Barracuda Demonstrator Unmanned Air Vehicle, Europe
Barracuda Demonstrator Unmanned Air Vehicle, Europe
(NSI News Source Info) August 30, 2008: The Barracuda demonstrator unmanned air vehicle has been developed by EADS Military Air Systems in Germany and Spain, with an industrial team of about 30 aerospace companies and specialised suppliers. The air vehicle has a radius of action of more than 200km and a maximum speed over Mach 0.6. The operating ceiling is 20,000ft.
The purpose of the Barracuda demonstrator is to demonstrate and test technologies for future agile, autonomous and network-capable UAV systems.
The first flight of the air vehicle took place in April 2006 at the San Javier Military Air Base in southern Spain. During one of the flight trials in September 2006, the Barracuda air vehicle crashed into the sea.
Barracuda construction
The demonstrator air vehicle, including swept wings, is of entirely carbon-fibre construction. The air vehicle, of length 8.25m and wingspan 7.22m, has a maximum take-off weight of 3,250kg. The vehicle has a swept horizontal tail and outwardly canted fins and rudders.
"The Barracuda demonstrator unmanned air vehicle has been developed by EADS."
EADS Military Air Systems at its Augsburg (Germany) site is responsible for the manufacturing of the fuselage and EADS Military Air Systems in Getafe (Spain) for the construction and manufacturing of the swept wings. The air vehicle fuselage is manufactured using the vacuum assisted process (VAP) developed by EADS.
Liebherr is responsible for the design and supply of the air vehicle's electro-mechanical actuation control system.
The Liebherr primary fly-by-wire and the secondary flight control systems provide an all-electric-aircraft capability for the Barracuda in flight.

Fly-by-wire and flight control systems provide an all-electric-aircraft capability for the Barracuda in flight.
The Barracuda air vehicle is of entirely carbon-fibre construction with a maximum take off weight of 3,250kg.
The Barracuda carries a maximum payload of 300kg.
Avionics
For reliability and safety the Barracuda has a triplex flight control and navigation system. The avionics system installed has an open and modular configuration which will allow the installation of new sensors and communications equipment.
The flight control computer is provided by MTU and the navigation system by Thales.
Payloads
The Barracuda carries a maximum payload of 300kg. The avionics system will support communications for network-enabled operations and real-time transmission of information, including broadband line-of-sight.
In the future it may support beyond line-of-sight data links, secure and jam resistant crypto-links, multifunctional information distribution system (MIDS) / Link 16 NATO tactical data link, and a satellite communications link.
Payload systems will include infrared and other electro-optical sensors and, for future applications, it may include laser target designators, a high-accuracy emitter location system (ELS) and synthetic aperture radar (SAR). Barracuda may also be capable of carrying weapon systems. The systems are installed in the central payload bay.
Turbofan engine
The Barracuda air vehicle is powered by a P&W Canada JT15D-5C turbofan engine which provides 14.2kN thrust. The position of the engine's air intake as part of the dorsal surface and the profile of the air intake contribute to the low radar signature of the air vehicle.
"Barracuda demonstrates and tests technologies for future agile, autonomous and network-capable UAV systems."
Landing gear
The aircraft uses a conventional wheeled take-off and landing gear. Eaton is responsible for the design and supply of the hydraulic power system and the actuators for lowering and retracting the landing gear and for steering the nose wheel. The demonstrator air vehicle is a fully electric aircraft in flight and the hydraulics systems are used only for the landing gear actuation and nose wheel steering.
The air vehicle is fitted with E-brake electrically operated carbon brakes developed by Meggitt's Dunlop Aerospace Braking Systems. The E-brake is a reduced-weight, high-reliability braking system for manned and unmanned aircraft.
Mission control station
A ground-based mission control station provides mission planning, monitoring and data evaluation. The air vehicle operates completely autonomously. During flight, high level commands can be entered to change pre-planned missions.
The entire system of the control station and air vehicles has a small logistical footprint, so the system is easy to operate and deploy.





China aids Iran's tactical missile programme

(NSI News Source Info) August 30, 2008: China is producing several families of tactical guided missiles, primarily for the anti-ship role, that appear to have been designed and developed for a single export customer - Iran. At the China Air Show 2004, in Zhuhai during late October and early November, the Hongdu Aviation Industry Group, exhibited three variants of two new missiles - the JJ/TL-6B, JJ/TL-10A and KJ/TL-10B. These weapons are identical to Iranian missiles known as Nasr (TL-6) and Kosar (TL-10). Brochures produced by the Iran Aerospace Industries Organisation (IAIO) appear to carry photos of even the same models exhibited in China, labelled with Iranian programme names. It is now clear that two missile programmes revealed a few years ago by China National Aero Technology Import & Export Co (CATIC) - the FL-8 and FL-9 - were the TL-10 and TL-6, respectively, under yet another name. A third weapon exhibited at Zhuhai and destined for Iran was a new variant of the China Aerospace Science and Industry Corporation (COSIC) C-701 anti-ship missile, the radar-guided C-701R. The C-701 has previously been presented by the IAIO in Iran, where it is claimed as a national programme Of the newly unveiled missiles the smaller KJ/TL-10 series appears to have made the most progress. Development work began during the mid-1990s and Hongdu publicity material from Zhuhai shows a TL-10 being fired from an unidentified naval ship. A Hongdu spokesperson told JDW that deliveries of the TL-10A variant were already under way to a foreign customer. It was stressed that both the TL-6 and TL-10 programmes are for export and not for national use. The officials added that the radar-guided TL-10B and TL-6B missiles were still in development with perhaps another two years remaining until they were operational. Conflicting accounts were given as to whether the missiles are, or will be, both air- and surface-launched. The Chinese abbreviation KJ indicates an air-to-ship missile (Kong Jian), while the JJ designator is for a surface-to-surface weapon (Jian Jian). The TL (Dragonfly) name identifies the missile family within Hongdu, a unit of China Aviation Industry Corporation II (AVIC II). JDW was told that the radar-guided TL-10B would be a helicopter-launched weapon, while an air-launched version of the TL-6 was also part of that missile's development plan. Helicopters were identified as the platform for an air-launched TL-6, but elsewhere at the show AVIC I displayed a model of the Shenyang F-8IIM carrying TL-6 missiles. The latest C-701R missile from COSIC, the parent company of the better-known China Precision Machinery Import Export Co, CPMIEC, is fitted with a radar seeker (believed to be a millimetre wave radar) replacing the earlier electro-optical seeker of the C-701T. Effective range now stands at 25 km. The C-701R has been redesigned with a longer missile body and the deletion of the pop-out fin tips found on the C-701T. The size, shape and general performance of the C-701 is very similar to that of the TL-10 series. Both weapons are clearly intended for Iran but it is not known why two apparently competing designs have evolved for the same customer. Iranian sources show that both the TL-10 and C-701 missiles are included within the national Kosar programme. Chinese industry representatives at Zhuhai declined to comment on links with Iran.
