Closed-Circuit Equipment Use Use of closed-circuit equipment is especially desirable when aircraft are being serviced by the rapid-refueling method. Rapid refueling is used to reduce the ground time needed to refuel aircraft, particularly helicopters used in support of combat operations. Reducing ground time doesaccomplishes two things. First, it reduces the amount of time that the aircraft is a stationary target. Second, it cuts the time that ground forces are without air support. In spite of its major advantage in a tactical situation, rapid refueling is less safe than refueling with the engines shut down. Closed-circuit equipment is preferred because of its built in safety features. CCR prevents spills; prevents fuel vapors from escaping at the aircraft fill port; and prevents dirt, water, and other contaminants from entering the aircraft fuel supply during refueling. These factors contribute to safe ground operations by reducing the fire hazard and safe flight operations by protecting the quality of the fuel used. OPEN-PORT REFUELING Open-port refueling is refueling by inserting an automotive-type nozzle into a fill port of a larger diameter. Most of the Army’s fueling nozzles are designed for open-port refueling. Because the port is larger than the nozzle, fuel vapors can escape through the fill port during open-port refueling operations. Airborne dust and dirt, as well as rain, snow, and ice, can get into the fill port during refueling. This contamination lowers the quality of the fuel in the tanks and endangers the aircraft. Spills from overflowing tanks are possible in open-port refueling. Spills can be caused from the sudden power surge that occurs when pumping from another nozzle in the system stops pumpingis completed. This throws the whole push of the pump to the operating nozzle. Because of these dangers, rapid refueling by the open-port method is restricted to combat, vital training, or testing use. http://www.aviaport.ru/directory/aviation/126.html Заправка топливом. Самолет на земле может быть заправлен двумя способами: открытым, через заливные горловины в крыльевых баках, и закрытым, под давлением - централизованная заправка. Заправка расходных отсеков осуществляется самотеком. Для предотвращения переполнения топливных баков в случае неисправности электрокранов на магистралях заправки устанавливаются гидроклапаны. |
