There are many different types of aircraft valves that can be used for the aircraft engine. While they each have different physical characteristics and serve different purposes, the aircraft valves tend to operate in a similar fashion. For example, the valves in the cylinders of an aircraft engine must endure severe conditions, including high temperatures, corrosion, and operating stresses. For this reason, metal alloy is often used in most valves so that they can resist and withstand being subject to extreme factors. However, some valves, such as intake valves, must function at temperatures lower than exhaust valves, and can thus be made of chromium-nickel steel. On the other hand, exhaust valves can be built of nichrome, silchrome, or cobalt-chromium steel because these materials are much more heat resistant. For more information on the different aircraft valve types, see below for more information.

The future of commercial in-flight passenger experience is one of both technology advancements and engineering achievement. With the invention of virtual reality in 1957 to now the most advanced VR headset, the StarVR One, Airbus -- a leading name in the commercial passenger service -- recently patented a Virtual Reality Helmet for its passengers. The helmet will offer sensorial isolation and endless entertainment possibilities that would make the flight time on a normal US coast to coast flight, literally, fly by.

An aileron is the hinged surface in the outermost trailing edge of an airplane wing, designed to control the lateral balance of the plane as it cruises through flight, or during its roll. The ailerons and how they function in relation to the aircraft is something that every pilot and/or aircraft enthusiast should know. Read on below for a basic outline of how the ailerons function.

As a natural side-effect of combustion, piston engines generate large amounts of heat that needs to be managed. An engine’s internal components are cooled by the oil system, but the external components, such as the cylinder heads, need to be cooled as well. While some engines feature water cooling systems and radiators, most general aviation aircraft use air cooling introduced by the cowling at the front of the front of the engine compartment, and a system of baffles within the compartment to distribute air.

Like all complex machinery, aircraft design is highly iterative. Blueprints will be drawn and redrawn dozens of times over the course of an aircraft’s development, and this holds true for an aircraft’s pylons as well. The pylon, the structure that attaches the aircraft’s engines to its wings, is a critically important part of the fuselage, and so goes through multiple iterations.

We don’t really think about it, but it’s amazing that we fly year-round. We fly in the heat of summer and in the cold of winter. And we do so safely and without worry. Most of the time at least. But if stop to think about it a bit, we’d realize that flying in the winter, when it’s so cold that water freezes to form snow and ice in seconds, is dangerous because just a bit of ice freezing on the wrong part of an engine could be disastrous.

• Wooden propeller blades:

All you need to be able to clean wooden blades is some mild detergent and warm water. Wooden blades also use brushes or cloth to clean the dirt and grime off the propellers.  

A new chapter for the Bombardier team has finished as they are able to complete their Global 7000 program deeming their Global 7000 FTV aircrafts as airworthy. The entire program was wrapped up as their anchor aircraft, known as the “The Masterpiece” completes its prerequisites for certification. Alongside the continuous tests it managed to also abide by “full airframe fatigue test milestone” regulations that is required for it enter in to service.
