PBS AI-PBS-350
The AI-PBS-350 is a turbojet engine jointly developed by Czech manufacturer PBS Velká Bíteš and the Ukrainian design bureau Ivchenko-Progress. The engine is marketed for use in missiles and large unmanned aerial systems. As of 2024, it is currently the highest thrust engine developed by PBS, exceeding the thrust of PBS's next highest engine, the PBS TJ150. History On the 19th of June, 2023, Velka Bites and Ivchenko-Progress signed a memorandum of understanding, detailing the framework from which the engine would be developed and produced. Concerns were raised about Ivchenko-Progress' capability to produce the engine, with its headquarters in Zaporizhzhia, a city heavily affected by the Russian invasion of Ukraine. Ivor Kravchenko, the director general for Ivchenko-Progress stated that while the factory had sustained damage, it continues to operate, with strong backing from the Ukrainian government enabling it to maintain its 3000 strong workforce. The engine was display ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jet Engine
A jet engine is a type of reaction engine, discharging a fast-moving jet (fluid), jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include Rocket engine, rocket, Pump-jet, water jet, and hybrid propulsion, the term typically refers to an internal combustion airbreathing jet engine, air-breathing jet engine such as a turbojet, turbofan, ramjet, pulse jet engine, pulse jet, or scramjet. In general, jet engines are internal combustion engines. Air-breathing jet engines typically feature a Axial compressor, rotating air compressor powered by a turbine, with the leftover power providing thrust through the propelling nozzle—this process is known as the Brayton cycle, Brayton thermodynamic cycle. Jet aircraft use such engines for long-distance travel. Early jet aircraft used turbojet engines that were relatively inefficient for subsonic flight. Most modern subsonic jet aircraft use more complex High-bypass turbofan, high-bypas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Control System
In aeronautics, an environmental control system (ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers. Additional functions include the cooling of avionics, smoke detection, and fire suppression. Overview The systems described below are specific to current production Boeing airliners, although the details are essentially identical for passenger jets from Airbus and other companies. An exception was Concorde which had a supplementary air supply system fitted due to the higher altitudes at which it flew, and also the slightly higher cabin pressure it employed. Air supply On jetliners, air is supplied to the ECS by being bled from a compressor stage of each gas turbine engine, upstream of the combustor. The temperature and pressure of this bleed air varies according to which compressor stage is used, and the power setting of the engine. A manifold pressure regulating shut-off valve ...

Auxiliary Power Unit
An auxiliary power unit (APU) is a device on a vehicle that provides energy for functions other than propulsion. They are commonly found on large aircraft and naval ships as well as some large land vehicles. Aircraft APUs generally produce 115 V AC voltage at 400 Hz (rather than 50/60 Hz in mains supply), to run the electrical systems of the aircraft; others can produce 28 V DC voltage. APUs can provide power through single or three-phase systems. A jet fuel starter (JFS) is a similar device to an APU but directly linked to the main engine and started by an onboard compressed air bottle. Transport aircraft History During World War I, the British Coastal class blimps, one of several types of airship operated by the Royal Navy, carried a ABC auxiliary engine. These powered a generator for the craft's radio transmitter and, in an emergency, could power an auxiliary air blower. One of the first military fixed-wing aircraft to use an APU was the British, ...

Turbine Engines
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Modern steam turbines frequently employ both reaction and impulse in the same unit, typically varying the degree of reaction and impulse from the blade root to its periphery. History Hero of Alexandria demonstrated the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farnborough International Airshow
The Farnborough International Airshow is a trade exhibition for the aerospace and defence industries, where civilian and military aircraft are demonstrated to potential customers and investors in Farnborough, Hampshire. Since its first show in 1948, Farnborough has seen the debut of many famous aeroplanes, including the Vickers VC10, Concorde, the Eurofighter, the Airbus A380, and the Lockheed Martin F-35 Lightning II. At the 1958 show, Hawker Hunters of the RAF's Black Arrows executed a 22-aircraft formation loop, setting a new world record. The international trade show runs for five days. Until 2020, the show ran for a full week with the first five days reserved for trade visitors and the general public attending on the weekend. Status The Farnborough International Airshow is the second-largest show of its kind after the Paris Air Show.

Ukrainian Government
The Cabinet of Ministers of Ukraine (), commonly referred to as the Government of Ukraine (), is the highest body of state executive power in Ukraine. As the Cabinet of Ministers of the Ukrainian SSR, it was formed on 18 April 1991, by the Law of Ukrainian SSR No.980-XII. Vitold Fokin was approved as the first Prime Minister of Ukraine. The cabinet is a collegiate body consisting of the cabinet's "presidium" composed of the Prime Minister of Ukraine and their vice prime ministers as well as other ministers who participate and vote on sessions of the cabinet. The prime minister presides over the cabinet. Some vice prime ministers may be appointed as the first vice prime ministers. Unlike the Soviet period of the government when presidium was actually a functioning institution, the current government presidium is nominal and vice prime ministers do not have much advantage over other ministers. All government decisions are being voted for and adopted at the sessions of the cabinet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
