Before entering the fuel heat-sink system, the Environmental Control System (ECS) air leaving the engine compressor at 1,230 °F (666 °C) was so hot that ram air at 760 °F (404 °C) [20] had to be used first. Fuel flowing from the tanks to the engines was used to cool the air conditioning systems, aircraft hydraulic fluid, engine oil ...
The engine can use a variety of fuels, including jet fuel, gasoline, diesel and marine diesel. [2] The engine is a three-shaft machine composed of five sub-modules: [4] Recuperator – a fixed cylindrical regenerative heat exchanger that extracts waste heat from the exhaust gases and uses it to preheat the compressed air
Usually the flow is from the tank to the pump inlet and PRV, pumped to main oil filter or its bypass valve and oil cooler, then through some more filters to jets in the bearings. Using the PRV method of control, means that the pressure of the feed oil must be below a critical value (usually controlled by other valves which can leak out excess ...
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller.
Engines in nacelles on a Boeing 707. A nacelle (/ n ə ˈ s ɛ l / nə-SEL) is a streamlined container for aircraft parts such as engines, fuel or equipment. [1] When attached entirely outside the airframe, it is sometimes called a pod, in which case it is attached with a pylon or strut and the engine is known as a podded engine. [2]
The hydraulic system is also used to extend and retract landing gear, operate flaps and slats, operate the wheel brakes and steering systems. Hydraulic systems consist of engine driven pumps, fluid reservoirs, oil coolers, valves and actuators. Redundancy for safety is often provided by the use of multiple, isolated systems. [3]
An autopilot is designed to perform some of the pilot's tasks. The first aircraft autopilot was developed by Sperry Corporation in 1912. [4] The autopilot connected a gyroscopic heading indicator, and attitude indicator to hydraulically operated elevators and rudder.
The boat was reported to reach a speed of four mph moving upstream. [8] [9] [10] On December 21, 1833, Irish engineer John Howard Kyan received a UK patent for propelling ships by a jet of water ejected from the stern. [11] In April 1932, Italian engineer Secondo Campini demonstrated a pump-jet propelled boat in Venice, Italy. The boat achieved ...
