Multi rotor fan club

Regardez bien ce qu'il va filmer, c'est sympathique.

Tres sympa effectivement. On dirai une mini capsule spatiale

Ils appellent ca un lunar lander

C'est très mal filmé,

mais c'est quoi ce truc, et à quoi ça sert ?

D'abord le commentaire qui va avec la video.

<QUOTE>We've been using the ArduCopter platform at Marshall Space Flight Center for almost a year now. We started with a 3DR Quad and have several 3DR Hex vehicles. We're using them to test their capabilities for aerial reconnaissance as well as search and rescue. This past week we used our Quad with a GoPro Hero3 to film a test flight of the Robotic Lunar Lander. It was a fully autonomous flight (takeoff, ascent to 100' altitude, transit to loiter position, RTL once filming is complete, and landing). As you can see from the video, we got some amazing footage from a very unique vantage point. Thanks to 3DR and the devs for all your help and assistance!</QUOTE>

<QUOTE>Garrick and I are both civil servants with NASA. He works in the avionics group and I work in our propulsion group. We were given a little bit of play money to go work on UAV's and we do this stuff on the side. We have other people involved from other departments as well.

Also, the lander uses pressure fed hydrogen peroxide as a main propellant. It is pushed through a silver catalyst bed which creates a pretty intense reaction and heats up the propellant which is then expanded through a nozzle to produce thrust. Since it is a lunar lander, there is one main motor which is dedicated toward canceling ~5/6 of Earth's gravity in order to produce a similar gravitational environment that it would see on the moon. That way, all of the additional controls and thrusters can be tuned and sized in a manner that is ideal for its end mission, a trip to the moon! It is pretty neat project. You should follow them on Twitter!

.

Ils ont utilisé un vol autonome puis position loiter puis retour bercail automatique.

Donc, il dit dans son commentaire que cette machine est destiné à aller sur la lune

Une autre portion de video retravaillé mais je ne l'ai pas encore regardé

super, c'est un stand de tir de fusé a coter il me semble, ont vois le grand toboggan pour dirigé les flames non?
