Aircraft rely on various types of engines to generate the power needed for flight. Technology has come a long way since the 1930s when only piston engines were available, and despite being available in many forms, piston engines are limited in their performance abilities. Therefore, the demand for high-performance aircraft gave birth to modern jet engines. This blog will explore the differences between two types of jet engines commonly used in aircraft today: the turbojet and the turboprop. Although both are jet engines, aircraft that rely on turbojets are considered jet aircraft while aircraft that rely on turboprops are considered propeller aircraft. Reasonably, the main distinguishing factor between the two engines is that a turboprop makes use of a propeller before the inlet leading into the engine, whereas turbojets lack this feature. Given the difference in their design, both jet engines offer their own advantages and drawbacks, those of which we will further explore below.

An actuator is a device that makes something move, allowing for hands-off operations to be possible. Actuators are classified based on where they source their energy from, and actuators used in machinery are typically electric, hydraulic, or pneumatic. An electric actuator runs on electricity and can be found in an electric engine. A hydraulic actuator runs on incompressible oil, or hydraulic fluid, and can be found in the steering gear of a ship. Lastly, a pneumatic actuator compresses air and creates kinetic energy through movement, and such parts can be found across many applications. This blog will explore the diverse functions of pneumatic actuators in particular and the way actuators operate.

While sitting comfortably in the cabin of a commercial aircraft, it is easy to forget the immense altitude at which the plane is flying. Reaching a cruising altitude of 30,000ft with every flight, airplanes are explicitly designed to protect occupants from the low oxygen concentrations found in this extreme environment. In order to accomplish this, all aircraft flying above 10,000ft have pressurized cabins, ensuring a safe and comfortable flight for both passengers and crew members. In this blog, we will discuss everything you need to know about cabin pressurization, including its purpose, design, and implementation.

Lock-nuts have a locking ability to resist loosening caused by pressure, force, and vibration. A free-spinning nut works to prevent vertical movement with the help of force that only serves for holding the fasteners. Unlike ordinary nuts, lock-nuts are distorted elastic and metal materials that are used to tighten components to protect them against vibration and torque. The uses of lock-nuts may vary according to the elements that need to get fastened. In this blog, we will take a brief look at the most common types of lock-nuts.

Valve train components are often present within the mechanical systems of a diesel engine or other similar apparatus, serving to manage the operations of intake and exhaust valves. By controlling the intake valves, the fuel-and-air mixture that is being combusted can be governed, while the exhaust valves serve to expel spent gasses from the combustion chamber. Despite being somewhat simplistic in their role, valve train components are essential for the proper functionality of an automobile, aircraft, or other vehicle type harnessing a combustion engine.

Linear actuators are quite common to various applications, coming in the form of an electro-mechanical component that can create motion in a straight line. Often found in industrial machinery, valves, computer peripherals, and more, linear actuators create the necessary linear motion for different processes through the use of mechanics, hydraulics, or pneumatics. In some instances, feedback controls may be necessary, and such characteristics may be managed with the use of sensors and limit switch features.

A control valve is a specialized valve type that is capable of managing the flow of fluids through their ability to change the size of their passage. With all types of control valves, a control system serves to relay commands for adjusting the size of the opening. The force that enacts these changes is made possible through control valve actuators which act directly on the valve or through the use of a control valve positioner. In this blog, we will discuss the primary types of control valve actuators that are used for flow changes, allowing you to find the best fit for your particular needs.

Electrical components can often be sensitive to overload conditions, quickly breaking down or malfunctioning when voltages exceed intended limits. Faults such as short circuits can also be hazardous to individuals as well, posing the risk of shock or combustion if in the presence of combustible materials. As a result, it is paramount that all electrical system components are provided ample protection from overload conditions, that of which is achievable with a device known as a circuit breaker.

The aircraft piston engine, or reciprocating engine, is a type that has served powered flight since its inception, acting as the most common power plants for general aviation aircraft even to this day. While there are numerous piston engine types that slightly differ in their construction, all operate according to the four-stroke cycle of intake, compression, power, and exhaust. To conduct such operations, piston engines rely on pistons and cylinders that are assembled in various ways to achieve different flight characteristics. In this blog, we will provide a brief overview of the most common piston engine types so that you may be more familiar with their differences and capabilities.

When assembling components with the use of bolt fasteners, it is important to have an accommodating nut component for the means of securing the bolt. Nuts are fasteners that feature a threaded hole, and they are paired with bolts to keep assemblies together through friction, bolt stretching, and compression. Depending on the assembly and its needs, there are a variety of nut types that may be used alongside a bolt. When there is a desire for easy component installation without the need for many tools, the wing nut fastener proves to be a useful choice.

Navigation refers to the process of planning, recording, and controlling the movement of a craft from one location to another. More specifically, air navigation involves piloting an aircraft from one place to another without getting lost, breaking any aviation laws, or endangering the safety of those on the aircraft or on the ground. In older aircraft, the pilot was accompanied by a flight navigator, who was responsible for trip navigation. With the introduction of sophisticated electronic GPS navigation systems, this role was rendered obsolete. Since this, advancements in air navigation technologies have continued. In this blog, we will discuss four new and exciting air navigation systems.
