I would have to say that the YF-23 Black Widow be my favorite concept aircraft.

I find it a bit ironic that you would say that a forward swept wing fighter would cost too much money, and then post one of the ATF concepts.

that F-37 is beautiful! i want kisses from it! gimme kisses!

You all know that the f-37 is a prop for a new Jennifer Garner movie called Stealth right?

I mean come on a hyper mach sub orbital (or is the concept orbital?) bomber that can hit anytarget in the world in 3-4 hours.
How cool is that?

Yup. The Hypersoar project (which I believe was renamed a little while ago to something like Pheonix or Falcon) most certainly takes the cake for radical performance...

A 25-meter-long HyperSoar aircraft (about as long as the wingspan of a large business jet) could make a conventional takeoff from a standard runway. Using special air-breathing, rocket-based, combined-cycle engines, it would ascend to 40 kilometers-at the outer limit of Earth's atmosphere. Once there, its engines would be turned off, and it would coast up to a high point of 60 kilometers before beginning to fall back down to about 35 kilometers-well inside the atmosphere's upper level. As it descends into denser air, the aircraft would be pushed up by the increased aerodynamic lift. The engines would fire briefly, propelling the plane back into space. Outside the atmosphere, the engines shut off and the process repeats. In this way, HyperSoar would skip off the top layer of the atmosphere every two or so minutes, like a flat rock skittering in slow motion across the surface of a pond.

Inclusive of the time taken and distances covered by the ascent and descent portions of a flight, a trip from Chicago to Tokyo (10,123 kilometers) would involve about 18 skips and 72 minutes, and to travel from Los Angeles to New York (3,978 kilometers) would involve about 5 skips and take 35 minutes. (Both flights require a total of about 2,450 kilometers and 27 minutes for take off and landing.) By popping regularly out of the atmosphere and using the engines intermittently, HyperSoar would use less fuel and solve a critical problem that plagues other hypersonic aircraft designs-heat.

On 18 June 2004 a scene for the upcoming Columbia Tri-Star movie "Stealth" was filmed on the flight deck aboard the Nimitz-class aircraft carrier USS Abraham Lincoln (CVN 72). Lincoln was conducting local operations in preparation for an upcoming scheduled deployment after 10 months of dry docked Planned Incremental Availability (PIA). About 80 cast and crew members were aboard the Everett-based aircraft carrier to shoot scenes for the Columbia Pictures action film starring Josh Lucas, Jessica Biel and Sam Shepard, The $130 million film is expected to hit theaters in 2005.

According to the back story, the F/A-37 "Talon" is a Mach 3.5, super cruise stealth fighter/bomber/interceptor with a 4000nm range. Top speed is somewhere in the Mach 4+ range. The movie is premised on an artificial-intelligence program designed to fly jet aircraft and reduce human casualties. Not surprisingly, one of the AI robo-pilots runs amok when Navy officials decide to use an unmanned version of the “Talon”. When the plane begins attacking friendly forces, Navy pilots are called in to save the planet from artificial intelligence

Lockheed Martin reveals future strike platform
06 June 2003

Lockheed Martin has revealed images of a stealthy, supersonic strike aircraft designed to penetrate heavily defended airspace in the initial phase of a conflict and deliver precision-guided munitions on time- sensitive and other high-value targets.

The company developed the concept, which it refers to generically as the 'long-range strike aircraft', in support of studies on future strike platforms that the US Air Force Research Laboratory (AFRL) is leading.

Although the air force anticipates operating its current bomber force of B-1B, B-2A and B-52H aircraft until 2040, it is examining complementary capabilities. It is prioritising its technology investments to be in a position to launch a next-generation strike programme around 2012-15, with the goal of fielding the system starting around 2020. The system it chooses may not be an aircraft, but rather a capability that traverses space, or some other unconventional approach.

Nonetheless, the service is examining a range of notional subsonic, supersonic and hypersonic aircraft designs as it formulates its technology roadmap.

The Lockheed Martin aircraft is a M2.0-M4.0-class system with highly swept wings and large engines, said Kevin Renshaw, Lockheed Martin's programme manager for long-range strike and advanced combat aircraft. Crew would consist of a pilot and a weapons systems operator.

The company is examining a mix of payload and range options. A payload capacity between 15,000 lb and 40,000 lb (6,802kg and 18,140kg) is envisaged, Renshaw told Jane's Defence Weekly, noting that between 20,000 lb and 25,000 lb appears to be the preferred design trade space. The concept has a notional combat radius of 3,000 miles (4,827km) without mid-air refuelling.

