Test of laser from C-130H melts hood of car: "New video released by the Air Force and Boeing Co. show what happens when a C-130H Hercules aims the Advanced Tactical Laser at the hood of car.In the video recorded Aug. 30 during a test flight at Kirtland Air Force Base, N.M., the laser melts the hood and sparks a fire. A press statement from Boeing said the laser ‘killed the vehicle.’The weapon uses a chemical laser that fills the cargo hold of C-130 to produce a laser beam fired from a turret mounted in the belly of a C-130.
If the size of laser can be reduced, the Air Force could one day fly laser versions of the AC-130 gunships.The future of the project is in doubt as it competes for funding with other weapons, but a Boeing official said he is optimistic.‘The bottom line is that ATL works, and works very well,’ Gary Fitzmire, program director of Boeing Missile Defense Systems' Directed Energy Systems unit, said in a release. ‘ATL's components — the high-energy chemical laser, beam control system and battle manager — are performing as one integrated weapon system, delivering effective laser beam energy to ground targets.’Working with Boeing on the $200 million project, which began in 2002, is the Air Force Research Lab’s Directed Energy Directorate.

Wright Flyer replica crashes, ceremony canceled: "WRIGHT-PATTERSON AIR FORCE BASE, Ohio — An authentic replica of the 1905 Wright Flyer III crashed Thursday morning, leaving its pilot seriously injured and forcing the cancellation of a ceremony scheduled for Oct. 5.Vintage aircraft builder and pilot Mark Dusenberry was flown to Miami Valley Hospital in Dayton. Following the crash, Dusenberry was conscious and communicating his injuries to paramedics at the Huffman Prairie Flying Field, said Park Ranger Nicholas Georgeff with the Dayton Aviation Heritage National Historical Park.Dusenberry, an engineer from Dennison, was practicing for the 104th Anniversary of Practical Flight ceremony that had been planned for next week. The flight was to be a re-enactment of a historic flight made by Wilbur Wright 104 years earlier.Air Force safety, airfield operations and crash rescue personnel were on scene at the time of the crash, rehearsing for possible mishaps on the day of the ceremony, said Dave Egner, director of special operations with the 88th Operations Support Squadron at Wright-Patterson.Georgeff said Dusenberry made a ‘picture perfect’ successful straight and level practice flight at 9 a.m. that lasted approximately 22 seconds. Launch for the second flight at 9:30 a.m. was normal, but the aircraft started to oscillate vertically – a fairly common experience among early flights by the Wright brothers – then plunged about 20 feet to the ground, Georgeff said. The aircraft was about 19 seconds into its second flight when it crashed.Safety investigators with the FAA’s Cincinnati Flight Standards District Office arrived on scene shortly after the crash and are investigating the cause."

VIDEO: Samarai - Lockheed's Maple-Seed UAV: "Lockheed Martin's Advanced Technology Laboratories is flight-testing a mono-wing rotorcraft, or monocopter, inspired by the maple seed, or samara, and called the Samarai. The aircraft tested earlier this year is a far cry size-wise from the design developed for DARPA's Nano Air Vehicle (NAV) program - that had a wingspan of just 7.5cm, this one is about 30in - but it is being used to develop the flight controls for eventual backpack- or pocket-sized versions that could be launched through a window to fly indoors.

Lockheed was not selected to go forward with the NAV program - DARPA selected a flapping-wing design from AeroVironment - in part because of the challenges in the design, with its monocopter aerodynamics, tip-jet propulsion and rotating-camera guidance, navigation and control (GNC). But the simplicity of the concept compared with other micro and nano UAVs is compelling, and Lockheed has continued to fund research work at ATL.
The 30in-span electrically powered model, several of which were built cheaply using off-the-shelf components, is an easier scale to work with initially, and has enabled development and testing of the flight control system required to operate a monocopter. It has also allowed the propulsion issue to be worked separately from guidance and control.Photo: Lockheed Martin
The next step is a 20-30cm-span 'superscale' prototype, expected to fly towards the end of the year, that will be used for GNC testing, with the goal of demonstrating non-GPS and indoor flight. These vehicles will fly initially with a propeller turning the monowing, but Lockheed says reaction-drive propulsion will be integrated later.
The non-GPS indoor GNC uses the images from fixed cameras on the rotating UAV and the phenomenon of optical flow to provide the data required for flight control. The same cameras provide imagery to the operator. Lockheed is looking at what other sensors, including acoustic, could be added to help with flying and navigating indoors.
Lockheed has a seedling contract from DARPA, called Katana, to study larger applications of the monocopter concept, but the Samarai program is focused on going smaller, down to a few inches for flight indoors, where the monowings simplicity and robustness are seen as having most value."
