Elliptical flat tubes have the following applications in the aviation field:
1. aircraft structural components
Wing structure: elliptical flat tube can be used for the internal support structure of the wing. The unique shape helps to reduce the weight and improve the strength and rigidity of the wing to withstand the aerodynamic forces and various loads in flight. Compared with the traditional round or square tube, the section shape of the elliptical flat tube is more suitable for the streamlined design of the wing, which can better match the shape of the wing, reduce air resistance and improve flight efficiency.
Fuselage frame: in the construction of fuselage frame, elliptical flat tube can be used as part of the supporting member. It can optimize the space layout on the premise of ensuring the structural strength of the fuselage, and provide better conditions for the equipment installation, fuel storage and passenger space inside the fuselage. At the same time, the lightweight characteristics of elliptical flat tubes help to reduce the overall weight of the aircraft, thereby improving fuel efficiency and range.
2. aeroengine components
Engine inlet: elliptical flat tube can be used to manufacture part of the structure of engine inlet. The shape and structure of the inlet are very important to the performance of the engine. The shape of the elliptical flat tube can better adapt to the airflow characteristics of the inlet, reduce the airflow turbulence and pressure loss, improve the intake efficiency of the engine, and then improve the overall performance of the engine.
Engine piping system: elliptical flat pipes may also be used in the fuel, lubricating oil and cooling piping systems of aircraft engines. The oval flat tube can be flexibly arranged according to the complex spatial layout inside the engine, and better adapt to the direction and connection requirements of different pipelines. Moreover, its high strength and corrosion resistance can ensure the safe and reliable operation of the pipeline system under the working environment of high temperature and high pressure of the engine.
3. aviation auxiliary system
Hydraulic system pipeline: the aircraft hydraulic system is used to drive various flight control mechanisms, landing gear and other equipment. The elliptical flat pipe can be used as the pipeline of the hydraulic system. The good compressive performance and sealing performance can ensure the stable transmission of hydraulic oil and the normal operation of the hydraulic system. At the same time, the shape of the elliptical flat pipe is helpful to reasonably arrange the pipeline in the limited space and improve the space utilization rate.
Environmental control system: in the aircraft environmental control system, elliptical flat pipes can be used for air conditioning ventilation ducts. It can not only provide comfortable temperature and air quality for the cabin, but also adapt to the complex space structure inside the aircraft to achieve efficient air circulation and distribution. In addition, the material of elliptical flat pipe usually has good thermal insulation performance, which helps to reduce energy loss and improve the energy efficiency of the system.
