Dubai Airshow 2011: Adcom unveils United 40 MALE UAV
Abu Dhabi-based Adcom used the Dubai Airshow to unveil its latest creation – the United 40 MALE UAV. The United 40 uses an unusual biplane configuration and a hybrid turbine-electric engine to enhance its endurance. The aircraft on display in Dubai is the first prototype and Ali Al Dhaheri, general designer and CEO at Adcom, said he hoped to fly the aircraft in the next three to four weeks.
'With most UAVs with a pusher propeller, the centre of gravity is towards the rear of the aircraft,' said Al Dhaheri, 'But with the two-wing configuration, we keep the centre of gravity in the middle of the aircraft. ‘The United 40 uses a patented design wing giving it a glide ratio of 1:43. That’s four times more than the glide ratio of the MQ-9 Reaper,' he added.
Al Dhaheri claimed that the wings allow the aircraft sustain cruise flight at a one-sixth of the aircraft's full engine power of 120 hp, provided by the Rotax 914 engine. The power of the electric motor, which is capable of producing 80 hp can be combined with the engine to give the aircraft 200 hp, boosting take-off performance in hot and high conditions.
The United 40, which has been named in celebration of the United Arab Emirates 40th anniversary, is also designed to be armed, capable of carrying up to eight Namrod air-to-ground missiles. The missiles feature fold out wings that deploy when the weapons are ejected from the aircraft. The weapons are carried on a rotary launcher.
Al Dhaheri says one of the design priorities was to keep design clean to improve aerodynamics – as a result even the aircraft's EO/IR sensor is retractable. Control operations can be done by satellite or line-of-sight. Al Dhaheri claimed the aircraft could fly for several days, although company literature suggests a more conservative but no less impressive 25 hours. The aircraft is 11m long and has a wing span of 17.5m.
If i had such a Big UAV with 3 Engines then i can too Stay over 100 Hours with over 200 Galons of Fuel.
But what happens if no more Fuel is there ? And why 3 Engines ? Hybrid Engines ? Not Easy to Repair ,we see that in the History ,what Ferdinand Porsche has tried.
IT´s not Flying ,it´s gliding !
I see on 23.000 Feet and a Payload with 200 - 400 KG , Someone here is lying !
