Vynález umožňuje sledovanie stavu podvozka a spodnej časti draku lietadla v akýchkoľvek poveternostných podmienkach, v núdzových aj prevádzkových situáciách.The invention relates to a system for monitoring the condition of an aircraft landing gear by applying a wireless electronic visual system. The invention makes it possible to monitor the condition of the landing gear and the lower part of the airframe in any weather conditions, in both emergency and operational situations.
Doterajší stav technikyPrior art
Podvozok lietadla umožňuje pohyb lietadla na zemi a v neposlednom rade aj tlmí zaťaženie konštrukcie pri pristátí a umožňuje vytratiť nemalú kinetickú energiu, ktorú lietadlo tesne po dotyku so zemou stále má. Stav podvozka lietadla je signalizovaný jeho palubným systémom, ktoiý je vo väčšine prípadov spoľahlivý. Vyskytujú sa však situácie, keď posádka lietadla nemá istotu, či monitorovaný stav podvozka je zhodný so stavom skutočným. V takom prípade je nutné overiť vysunutie, alebo zasunutie podvozka priamym pozorovaním. To sa obvykle vykonáva tak, že pilot prelietava pred pristátím v malej výške okolo riadiacej veže a dispečer oznámi pozorovaný stav podvozka posádke lietadla. V prípade poruchy komunikačných prostriedkov medzi vežou a lietadlom je aj tento spôsob nepoužiteľný. O pristátí musí rozhodnúť prvý pilot a v takom prípade všetko závisí od jeho skúsenosti a intuície aké je skutočné, no nesignalizované vysunutie podvozka. Problém s podvozkom lietadla je vážna porucha, ktorá má bezprostredný vplyv na bezpečnosť letu. Porucha vysunutia podvozka pri pristátí môže spôsobiť neovládateľnosť stroja alebo požiar, ktoiý sa z podvozkových nôh ľahko môže preniesť do nádrží pohonných hmôt a do blízkosti kabíny, alebo priamo do nej. Pripúšťa sa, že k podobným situáciám však dochádza z približne cca dvadsaťtisíc príletov a odletov ročne (na stredne frekventovanom letisku) len v minime prípadov. Aj napriek tomu je veľmi žiaduce, aby posádky hlavne dopravných lietadiel mali (okrem štandardného monitorovacie systému stavu podvozka) aj nezávislý jeho elektronický monitorovací systém poskytujúci vizuálnu informáciu o stave podvozka a celej spodnej časti lietadla.The landing gear of the aircraft allows the aircraft to move on the ground and, last but not least, dampens the load of the structure on landing and allows you to lose a considerable kinetic energy, which the aircraft still has after contact with the ground. The condition of the aircraft landing gear is signaled by its on-board system, which is reliable in most cases. However, there are situations where the aircraft crew is not sure whether the monitored condition of the landing gear is identical to the actual condition. In this case, it is necessary to verify the extension or retraction of the chassis by direct observation. This is usually done by the pilot flying around the control tower at a low altitude before landing and the dispatcher notifies the observed condition of the landing gear to the flight crew. In case of failure of the communication means between the tower and the aircraft, this method is also unusable. The landing must be decided by the first pilot, in which case it all depends on his experience and intuition as it is a real but unsigned landing gear extension. The problem with the landing gear is a serious failure that has an immediate impact on flight safety. Failure of the landing gear to extend when landing can cause uncontrollability of the machine or fire, which can easily be transferred from the landing gear legs to or near the fuel tanks or directly into the cab. However, it is admitted that similar situations occur from approximately twenty thousand arrivals and departures per year (at a medium-sized airport) only in a minimum of cases. Nevertheless, it is highly desirable that the crews of mainly commercial aircraft have (in addition to the standard landing gear monitoring system) an independent electronic monitoring system providing visual information on the condition of the landing gear and the entire lower part of the aircraft.
Podstata vynálezuThe essence of the invention
Podstata vynálezu spočíva v tom, že monitorovanie stavu podvozka lietadla je umožnené aplikáciou bezdrôtového televízneho systému. Monitorovanie sa vykonáva bezdrôtovým prenosom signálu medzi vysielačom kamery a prijímačom monitora. Vynález umožňuje sledovanie podvozka a spodnej časti draku lietadla v akýchkoľvek poveternostných podmienkach v núdzových aj prevádzkových situáciách vo dne i v noci. Ku spodku lietadla je pripevnená kamera, ktorá je cez jej vysielač bezdrôtovo spojená s prijímačom monitora. Ten je umiestnený v riadiacej kabíne lietadla. Zorné uhly kamery umožňujú sledovať spodnú stranu draku lietadla a statické i pohyblivé predmety na nej sa nachádzajúce. Ide predovšetkým o podvozok lietadla, motory, ale taktiež klapky a krídelká na predných a zadných krídlach. Pri vhodne zvolenom type (širokouhlej) kamery možno sledovať všetko, čo sa nachádza v spodnej polosfére pod drakom lietadla. Požiadavka použitia navrhovaného systému v núdzových situáciách predpokladá jeho vybavenie nezávislým, počas prevádzky neustále doplňovaným zdrojom energie. To umožní udržiavať posádke lietadla prehľad o stave podvozka aj pri zlyhaní časti, alebo celku systému napájania lietadla elektrickou energiou.The essence of the invention lies in the fact that the monitoring of the condition of the aircraft landing gear is enabled by the application of a wireless television system. Monitoring is performed by wireless signal transmission between the camera transmitter and the monitor receiver. The invention makes it possible to monitor the landing gear and the lower part of the aircraft airframe in any weather conditions in both emergency and operational situations day and night. A camera is attached to the bottom of the aircraft, which is wirelessly connected to the monitor receiver via its transmitter. It is located in the control cabin of the aircraft. The viewing angles of the camera allow you to monitor the underside of the airframe and static and moving objects located on it. It is mainly the landing gear of the aircraft, engines, but also flaps and wings on the front and rear wings. With a suitably selected type of (wide-angle) camera, everything that is in the lower hemisphere under the airframe can be monitored. The requirement to use the proposed system in emergency situations presupposes its equipment with an independent, constantly replenished energy source during operation. This will allow the aircraft crew to keep track of the condition of the landing gear even in the event of failure of part or all of the aircraft power supply system.
