Telegraph.co.uk mistakes small drone for UFO!

3689437243?profile=originalThat is just too funny! A post from UK newspaper Telegraph has the title: Russian protesters film UFO over Moscow and show a video with a small hexcopter drone, that shoot video like this

"Clearly not a helicopter, the silent UFO pulsated coloured lights and had five extended tendrils or pylons emanating from the body of the vehicle.."

Sounds spooky :P

Video and the full post: http://www.telegraph.co.uk/news/newstopics/howaboutthat/ufo/8951086/Russian-protesters-film-UFO-over-Moscow.html

RC Avatar-like twin rotor heli from flite test


What do you think about that? It is similar in concept with the helicopters from the movie Avatar, it uses differential thrust and independent tilt for each rotor. It doesn't look very stable but this looks like a very primitive prototype. Maybe it has the potential for something quite cool.

The now famous Flying Machine Arena from Swiss Federal Institute of Technology in Zurich (ETHZ) uploaded another video. This time they demonstrate the ability of the system to learn through practice. By using data from past experiments the quad is able to follow the exact trajectory given as a target, even if there are changes to the environment like the demonstration with the wind gust from the fan.

20 mach UAV - DARPA Falcon HTV2


Today DARPA will launch the second HTV2 that explores the 20mach region. It is launched aboard a Minotaur IV rocket and after re-entering Earth's atmosphere it glides until its destruction. At this altitude 20 mach translates to 13.000mph and DARPA states that the control system is one of the three key technical areas of the program (along with aerodynamics and heat management). The first flight was in April and after 9min communication was lost.

You can follow the launch live from @DARPA_News on twitter with the tag #HTV2


The video above shows a simulation of the complete flight (via robotpig.net )

EOLE - unmanned aerial launch platform

This is a scaled model for Eole, a french project under CNES on developing an unmanned aerial platform for launching rockets. This scaled model (1/2.2) is evaluating the flight dynamics and by next year rocket launches will take place in a specialized facility by the full version. It will be fully autonomous apart from the take-off and landing and it will operate within a 30km range. It looks like Scaled Composites White Knight 1 but it is much smaller.

The "Flying Ball"!

This flying ball is invented by Sato Humiyuki and developed by the Japanese TRDI. It is very stable and robust. It has a single propeller and downstream control vanes. Maybe it cannot do advanced aerobatics like a quad but it is very simple and could be better at most applications, especially in urban environment or indoors.

Air Force UAVs: The Secret History

I just read a great post by Bill Sweetman on Aviation Week's Ares Blog about a publication of The Mitchell Institute over the history of UAVs in the US armed forces.

The author is Dr. Thomas P. Ehrhard and although I haven't finished reading it yet it certainly is very interesting.

You can download the full document (88 page pdf) here: Air Force UAVs: The Secret History
