Ein nichtssagender Artikel.The D-Dalus signals a new generation of aircraft design
(5. Dezember 2013)
The D-Dalus 1, developed in 2006, has a wingspan of 1.7m and weighs 20kg. D-Dalus 2 first flew in 2012, and carries a payload of 100kg. The team aims to turn this into sustained, manoeuvrable flight, with wind--tunnel and then flight tests in summer 2014.
The cyclogyro can be controlled remotely, but IAT21 is also developing autonomous guidance software.
According to Wills, scaling up the design even further looks straightforward, and his plans include a light passenger-aircraft in the next ten years.

D-Dalus VTOL UAV with Cyclogyro drive
D-Dalus combines the flight characteristics of a helicopter and a fixed wing aircraft
The company is seeking cooperation partners or end customers in order to develop this aircraft further. The technology is scalable, permitting a wide range of applications as a UAV and for manned aircraft.

Die DARPA hat derzeit einen Wettbewerb für neuartige VTOL-Konzepte laufen - und die bekannten Vorschläge großer Unternehmen, die in diesem Rahmen entwickelt werden, sind - um es mal so auszudrücken - einfach enttäuschend. Wirkliche Innovation ist da nicht zu erkennen - eher das Aufwärmen alter Ideen:
Vertical Takeoff and Landing Experimental Plane (VTOL X-Plane)
VTOL X-Plane challenges industry and innovative engineers to create a single hybrid aircraft that would concurrently push the envelope in four areas:
◦ Speed: Achieve a top sustained flight speed of 300 kt-400 kt
◦ Hover efficiency: Raise hover efficiency from 60 percent to at least 75 percent
◦ Cruise efficiency: Present a more favorable cruise lift-to-drag ratio of at least 10, up from 5-6
◦ Useful load capacity: Maintain the ability to perform useful work by carrying a useful load of at least 40 percent of the vehicle’s projected gross weight of 10,000-12,000 pounds
Sikorsky's Rotor Blown Wing -- Look Familiar? (19. Dezember 2013)
When I first saw Sikorsky's Unmanned Rotor Blown Wing concept for DARPA'S VTOL X-Plane program, it reminded me of something. But I couldn't remember what, so I sought expert help. And the answer? It's Boeing's Heliwing - a tailsitter VTOL unmanned aircraft that flew, briefly, in 1995.
Heliwing was funded by the Pentagon's UAV Joint Program Office (remember that?). It was a 17ft-span, 1,450lb gross-weight UAV with two 7ft-diameter proprotors powered by a single 240shp Williams WTS117 turboshaft. The Heliwing was intended to reach 180kt in forward flight and carry a 200lb payload for 5hr. The sole example first flew in April 1995, but crashed in July when the engine flamed out and the program was shelved.
Sikorsky is working on conceptual and preliminary design of the Unmanned Rotor Blown Wing with Lockheed Martin Skunk Works under a 22-month, $14.4 million VTOL X-Plane Phase 1 contract. DARPA is expected to award up to four Phase 1 contracts. Aurora Flight Sciences has one, but isn't saying what its design looks like. And Boeing is tipped to get one for its Phantom Swift ducted-fan design (seen below). DARPA plans to pick one design to fly in 2017.

FLIGHT INTERNATIONAL, 1 - 7 June, 1994 hat geschrieben:Boeing picked for UAV demonstration
The Unmanned Aerial Vehicle Joint Programme Office (UAV JPO) has picked Boeing to demonstrate a vertical - launch - and - recovery (VLAR) UAV. The selection surprised industry officials, who had thought that multiple awards would be made with
one going to Bell Helicopter Textron to further demonstrate its Eagle Eye tilt-rotor UAV.
The one-year contract is worth about $2 million. The Heliwing UAV is being developed by Boeing engineers in Seattle and at Boeing Helicopters. The tail-sitter air vehicle features a fixed-wing and a pair of 2m-diameter counter-rotating Propellers coupled to a 30kW (40shp) Williams International WTS-117 turbine engine.
The Heliwing takes off and lands in the helicopter mode. Following take-off, speed is increased in the horizontal direction while in rotary mode. It then pitches/rolls over into a horizontal flight attitude. The reverse is true for landing.
With a gross weight of 375kg, it carries 45kg of fuel and has a mission endurance of 1.5h. One full-size Heliwing VLAR demonstrator has been built. It is due to undergo windtunnel testing at Boeing Helicopters in July. Industry officials say that there were as many as nine VLAR bids were received, including another counter-rotating tail-sitter design from Dornier.
Kaman Aerospace is thought to have offered its Spyglass, a family of intermeshing-rotor UAVs scaleable in size and gross weight to between 545kg and 5,540kg.
It is thought that funding constraints prompted only a single VLAR award. The UAV JPO may have also felt that the
tilt-rotor UAV has been adequately demonstrated in the Eagle Eye programme.
Phantom Swift: Putting rapid into rapid prototyping (11. September 2013)
The Defense Advanced Research Projects Agency (DARPA) is looking for a vertical takeoff and landing (VTOL) aircraft that can fly fast, hover efficiently and carry a lot of cargo. Thanks to rapid prototyping, a team of Boeing Phantom Works engineers in Philadelphia designed and built a flying subscale model of the innovative Phantom Swift in time to be part of Boeing's proposal for DARPA's vertical takeoff and landing X-Plane competition.
The DARPA vertical takeoff and landing aircraft X-Plane program will have three phases. Phase I will last 22 months, with several competitor designs partially funded by DARPA. Only one consolidated Phase II/Phase III contract for fabrication and flight demonstration contract will be awarded, with a goal for a first vertical takeoff and landing X-Plane flight within 47 months.
The first phase of DARPA’s X-Plane program is expected to begin in the next few months.
Aurora Flight Sciences hat vor beinahe fünf Jahren eine VTOL-Drohne getestet. Diese ist dann in der Versenkung verschwunden. Sie steht angeblich noch im Entwicklungsstadium:
Exclusive: Aurora Flies VTOL Excalibur (17. Juli 2009)
Excalibur is under development at Aurora as a purpose-built armed, tactical UAV.
Excalibur uses a turbine-electric hybrid propulsion system to give the aircraft VTOL capability while also allowing use of the turbine engine for horizontal flight. The aircraft's advanced flight control system operates with a high level of autonomy. Because the aircraft does not rely on a remote pilot, operators are free to focus on mission planning and finding and engaging targets instead of flying the aircraft.
Excalibur combines VTOL launch and recovery, high-speed flight (up to 400knots), and low speed loiter (100 knots) into one aircraft. Excalibur can operate in a Short Take Off and Landing (STOL) or Short Take Off and Vertical Landing (STOVL) mode for increased mission durations or payloads.
Ich bin schon gespannt, wann die in London präsentierte Version des D-DALUS auf den Markt kommen bzw. wann sie überhaupt den Jungfernflug absolvieren wird?
