Galling is a form of wear resulting from metal surfaces gliding against one another. It most frequently occurs in fasteners that are subjected to a lot of motion, like those that are fastened and unfastened regularly, or those that must withstand a great deal of vibration. Galling is particularly prevalent in fasteners such bolts, bushings, or other fasteners used to hold an aircraft together. As it can cause potentially disastrous results, manufacturers in the aircraft industry must combat galling. This blog will explain the many steps a manufacturer can take to prevent it from occurring.

Diesel aircraft engines are those that utilize diesel fuel for operation, and they have served airships and some aircraft since the 20th century. Diesel aero engines feature various advantages such as excellent fuel consumption, low flammability, and high density fuel levels. Nevertheless, they are not as widely implemented in modern aircraft as compared to the turboprop engine or gasoline engines. In this blog, we will discuss the aircraft diesel engine, their various components, and their projected future for aviation moving forward.

A magnet is an object that is able to produce a magnetic field, and they have been a benefit to the engineering sector and across various industries for a great amount of time. Within the realm of aerospace, magnets prove useful in a variety of applications due to their capability to function for a long amount of time and within more harsh environments. Magnets benefit systems such as aircraft loudspeakers, the fuel pump, flow regulators, actuation system, air compressor, flight control system, and much more. Due to the many uses that magnets provide for aircraft, it is important to understand more about how they work, as well as how they aid operations.

Gyroscopes are an important part of any internal guidance or navigation system of aircraft. Despite being invented over a century ago, they remain in use to this day. A gyroscope is a device that uses the Earth’s gravity to measure or maintain orientation and angular velocity. The configuration features a spinning wheel or disc in which the axis of rotation is free to take on any orientation. While in rotation, the orientation of this axis is not affected by titling or rotation of the mounting. Gyroscopes have applications throughout the aerospace, aviation, marine, and defense industries. They guide ballistic missiles and satellites, aid in the building of tunnels, and work in ship gun fire control systems.

Out of every standard gear used for mechanical systems, the spur gear remains the most simple and widely used. Typically, they consist of a circular gear body with straight teeth across the entirety of the circumference. They also feature parallel and coplanar shafts. Alone, spur gears can provide for rotational motion, though if paired with a gear rack, can also create linear motion. Spur gears can be produced from a variety of materials, ranging from metals to polycarbonate plastics. Due to their simplicity, spur gears are easy to design and produce, thus making them very cheap and economical for a wide range of applications.
