness.After the floating landing platform using the utility model to provide, aircraft carrier is without the need to using angled deck, and avoid the runway centerline difficulty that continuous displacement brings to landing because aircraft carrier moves ahead of angled deck, variable inclination deck is straight-through deck, two, the end.
6, take type aircraft carrier deck space few, save the expensive real estate of type aircraft carrier deck, enable that type aircraft carrier deck space is more effective to be utilized, the carrier aircraft quantity of aircraft carrier can be improved.
7, can easily with the integration of aircraft carrier original system, only need increase a control system and be used for manipulating the unlatching of this programme and stop, the signal in original system, mark, prompting, command echelon all can directly use.
8, use conveniently, without folding and unfolding reciprocation cycle compared with arresting system, can uninterruptedly directly use, utilization ratio is high.
9, structure is reliable, and maintaining is convenient, does not have complicated hydraulic pressure, pressure system compared with arresting system, and control system is also very simple, and serviceability is high, is easy to maintaining.
10, there is more wide utilization space, airport, ground can be used in, improve the runway degree of utilization on airport, ground; May be used for the emergent landing of airport, ground to breakdown plane; The resistance that may be used for ground airfield runway stops, and prevents the accident that aircraft guns off the runway.
