There are several operating cycles used by reciprocating engines, including a four-stroke cycle, two-stroke cycle, rotary cycle, and diesel cycle. However, a majority of certified reciprocating engines operate on the four-stroke cycle; thus, it is the most widely recognized operating cycle. Also called the Otto cycle after its originator, a German physicist, the four-stroke cycle engine has many advantages over its counterparts. In this type of engine, four strokes are required to complete a series of subcycles in each cylinder.
  1. Intake Stroke

During the intake stroke, the piston is pulled downward in the cylinder by the rotation of the crankshaft. This decreases the pressure in the cylinder and causes air under atmospheric pressure to flow via the carburetor which meters the correct amount of fuel. Then, the fuel-air mixture makes its way through the intake pipes and intake valves into the cylinders.

Aircraft are designed with a wide range of parts and components that ensure they remain operable for long periods of time. Apart from aviation-grade fasteners, flight control surfaces, and navigation instruments, aircraft are equipped with pressure hoses. From light to twin-aisle, wide-body aircraft, a majority of aircraft feature them in their construction.

Landing gear is essential for an airplane, serving the function of mitigating landing and takeoff incidents on the runway. All landing gear comprises wheels for this purpose in addition to a collection of various other components depending on the operations the gear performs. As such, landing gear can be categorized by its configuration into different types, one of which is tailwheel-type landing gear. For your better knowledge, this blog will cover this type of landing gear and its benefits.

Aircraft pilots and engineers have long known stalls and spins as several of the most dangerous issues that can occur mid-flight. To address these risks, many modern aircraft are affixed with leading edge cuffs, a wing design element which improves safety and control while in flight. Commonly called Drooped Leading Edges (DLEs), these components are essentially adjustable surfaces that can be attached to the leading edge of an airplane wing. By “drooping” downwards, they add an additional control surface which affects the flow of air across the surface and underside of a plane’s wing. For their ability to lend enhanced control and safety to pilots, leading edge cuffs are an essential mechanism in the aviation industry. For more information about these revolutionary parts, read on as we discuss five key facts you should know about leading edge cuffs.

Of the millions of components that make up a commercial aircraft, nearly 50% are fasteners. These critical devices help bind structural areas of the plane and secure other elements in their required place. Due to the varying architecture of different aircraft regions, it is important to note that there is a diverse range of fastening devices found in aviation. Regardless of the design, the fasteners should be durable and resistant to the various stressors encountered by the plane. In this blog, we will discuss the spring pin, which is a mechanical fastener used to join pieces together securely.

Aviation encompasses a myriad of concepts, one of which includes the flight envelope. Whether propeller or jet engine-driven, all aircraft are equipped with a flight envelope. As such, pilots must familiarize themselves with their airplane’s flight envelope for safety purposes. To better understand the underlying mechanisms of these complex devices, this blog will provide a brief overview of their basic features and importance.

Radio communication is intrinsic to air traffic control (ATC) within the aviation sector. When operating an aircraft several miles above sea level, having an effective communication channel between pilots onboard other airplanes and aviation personnel on the ground is paramount to avoid collisions. However, before the advent of radio communication, pilots and controllers used to depend on flags and other outdated signals to transmit messages until rudimentary radio communication systems emerged. Now, modern aircraft rely on far more advanced communication systems such as satellite and radio transmitters, enabling more effective flight operations and exchange of information.

In aviation, pilots utilize avionic radios, also known as air band radios, for both navigation and communication. Air band radios rely on VHF frequencies of 108 MHz to 137 MHz because the FCC designated separate, specific channels to both land based and air based radios. Trans-oceanic aircraft may use HF frequencies as well, but for aircraft traveling over land and open spaces, avionic radios depend exclusively on VHF frequencies. The transmissions occur from either ground to air or air to air, so they cover large distances and have a much greater range than on the ground radio stations.

When looking for cutting tools to utilize for aerospace operations, some of the most popular are aviation snips. Though they may appear like a typical pair of shears, aviation snips have a handle and a cutting blade that allows them to achieve many different types of cuts. They are defined as handheld cutters that are designed for use with sheet metal.
