Human-powered helicopter record

July 2, 2012 by Tim McAdams

In 1980 the American Helicopter Society offered a $250,000 prize for the first human powered helicopter. Known as the Sikorsky Prize, it was named in honor of the late helicopter pioneer Igor Sikorsky. To win the prize, the aircraft must reach a height of three meters and remain airborne for 60 seconds while staying in a 10 meter square.

 Although some attempts have been made, so far 32 years later the prize has not been won. The first helicopter to try to win the contest was the Da Vinci III in 1989, designed and built by students at Cal Poly San Luis Obispo in California. It flew for 7.1 seconds and reached a height of 8 inches (20 cm). The second was the Yuri I in 1994, designed and built by students at Nihon University in Japan. It flew for 19.46 seconds and reached an altitude of 20 cm.

On June 21, 2012 a team of engineering students from the University of Maryland’s A. James Clark School of Engineering have gotten the closest to wining the prize and achieved an unofficial world record of 50 seconds with their Gamera II human-powered helicopter, far surpassing any previous records. It will not become official until validated by the National Aeronautic Association. The pilot was Kyle Gluesenkamp, a Ph.D candidate at the school’s mechanical engineering department.

The first version (the Gamera I) stayed airborne for 11.4 seconds. The aircraft was re-engineered with improved airfoils and a new structural design that reduced weight by 39 percent. As with the previous version, the pilot produced power by pedaling. However, the Gamera II has hand cranks that can increase power output by as much as 20 percent. However, due to additional exertion required by the pilot, the output gains drop off after about 60 seconds. The Gamera II is about 105 feet from tip to tip and weighs about 75 pounds without a pilot.

    Unless I’m misunderstanding, Gamera II would not appear to even be qualified for the Sikorsky because it’s 105′ x 105′ dimensions would be impossible to maintain within a “10 meter square.”

  2. Alan Barnes Says:

    I don’t think the craft needs to *fit* within a 10 meter square. It just can’t move outside of a 10 meter square….more than approx 15′ in any direction from it’s starting point

  3. Kris Maynard, NAA Official Says:

    Alan, you are correct. The vertical axis of the center-most point of the aircraft must stay within the specified boundaries.

    Implausible human factor Vs weight and wind might work inside a large hanger.

    How about this, if not prohibited. Using an aircraft like the one here, Incorporate a methodology of storing ,call it the primary energy generated by the human ,before take off .( eg like a flywheel of sorts. ) then when the appropriate amount of primary energy is stored , it can be used along with ,say, the additional human generated, call it the secondary, energy( via peddles etc). This secondary human generated energy would begin feeding energy into the aircraft and that energy along with the stored primary energy could be used to keep the aircraft up for the duration needed to accomplish the feat for the prize.

    I think they should install rubber bands that are wrapped by the human power plant. They could then be released. Technically the bands gain their energy through human power and could be supplemented by additional pedaling power. I says this without a reference to the rules.

    Not that I’m one to talk but it sounds like they need a bunch of super in shape individuals that can take that kind of exertion for 60 seconds. I’m always impressed with our younger generations skill set and ability to adapt.

    Practicing personal Bunk Beds is really important because if one wouldn t take care of your
    teeth. This savings alone for one visit more than paid for an individual alone due to certain medication side effects
    may make it difficult to fill the space.

    Normal reasons that computers get slower is because of low diskspace,low memory, and low memory. However there are apps that can solve such dilemas. Using these programs can really help. Might you tell me know if that is the case
