AW249
The Leonardo Helicopters AW249 Fenice (English: ''Phoenix'') is an attack helicopter project under development by the Italian firm Leonardo. Development of the AW249 formally started upon receipt of a €487 million contract from the Italian Army as a replacement for the Agusta A129 Mangusta. It is to be larger, more survivable, and have greater autonomy than the Mangusta, incorporating stealth technologies and mission systems to control unmanned aerial vehicles (UAV)s. Numerous mature technologies will also be incorporated, such as the OTO Melara TM197B 20 mm chin-mounted cannon, Rafael Advanced Defense Systems Toplite targeting system and Spike missile, it is intended for the AW249 to have lower operating costs than the preceding Mangusta. Leonardo is actively seeking partners to collaborate on the AW249; a letter of intent on this matter was signed with the Polish Armaments Group during July 2018. The maiden flight of the AW249 was originally scheduled to take place d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agusta A129 Mangusta
The Agusta A129 Mangusta () is an attack helicopter originally designed and produced by Italian company Agusta. It is the first attack helicopter to be designed and produced wholly in Europe. It has continued to be developed by AgustaWestland, the successor company to Agusta. It has been exclusively operated by the Italian Army, which introduced the type to service during 1990. The A129 has undergone several combat deployments, seeing use in Somalia, Afghanistan, and Iraq. It has proven well suited to operating in hot climates, as well as quite flexible in the field. The original 60 rotorcraft have been upgraded multiple times since entering service with the Italian Army; improvements have included compatibility with additional munitions, new targeting systems, improved avionics, better data-handling, and a more powerful transmission. Various improvements and export models have been proposed, including dedicated naval and reconnaissance variants. The TAI/AgustaWestland T129 ATAK ...

General Electric T700
The General Electric T700 and CT7 are a family of turboshaft and turboprop engines in the class. Design and development In 1967, General Electric began work on a new turboshaft engine demonstrator designated the "GE12" in response to US Army interest in a next-generation utility helicopter. The GE12 was designed and conceived by GE's Art Adamson and Art Adinolfi. In 1967, both GE and Pratt & Whitney were awarded contracts to work parallel with each other to design, fabricate, and test the technology. The Army effort led, in the 1970s, to development of the Sikorsky S-70 Black Hawk, powered by twin GE "T700" turboshafts, the production descendant of the GE12. The T700 was initially bench-tested in 1973, passed military qualification in 1976, and went into production in 1978. The initial "T700-GE-700" is an ungeared free-turbine turboshaft, with a five-stage axial / one-stage centrifugal mixed-flow compressor, featuring one-piece "blisk" axial stages, with the inlet guide vanes a ...

Aviation Week & Space Technology
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network, a division of Informa. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960.

Maximum Take-off Weight
The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, i ..., also known as the maximum structural takeoff weight or maximum structural takeoff mass, is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits. The analogous term for rockets is gross lift-off mass, or GLOW. MTOW is usually specified in units of kilograms or pounds. MTOW is the heaviest weight at which the aircraft has been shown to meet all the airworthiness requirements applicable to it. It refers to the maximum permissible aircraft weight at the start of the takeoff run. MTOW of an aircraft is fixed and does not vary with altitude, air temperature, or t ...

Infrared Signature
Infrared signature, as used by defense scientists and the military, is the appearance of objects to infrared sensors. An infrared signature depends on many factors, including the shape and size of the object, temperature, and emissivity, reflection of external sources ( earthshine, sunshine, skyshine) from the object's surface, the background against which it is viewed and the waveband of the detecting sensor. As such there is no all-encompassing definition of infrared signature nor any trivial means of measuring it. For example, the infrared signature of a truck viewed against a field will vary significantly with changing weather, time of day and engine loading. Two fairly successful examples of defining the infrared signature of an object are the apparent temperature difference at the sensor and the contrast radiant intensity (CRI) definitions. Apparent temperature difference The apparent temperature difference method of defining infrared signature gives the physical temperat ...

Radar Cross-section
Radar cross-section (RCS), denoted σ, also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. An object reflects a limited amount of radar energy back to the source. The factors that influence this include: *the material with which the target is made; *the size of the target relative to the wavelength of the illuminating radar signal; *the absolute size of the target; *the incident angle (angle at which the radar beam hits a particular portion of the target, which depends upon the shape of the target and its orientation to the radar source); *the reflected angle (angle at which the reflected beam leaves the part of the target hit; it depends upon incident angle); *the polarization of the radiation transmitted and received with respect to the orientation of the target. While important in detecting targets, strength of emitter and distance are not factors that affect the calculation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
