There are distinct advantages to flying at high altitudes. These include decreased drag, faster true airspeed, and higher tailwinds (when applicable). However, these advantages bring with them a major disadvantage for any aspirated engine: a lack of air. Air pressure decreases at higher altitudes, and does so quickly. For example, at 18,000 feet elevation, 50% of the entire atmosphere is beneath your aircraft. This means there is much less oxygen for your engine to burn, resulting in a deficiency of horsepower. So, how do aspirated engines, engines that require oxygen to function, solve this problem? There are multiple ways, one of which is called turbo-normalization.
Electrical wires and cabling are utilized in nearly all sectors including commercial, private, military and other areas. While they are often used interchangeably, there is a distinct difference between the two. Though they both act as the electric delivery system at home, wires indicate that they are simply one electrical conductor and cables indicate that they are a group of wires encased in a sheathing.
During standard engine operation, heat can quickly increase due to moving parts, combustion of fuel, and other mechanical processes. This heat can build up to dangerous levels if unchecked, damaging components and systems alike. One major way in which engines are typically cooled on an aircraft is through the use of colder air within the atmosphere that is directed throughout components and systems. Aircraft engine baffle seal material is an important element to engine cooling for piston powered aircraft, allowing for airflow regulation through an engine compartment. In this blog, we will discuss what engine baffles are, as well as how they cool aircraft engines.
A National Stock Number (NSN) is an officially recognized moniker given to any item of supply that is in wide use throughout the federal supply system. It is sometimes referred to as a NATO Number and is comprised of a series of numbers used to identify a single unique item. When the NSN is assigned, data such as item name, manufacturer part number, unit price, and physical characteristics are all taken into consideration to provide an accurate set of digits to describe the part. National Stock Numbers are a critical aspect of the logistics supply chain of militaries throughout the world for their management, movement, storage, and disposal of materials.
Aircraft window seats are often the coveted placement of any plane. You can rest your head, be away from the aisle, and the outside view can be amazing depending on where you are flying above. Beyond the beauty and comfort they bring, aircraft windows also provide protection from the outside temperature and pressure which can be harmful. Because of this, aircraft windows are built to be very strong and follow many rules and regulations for design as set by authorities such as the FAA.
When you’re headed to work on a cold winter’s morning and start the car for your daily commute, you may have noticed a blue light on your dashboard. This light denotes that your coolant temperature is low, meaning your car has not yet heated up. While this little blue light is not necessarily cause for concern, it does indicate that your car is not operating at its full potential. Just as your car needs time to heat up, so too does an aircraft. The difference is that performance issues on the ground are much more manageable than in the air, so preheating the aircraft engine is not something to take lightly.
In late 2018, the British National Police Air Service (NPAS) leapt into the future of law enforcement by investing 1.5 million GBP to equip their fleet of helicopters with night vision. The NPAS fleet has seven Airbus H135 helicopters among its ranks, all of which have been equipped with night vision, or NVIS, technology. Giving their fleet the capability of ground level NVIS will vastly improve their night surveillance capabilities in any environment.
A type of fastener, washers are thin disk-shaped plates with a hole in the center, used in conjunction with a threaded fastener such as a screw or bolt. Washers distribute load, create separation, prevent corrosion and wear, lock fasteners into place, and reduce vibrations. Washers are typically made from metal or plastic, although rubber and fiber are used as well in limited applications. Washers vary in size, but typically have an outer diameter roughly twice that of the inner diameter.
With any form of technology, the yearning for improvement and more efficiency is ever present, and aircraft engines are no different. Since the creation of the engine, industrialists have been searching for any way that they can increase their functionality and abilities. With most piston engines, only one-third of energy is harnessed for work while the majority is wasted as exhaust. Since their inception, improvements to this potential energy has been found in the form of turbochargers and superchargers, which enables engines to gain a significant powerboost.
You may be familiar with the European Union Aviation Safety Agency (EASA) or Federal Aviation Administration (FAA), but there are not many people who are familiar with the Air Safety Support International or ASSI. ASSI is a non profit subsidiary organization of the United Kingdom Civil Aviation Authority. Their goal is to establish a system of civil aviation safety regulations in the United Kingdom. In other words, they’re the small faction of the CAA that manages aviation regulation for the UK Overseas Territories.
