Example Embodiment

[0023] The present invention will be further described below in conjunction with drawings and implementation.

[0024] like figure 1 Shown is a schematic diagram of an aircraft with 4 engines running on 2 fuels. The aircraft system of this embodiment includes a fuselage 2 and a wing 1 connected to the fuselage 2. The aircraft system generates thrust through an engine 3 of a power system. The power system of this embodiment includes 4 engines 3 and is positioned on the wing 1. In other embodiments, three engines 3 can also be used, two of which are located on the wing 1 , one is located on the tail 6 , or all three engines 3 are located on the tail 6 .

[0025] There are two fuel storage systems on the aircraft to provide fuel for the engine 3, the fuel tank 4 is located in the wing 1 to store conventional aviation kerosene, and the LNG storage tank is located on the fuselage 2 close to the connection between the wing 1 and the fuselage 2. In other embodiments, the LNG storag...

Abstract

The invention discloses a fuel supply system applied to an aircraft engine taking an LNG as a fuel. The fuel supply system comprises an LNG storage tank, an LNG low-pressure pump, a gas low-pressure pump, a gasification device, a gas high-pressure pump, a flow controller, a fuel oil branch pipe, a gas fuel nozzle and a combustor. The fuel supply system has the beneficial effects that the system complexity is lowered, the reliability of a power system is improved, the pollutant discharge due to a used liquid fuel is lowered, and the whole performance of the aircraft engine is improved; an alternate working mode and a simultaneous working mode, which are different, of the engine are adopted according to different thrusts output by the power system, so that the transportation cost is lowered on the premise of ensuring that the needed thrust is provided.

Description

technical field [0001] The invention relates to the technical field of aircraft engines and fuel supply, in particular to a fuel supply system applied to an aircraft engine fueled by LNG. Background technique [0002] With the development of human society and economy, the global aviation industry is developing rapidly. At present, there are about 3,750 airports in the world, more than 2,000 airlines, and nearly 23,000 aircraft fly in the air every day. In recent years, my country's air transport industry has generally shown an upward trend and is in good development. As of the end of 2013, the number of transport aircraft in the industry was 2,145, and there were 2,876 scheduled flight routes. The route mileage calculated by non-repeating distance was 4.1 million kilometers. In 2013, the accumulative revenue was 588.96 billion yuan, the total turnover of transportation was 67.172 billion ton-kilometers, and the passenger transportation volume was 3.54 billion person-times. ...
