Airspeed provides critical information to the aircrew about aircraft safety conditions during flight. Aircraft are expected to maintain level flight without exceeding certain speeds or flying under the standard limit. If the aircraft is going too slow, the aircraft may stall. Alternatively, if the aircraft is going too fast, the pilot risks structural failure. As such, an aircraft airspeed indicator is an integral part of the aviation industry. In this blog, we will cover the inner-workings of an aircraft airspeed indicator and its importance.

Diodes are common to numerous electrical devices, and the PIN diode in particular is a variation of the PN-junction that may benefit various applications. As an advancement over conventional PN-junction diodes, the PIN diode comes in the form of a 3-layer device where an intrinsic layer is situated between P and N regions. The intrinsic region of the diode allows for the component to feature high properties of resistance, coupled with a large electric field. As a result, the electronic and hole pair generation of the region is increased so that a weak input signal may be operated.

Bearings are common machine elements that are implemented within countless assemblies for minimizing friction between moving surfaces and constraining motion. Depending upon the assembly and its requirements, there are multiple types of bearings that may be used, each with their own unique characteristics and designs. In particular, the spherical plain bearing is a type of radial spherical plain bearing capable of managing high radial loads with consistent performance under harsh conditions.

Within the realm of aviation, the fuselage is the structure which will contain the crew, passengers, and cargo. Additionally, fuselages also act as a connection point for the cockpit, wings, tail, and other various structures to be attached. Over the years with significant aircraft engineering development, a number of fuselage designs have come about. As each type differs in materials used and general design, it can be beneficial to have a basic understanding of each.

When attempting to transfer steam, water, coolant, hydraulic air, or other media types through piping and rotating systems, devices known as rotary joints or rotary unions are used. A rotary union is a type of rotary sealing device, capable of bridging the gap between a fixed pipe and a rotating equipment piece. While rotary unions are often relied on for the transfer of various media, they also serve to seal the passage between the stationary piping or tubing and the rotating element. In this blog, we will discuss the design and functionalities of rotary joints and unions, allowing you to better understand how they serve fluid applications.

A switch is an electrical device used to manually or automatically create or break an electrical circuit. Switches can be mechanical or electronic. Mechanical switches are operated physically, while electronic switches are activated by semiconductor action. Generally speaking, switches are classified into four types: Single Pole Single Throw (SPST), Single Pole Double Throw (SPDT), Double Pole Single Throw (DPST), and Double Pole Double Throw (DPDT).

An aircraft tach generator is an electromechanical device that is capable of determining the speed of motors, engines, and other various rotational devices. When implemented on an aircraft, such devices are regularly used to measure the revolutions of the engine, indicating engine RPM and/or rotor RPM. As tach generator devices are common to aircraft applications, understanding how they are designed and how they function can be useful for any pilot or aircraft engineer.

For an aircraft to achieve and sustain flight as we are familiar with today, they require some method of producing propulsion and thrust. For aircraft that need high amounts of combustion and force to drive their systems, gas turbine engines prove to be the most widely used types. With the turboprop engine in particular, the combustion of fuel-and-air mixtures is harnessed to drive propellers, unlike other gas turbine types. From business jets to military attack aircraft, turboprop engines prove very popular for a variety of aerospace applications. To best understand their usefulness for certain aircraft, it can be very beneficial to first be aware of their design and functionality.
