Novi Avion
The Novi Avion (Serbian Cyrillic:Нови Aвион en, New Aeroplane) was a fourth generation multi-role combat aircraft programme that was to be built by Yugoslav aircraft manufacturer SOKO. The Avion featured a cropped delta- canard configuration and was to be capable of achieving supersonic speeds under a combat configuration. The Avion shared several areas of commonality with French company Dassault Aviation's Rafale fighter aircraft; France had provided considerable technical assistance to Yugoslavia during the course of the Avion programme. Development work on the fighter was undertaken by the ''Vazduhoplovno Tehnički Institut'' (VTI) ( Aeronautical Technical Institute) of Belgrade, the former Yugoslavia's main military-technical institute, in cooperation with Dassault Aviation. Upon its entry to service with the Yugoslav Air Force, which was anticipated to occur during the late 1990s to early 2000s, the Avion would have been used as a replacement for the nation's ag ...

Maiden Flight
The maiden flight, also known as first flight, of an aircraft is the first occasion on which it leaves the ground under its own power. The same term is also used for the first launch of rockets. The maiden flight of a new aircraft type is always a historic occasion for the type and can be quite emotional for those involved. In the early days of aviation it could be dangerous, because the exact handling characteristics of the aircraft were generally unknown. The maiden flight of a new type is almost invariably flown by a highly experienced test pilot. Maiden flights are usually accompanied by a chase plane, to verify items like altitude, airspeed, and general airworthiness. A maiden flight is only one stage in the development of an aircraft type. Unless the type is a pure research aircraft (such as the X-15), the aircraft must be tested extensively to ensure that it delivers the desired performance with an acceptable margin of safety. In the case of civilian aircraft, a new typ ...

Turbo-Union RB199
The Turbo-Union RB199 is a turbofan jet engine designed and built in the early 1970s by Turbo-Union, a joint venture between Rolls-Royce, MTU and Aeritalia. The only production application was the Panavia Tornado. Design and development The RB199 originated with a requirement, in 1969, to power a new European multirole combat aircraft(MRCA) called the Panavia MRCA. The engine requirements to meet the Panavia MRCA specification were significant advances over current engines in thrust-to-weight ratio, fuel consumption and size. The final selection of the engine for the MRCA was made between a new European collaboration, Turbo Union, with the RB199, and Pratt & Whitney who proposed the JTF16. The Panavia MRCA would later be called the Panavia Tornado. Advanced engine studies at Bristol Siddeley had already been done to support the BAC/Dassault AFVG and were based on the Pegasus two-spool arrangement. At Rolls-Royce, where the three spool RB211 engine was in development, 3 shaft ...

General Electric F404
The General Electric F404 and F412 are a family of afterburning turbofan engines in the class (static thrust). The series is produced by GE Aviation. Partners include Volvo Aero, which builds the RM12 variant. The F404 was developed into the larger F414 turbofan, as well as the experimental GE36 civil propfan. Design and development F404 GE developed the F404 for the F/A-18 Hornet, shortly after losing the competition for the F-15 Eagle's engine to Pratt & Whitney, and losing the Lightweight Fighter (LWF) competition to the Pratt & Whitney F100 powered YF-16. For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from .20 to .34 to enable higher fuel economy. The engine was designed with a higher priority on reliability than performance. Cost was the main goal in the design of the engine. GE also analyzed "throttle profiles" and found that pilots were changing throttle settings far more often than enginee ...

Trailing Edge
The trailing edge of an aerodynamic surface such as a wing is its rear edge, where the airflow separated by the leading edge meets.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 521. Aviation Supplies & Academics, 1997. Essential flight control surfaces are attached here to control the direction of the departing air flow, and exert a controlling force on the aircraft. Such control surfaces include ailerons on the wings for roll control, elevators on the tailplane controlling pitch, and the rudder on the fin controlling yaw. Elevators and ailerons may be combined as elevons on tailless aircraft. The shape of the trailing edge is of prime importance in the aerodynamic function of any aerodynamic surface. George Batchelor has written about: :“ ... the remarkable controlling influence exerted by the sharp trailing edge of an aerofoil on the circulation.”Batchelor, G. K. (1967), ''An Introduction to Fluid Dynamics'', p.438, Cambridge University Press. ...

Strake
On a vessel's hull, a strake is a longitudinal course of planking or plating which runs from the boat's stempost (at the bows) to the sternpost or transom (at the rear). The garboard strakes are the two immediately adjacent to the keel on each side. The word derives from traditional wooden boat building methods, used in both carvel and clinker construction. In a metal ship, a strake is a course of plating. Construction In small boats strakes may be single continuous pieces of wood. In larger wooden vessels strakes typically comprise several planks which are either scarfed, or butt-jointed and reinforced with a butt block. Where the transverse sections of the vessel's shape are fuller, the strakes are wider; they taper toward the ends. In a riveted steel ship, the strakes were usually lapped and joggled (one strake given projections to match indentions in the one adjoining), but where a smoother finish was sought they might be riveted on a butt strap, though this w ...

Close Air Support
In military tactics, close air support (CAS) is defined as air action such as air strikes by fixed or rotary-winged aircraft against hostile targets near friendly forces and require detailed integration of each air mission with fire and movement of these forces and attacks with aerial bombs, glide bombs, missiles, rockets, autocannons, machine guns, and even directed-energy weapons such as lasers.''Close Air Support''. United States Department of Defense, 2014. The requirement for detailed integration because of proximity, fires or movement is the determining factor. CAS may need to be conducted during shaping operations with Special Operations Forces (SOF) if the mission requires detailed integration with the fire and movement of those forces. A closely related subset of air interdiction (AI), battlefield air interdiction, denotes interdiction against units with near-term effects on friendly units, but which does not require integration with friendly troop movements. The ter ...
