Pusher Configuration
In an aircraft with a pusher configuration (as opposed to a tractor configuration), the propeller(s) are mounted behind their respective engine(s). Since a pusher propeller is mounted behind the engine, the drive shaft is in compression in normal operation. Pusher configuration describes this specific (propeller or ducted fan) thrust device attached to a craft, either aerostat (airship) or aerodyne (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboat and propeller-driven snowmobiles. "Pusher configuration" also describes the layout of a fixed-wing aircraft in which the thrust device has a pusher configuration. This kind of aircraft is commonly called a pusher. Pushers have been designed and built in many different layouts, some of them quite radical. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplanes) were ...

Hybrid Electric Aircraft
A hybrid electric aircraft is an aircraft with a hybrid electric powertrain. As the energy density of lithium-ion batteries is much lower than aviation fuel, a hybrid electric powertrain may effectively increase flight range compared to pure electric aircraft. By May 2018, there were over 30 hybrid electric aircraft projects, and short-haul hybrid-electric airliners were envisioned from 2032. History The Boeing Truss-Braced Wing subsonic concept was planned with hybrid electric propulsion. The Diamond DA36 E-Star first flew on 8 June 2011, the first flight of a series hybrid powertrain, reducing fuel consumption and emissions by up to 25%, a technology scalable to a 100-seater airliner. A small and lighter Austro Engine 40 hp (30 kW) Wankel engine generates the electricity, supplemented by EADS batteries for silent take off, feeding a Siemens 70 kW (94 hp) electric motor turning the propeller. The AgustaWestland Project Zero was intended to be hybrid-electri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pipistrel E-811
Pipistrel d.o.o Ajdovščina is a Slovenian light aircraft manufacturer established in 1989Or 1989... --> by Ivo Boscarol and based in Ajdovščina. Its facilities are located in Ajdovščina, Slovenia, and near the town of Gorizia, Italy. By March 2019, Pipistrel had produced more than 2000 aircraft. In April 2022, the company was purchased by Textron. History Due to legal restrictions imposed by the Yugoslavian government during the 1980s, the first aircraft was flown secretly in the evening, between dusk and dark. The flying times and triangular shape of the hang-glider style wings earned the aircraft the nickname "bats" which was adopted by the company naming themselves after the Italian word for bat, pipistrello. Initially Pipistrel produced only powered hang gliders, designed by Ivo Boscarol, who produced experimental ultralight trikes with a group of his friends as a private enterprise starting in the mid-1980s. The first serially-built ultralight trike, the Basic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gasoline
Gasoline (; ) or petrol (; ) (see ) is a transparent, petroleum-derived flammable liquid that is used primarily as a fuel in most spark-ignited internal combustion engines (also known as petrol engines). It consists mostly of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, U.S. refineries produce, from a barrel of crude oil, about 19 to 20 gallons of gasoline; 11 to 13 gallons of distillate fuel (most of which is sold as diesel fuel); and 3 to 4 gallons of jet fuel. The product ratio depends on the processing in an oil refinery and the crude oil assay. A barrel of oil is defined as holding 42 US gallons, which is about 159 liters or 35 imperial gallons. The characteristic of a particular gasoline blend to resist igniting too early (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating, which is produced in several grades. Tetraethyl lead and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AVGAS
Avgas (aviation gasoline, also known as aviation spirit in the UK) is an aviation fuel used in aircraft with spark-ignited internal combustion engines. ''Avgas'' is distinguished from conventional gasoline (petrol) used in motor vehicles, which is termed ''mogas'' (motor gasoline) in an aviation context. Unlike motor gasoline, which has been formulated since the 1970s to allow the use of platinum-content catalytic converters for pollution reduction, the most commonly used grades of avgas still contain tetraethyllead (TEL), a toxic substance used to prevent engine knocking (premature detonation). There are ongoing experiments aimed at eventually reducing or eliminating the use of TEL in aviation gasoline. Kerosene-based jet fuel is formulated to suit the requirements of turbine engines which have no octane requirement and operate over a much wider flight envelope than piston engines. Kerosene is also used by most diesel piston engines developed for aviation use, such as tho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Euro-pallet
The EUR-pallet, also known as Euro-pallet or EPAL-pallet, is the standard European pallet as specified by the UIC pallet working group and the UIC 435-2 leaflet. Pallets conforming to the standardization are eligible for the European Pallet Pool (EPP), the system which allows for an exchange as "pallet for pallet". The EUR/EPAL-pallet is ; it is a four-way pallet made of wood that is nailed with 78 special nails in a prescribed pattern. The weight of a EUR/EPAL-pallet (EPAL 1) is approx. 25 kg. Around 450-500 million EUR-pallets are in circulation. The safe working load of a EUR/EPAL-pallet is 1,500 kg. The maximum additional load can be up to 4,000 kg when stacking. The EUR/EPAL-pallet may weigh up to . (1.5 metric tonnes) when equally loaded, otherwise the limit is . History The Euro-pallet dates back to the wooden pallets used in railway transport. In 1961 the European railways commissioned the standardization of a common pallet type under the auspices of the UIC. The ...
