AOPA Hover Power » Blog Archive » Coaxial rotors - 0 views

  •  
    "coaxial rotors, uses a pair of helicopter rotors mounted one above the other to produce both lift and thrust. Sikorsky's high speed technology demonstrator the X2 uses this design as well as many Russian helicopters. To neutralize the torque, the rotors spin in opposite directions creating equal and opposite torques that cancel each other and eliminate the need for a tail rotor. Yaw control is achieved by increasing the collective pitch of one rotor and decreasing the collective pitch on the other. "

AeroVelo, University Of Toronto Team, Win Human Powered Helicopter Flight Competition - 0 views

  •  
    "human power, delivered to the craft's four rotors through the bicycle pedals he steadily pumps throughout his flight. It's that fragile machine, built by Reichert's Canadian team, which has now won a long-coveted international prize that lay unclaimed for years. The AHS Igor I. Sikorsky Human Powered Helicopter Competition was established in 1980 for the first successful controlled flight of a human powered helicopter that could reach a height of three metres while hovering for at least one minute in a 10-square-meter area."

UMD Robo Raven | Interesting Engineering - 0 views

  •  
    "new robotic bird, "Robo Raven", whose wings flap completely independently of each other, and also can be programmed to perform any desired motion, enabling the bird to perform aerobatic maneuvers. This is the first time a robotic bird with these capabilities has been built and successfully flown."

Skylon Spaceplane | Interesting Engineering - 0 views

  •  
    "project to take the Skylon spaceplane into the orbit. During most of time it would be used as a normal airplane, like taking off and landing on conventional runways, but the main difference is in the power source of this aircraft. It will be powered by a Sabre engine, specially designed for its purpose. It will be working like a normal jet engine in the lower attitude, breathing in oxygen and when in higher altitude of outer space it will act as a rocket engine. So, we may call it some sort of a "hybrid engine"."

UK sends hand-held helicopter drones to war zone (Update) - 0 views

    "newly issued Black Hornet miniature surveillance helicopter during an operation in Afghanistan. The Scandinavian-designed Black Hornet Nano weighs as little as 16 grams (0.56 ounces)-the same as a finch. The four-inch-long (10-centimeter-long) helicopter is fitted with a tiny camera which relays still images and video to a remote terminal. Troops used the drone to look for insurgent firing points and check out exposed areas of the ground before crossing."

New take on 'X' plane wins NASA grant - 0 views

  •  
    "Cleared for Mach 2 after departure, this supersonic jet of the future would yaw 90 degrees and put a new set of wings into the wind. The brainchild of Ge-Chen Zha of the University of Miami, the "supersonic, bi-directional flying wing" recently landed a $100,000 NASA grant to continue development of a concept that could cut the New York to Tokyo travel time to four hours-and perhaps significantly faster than that, Zha said."

NASA Concept Plane Designed to Fly Sideways - Core77 - 0 views

  •  
    "The "Supersonic bi-directional flying wing" has wings of alternating length at each compass point and therefore can solve both situations, by taking off in one orientation, then essentially flying sideways when it's time to go supersonic. I'd like to see video of how this happens in motion, but from what I can see in the stills, it looks like the dual engines up top determine the direction of flight, and that the rest of the plane rotates around them.
