Since the creation of the turbine engine, hydromechanical fuel controls have served on many engines, and remain in use to this day. Despite this, their popularity is dwindling due to the rise of electronic based control systems. To ensure proper flow of fuel to the engine, fuel controls systems have two sections: computing and metering. A standard hydromechanical fuel control lacks an electronic interface to assist in computing and metering fuel flow. Once an accurate determination of fuel flow has been made by the computing section, the metering section delivers fuel to the engine via cams and servo valves.
For aircraft to achieve flight, many engines utilize powerful combustion chambers that burn fuel constantly. With this combustion of fuel, intense amounts of heat is created, upwards of 3,500 degrees Fahrenheit. While much of this is vented out of the aircraft as exhaust, there still remains a great amount of heat that must be dissipated, lest it cause the engine to overheat, damage components, reduce the engine’s life, and more.
Plastics are an extremely important part of the aerospace industry, having been commonly used ever since 1970. Plastics excel at reducing weight and improving fuel efficiency, two major considerations in aircraft design, with components for propulsion, navigation, structural elements, and interior all made out of plastic materials. In this blog, we’ll explore five types of plastics commonly used by aircraft manufacturers.
Ambulances aren’t just used on the ground to help trauma patients. “Air ambulance” refers to any form of medical transport that relies on flight for its method of travel, rather than the white-and-red trucks one typically sees on the streets. However, the term “air ambulance” is used for both fixed-wing aircraft and rotary-wing helicopters.
The aerospace and defense industries are complex and hectic industries that require a sense of order. The various aircraft, UAVs, maintenance equipment, and testing components all amass to an enormous group of components and subcomponents that are constantly being manufactured, sourced, and shipped around the globe.