Renshaw said the company believes that many of the key technologies exist today for such a system but need to be refined so that they are smaller, lighter and more affordable. The company has a heritage in developing supersonic aircraft like the M2.0-class B-58 Hustler bomber and M3.2-class SR-71 Blackbird reconnaissance aircraft.

One area Renshaw highlighted for improvement is the cruise efficiencies of supersonic engines so that they require only one-half to two-thirds the fuel of existing systems.

Now a few Russian concepts ..




The Mig I-2000 - Interceptor-2000 (Istribityel-2000)

The twin-engined Medium Combat Aircraft (MCA) is a stealthy Gen-5 combat aicraft optimised for strike missions. It will complement LCA and Su-30MKI as India's leading combat planes. It may fly before 2010 and be inducted by 2015. Right now its in design, prototype building stage

Propulsion
The State owned Gas Turbine Research Establishment [GTRE] was to indigenously develop the Kaveri engine to power the LCA and MCA. But there have been major slippages in all the milestones. GE, SNECMA, and Klimov had all offered to provide the engines for this aircraft.

The Kaveri engines in the MCA will have a slightly higher dry thrust than in the LCA engine. These engines will also have thrust-vectoring nozzles. It is unknown which company will be providing this technology, or whether it will be developed in India itself. A supercruise capability is not being sought. The twin engined aircraft is planned to have a thrust ratio of 7:8:1. The MCA will use India's own radar-absorbent material to reduce radar cross-section.

Kaveri
Air-mass flow 78 kg/s
By-pass ratio 0.16
Overall pressure ratio 21.5
Turbine entry temperature 1487-1700 K
Maximum dry thrust 52 kN (5302 kg)
Maximum dry SFC 0.78 kg/hr/kg
After burner maximum power thrust 81 kN (8260 kg)
After burner maximum power SFC 2.03 kg/hr/kg
Thrust-to-weight ratio 7.8

Kaveri engine is a two-spool bypass turbofan engine having three stages of transonic low pressure compressor driven by a single-stage low pressure turbine. The core engine consists of six-stage transonic compressor driven by single-stage cooled high pressure turbine. The engine is provided with a compact annular combustor with airblast atomisers. The aerothermodynamic and mechanical designs of engine components have been evolved using many in-house and commercially developed software for solid and fluid mechanics.

Kaveri three-stage transonic fan, designed for good stall margin and bird strike capability, handles an air mass flow of 78 kg/s and develops a pressure Combustion Chamber Liner ratio of 3.4. The six-stage variable capacity transonic compressor of Kaveri develops a pressure ratio of 6.4. The variable schedule of inlet guide vanes and two rows of stator is through FADEC control system to open the stator blades in a predetermined manner. High intensity low UD ratio annular combustor of Kaveri engine incorporates air blast injection of fuel for uniform outlet temperature profile and reduced carbon emission.

Kaveri high pressure turbine is provided with an efficient cooling design incorporating augmented convection-cum-film cooling for the vanes and combination cooling for the rotor blade to handle up to 1700 K turbine entry temperature. Kabini engine comprising high pressure compressor, combustor and high pressure turbine has undergone high altitude test at facilities abroad successfully demonstrating the flat rating concept of Kaveri engine assembly and in particular the combustor high altitude ignition and stability performances.

Kaveri engine has been specifically designed for Indian environment. The engine is a variable cycle-flat-rated engine in which the thrust drop due to high ambient, forward speed is well compensated by the increased turbine entry temperature at the spool Kabini altitude test speed. This concept has been already demonstrated with high temperature and pressure condition in DRDO's High Mach Facility. Kaveri engine is controlled by Kaveri full authority digital control unit [KADECU), which has been developed and successfully demonstrated at DRDO's test bed.

Stealth

Stealthiness will be a priority and hence the MCA will have two small, outward-canted fins and the external fuel tanks will be mounted above the wings. Absence of a vertical fin improves stealth. However, not all weapons will be internal and hence will compromize the stealth.

If all progresses according to plan, MCA will become first military fighter that has no tail - at all. USA is the only country to have seriously pursued such aircraft. It experimented with tail-less design in X-36. F-16X concept is another tail-less concept.

Tail-less design has been seen in Flying Wings, but these represent a separate class of aeroplanes. To realize the MCA, India will have to develop cutting edge technology.

Paste this in your address bad if the pic dose'nt showup

[edit on 7-2-2005 by Stealth Spy]

actually china are really working on the J-12

A prototype has alredy been built, here is a rare unclear pic

its rumoured that the chinese J-12 will be better than the PAK-FA, thanks to lots more funding.
