Bleed air, the compressed air that originates from the compressor section of a turbine or auxiliary power unit, is a critical component of jet engine functionality. Gas turbine engineers use bleed air in many different ways throughout an aircraft to improve its efficiency. In fact, the successful distribution of bleed air is vital to the operation of an aircraft. To do this, air bleed valves have a critical role. Because bleed air valves have to be reliable even at extreme temperatures and in dry conditions, they are primarily made from carbon graphite. This material is a popular choice due to its ability to lubricate rubbing components.
An axle is a central shaft for a rotating wheel or gear. On wheeled vehicles, the axle may be fixed to the wheels, rotating with them, or fixed to the vehicle with the wheels rotating around the axle. Generally speaking, there are three types of axles: rear, front, and stub axles. This blog will explain each of the three types and what makes them unique.
Fuel oil has many various uses for both business and the home. Such examples of ways to use fuel are lighting up the engine for a vehicle, heating up a home, producing steam to generate electrical energy, etc. Fuel, which can also go by the names of home heating oil, kerosene, coal oil, and diesel fuel, is produced from liquids that are burnable and that are derived from crude oil. It can be used to power engines, heaters, stoves, lanterns and more.
When people think of diesel engines, they often compare them with the standard gasoline engine and picture a sootier and noisier engine. While diesel has the advantage and capabilities to haul large shipments over long distances, this tendency to produce more smoke and noise turns the majority of consumers off. Not only that but they have become strongly associated with trucks and large vehicles. Overall diesel engines are more efficient and thanks to advancements in technology, are steadily more cleaner and less noisier. In this article, we will look closely at diesel engine parts and their various functions.
There are strong advantages and disadvantages for fixed wing aircraft and rotary wing aircraft and depending on what you need, each have their respectable purpose and utility. A fixed wing aircraft would be your basic airplane, utilizing wings, the airspeed generated from forward motion, and wing design and shape to create lift and thus flight. A rotary wing aircraft, such as a helicopter, uses rotary wings or rotor blades that revolve around the mast to create lift and flight. The projected distance from point A to point B, capacity needs of cargo and supply, weather conditions like strong winds, the environment in which take off takes place, how much time is allowed to reach said destination, and flight demands once in the air, all are determining factors in deciding which aircraft is better suited for a pilot’s mission at hand.
Before the Industrial Revolution, most manufacturing of items was done by a single craftsman. From start to finish, one person would work to create an item before moving onto the next, often leading to long wait times for production and the need for a great amount of skills for a craftsman. With the creation of the assembly line, and later machined assembly, the process of production could be broken up into various steps and work stations that allowed for multiple employees and machines to service parts of an item at a time. This allowed for the reduction of production time, as well as the division of manufacturing labor. In this article, we will give a short overview of assembly machinery and their part in modern manufacturing.
Aircraft rigging is the process of adjusting movable flight controls on major aircraft surfaces like wings and stabilizers. Ailerons, elevators, and rudders are all examples of aircraft rigging gear. Besides the flight controls, rigging is also done to other areas of the aircraft to incorporate engine controls, flight deck controls, and components of retractable landing gear. Attachment of hardware using cotter pins, locknuts, or safety wire is also included in the rigging process.
The standard propulsion system seen on commercial aircraft is a twin turbofan gas turbine engine assembly. Airbus and Boeing utilize this dual engine system on most of their aircraft. The fuel-efficient assembly is widely used in high-speed transport and has helped propel the aerospace industry to what it is today (pun intended).
Diesel engines are internal combustion engines. The main difference compared to other internal combustion engines is how the fuel is ignited. Hot air from the compressor is transferred to the combustion chamber, but instead of requiring an ignitor, the air is hot enough that when the fuel is injected, it spontaneously combusts. Spontaneous combustion is the result of two things, the self-ignition temperature of diesel and the compression ratio of diesel engines.
