Alenia Aermacchi Sky-Y
The Italian Alenia Aeronautica Sky-Y is a self-financed MALE Unmanned air vehicle for demonstration and research purpose; on 30 October 2007 it set a new European endurance record in the over 1000 kg category with a spotless eight-hour flight. Since 2016 manufacturer became Leonardo-Finmeccanica as Alenia Aermaccchi merged into the new Finmeccanica (definitively rebranded Leonardo since 2017). Design and development The roll-out of the Sky-Y was carried out by Alenia in June 2007, after 12 months of development, and it first flew at the Swedish test area of Vidsel. As a testbed for key MALE UAV technologies the aircraft include a heavy fuel engine of automotive derivation, a new night and day ATOL system (Autonomous take off and landing), a collision avoidance system and an advanced data link with surveillance sensor data integration. After a first test campaign conducted in order to explore the whole flight envelope and the engine performance the development has focused ...

Aircraft Engine
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Most aircraft engines are either piston engines or gas turbines, although a few have been rocket powered and in recent years many small UAVs have used electric motors. Manufacturing industry In commercial aviation the major Western manufacturers of turbofan engines are Pratt & Whitney (a subsidiary of Raytheon Technologies), General Electric, Rolls-Royce, and CFM International (a joint venture of Safran Aircraft Engines and General Electric). Russian manufacturers include the United Engine Corporation, Aviadvigatel and Klimov. Aeroengine Corporation of China was formed in 2016 with the merger of several smaller companies. The largest manufacturer of turboprop engines for general aviation is Pratt & Whitney. General Electric announced in 2015 entrance into the market.

Fiat FIRE Engine
The FIRE (for "Fully Integrated Robotised Engine") is a series of automobile engines from Fiat Powertrain Technologies, built in FCA's Termoli, Betim and also in Dundee, MI (only in 1.4 Multiair versions) plants. It was designed by Italian design firm Rodolfo Bonetto. It is constructed by robot assembly plants ("Robogate") to reduce costs. The FIRE series replaced the old Fiat 100 series Overhead valve engines in the mid-1980s. Mechanically, they are simple inline-four engines with five main bearings crankshaft and overhead cam heads. Since 1985, it has been constructed in different versions. Displacements range from . In addition to the 8 valve versions, there are "Super-FIRE" 16 valve versions. The "Super-FIRE" which uses 16 valves and is available in (Brazil) and (Brazil & Europe) displacements. The variation introduced in 2003 is available in both 8 and 16 valves. In 2005 Fiat introduced a version of the 16v incorporating port deactivation (PDA) and EGR. This un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light-sport Aircraft
A light-sport aircraft (LSA), or light sport aircraft, is a fairly new category of small, lightweight aircraft that are simple to fly. LSAs tend to be heavier and more sophisticated than ultralight (aka "microlight") aircraft, but LSA restrictions on weight and performance separates the category from established GA aircraft. There is no standard worldwide description of an LSA . LSAs in different countries The civil aviation authorities in different countries have their own particular specifications and regulations which define the LSA category. For example, in Australia the Civil Aviation Safety Authority defines a light-sport aircraft as a heavier-than-air or lighter-than-air craft, other than a helicopter, with a maximum gross takeoff weight of not more than for lighter-than-air craft; for heavier-than-air craft not intended for operation on water; or for aircraft intended for operation on water. It must have a maximum stall speed of in landing configuration; a maximum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brake Specific Fuel Consumption
Brake-specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output. It is the rate of fuel consumption divided by the power produced. In traditional units, it measures fuel consumption in pounds per hour divided by the brake horsepower, lb/(hp⋅h); in SI units, this corresponds to the inverse of the units of specific energy, kg/J = s2/m2. It may also be thought of as power-specific fuel consumption, for this reason. BSFC allows the fuel efficiency of different engines to be directly compared. The term "brake" here as in "brake horsepower" refers to a historical method of measuring torque (see Prony brake). The BSFC calculation (in metric units) To calculate BSFC, use the formula : BSFC = \frac where: :'' r '' is the fuel consumption rate in grams per second (g/s) :'' P '' is the power produced ...

Compression Ratio
The compression ratio is the ratio between the volume of the cylinder and combustion chamber in an internal combustion engine at their maximum and minimum values. A fundamental specification for such engines, it is measured two ways: the static compression ratio, calculated based on the relative volumes of the combustion chamber and the cylinder when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gasses entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to ...

Time Between Overhaul
Time between overhauls (abbreviated as TBO or TBOH) is the manufacturer's recommended number of running hours or calendar time before an aircraft engine or other component requires overhaul. On rotorcraft, many components have recommended or mandatory TBOs, including main rotor blades, tail rotor blades and gearboxes. For engines, the time between overhauls is generally a function of the complexity of the engine and how it is used. Piston-based engines are much more complex than turbine-powered engines, and generally have TBOs on the order of 1,200 to 2,000 hours of running time. They tend toward the lower number if they are new designs, or include boosting options such as a turbocharger. In comparison, jet engines and turboprop A turboprop is a turbine engine that drives an aircraft propeller. A turboprop consists of an intake, reduction gearbox, compressor, combustor, turbine, and a propelling nozzle. Air enters the intake and is compressed by the compressor. Fuel ... ...

MTBF
Mean time between failures (MTBF) is the predicted elapsed time between inherent failures of a mechanical or electronic system during normal system operation. MTBF can be calculated as the arithmetic mean (average) time between failures of a system. The term is used for repairable systems while mean time to failure (MTTF) denotes the expected time to failure for a non-repairable system. The definition of MTBF depends on the definition of what is considered a failure. For complex, repairable systems, failures are considered to be those out of design conditions which place the system out of service and into a state for repair. Failures which occur that can be left or maintained in an unrepaired condition, and do not place the system out of service, are not considered failures under this definition. In addition, units that are taken down for routine scheduled maintenance or inventory control are not considered within the definition of failure. The higher the MTBF, the longer a system ...

JTD Engine
Multijet is Fiat Chrysler Automobiles' term for its current common rail direct injection turbodiesel engine range. Most of the Fiat, Alfa Romeo, Lancia range as well as certain Chrysler, RAM Trucks, Jeep and Maserati vehicles are equipped with Multijet engines. Ownership of some Fiat Multijet designs is shared with General Motors as part of a settlement of the failed merger between the two auto conglomerates. GM Powertrain Torino group in Turin, Italy manages their interest in these engines. Some PSA Peugeot Citroën diesel engines are also rebadged JTD units, and vice versa.(source needed) Fiat's common rail diesel engine is also known as JTD, an initialism of Jet Turbo Diesel.autobild.deJTD - Lexikon - autobild.de accessdate: 19.
