helicopter

A helicopter (or chopper, helo or whirlybird) is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forwards, backwards, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft would usually not be able to take off or land. The capability to hover efficiently for extended periods of time allows a helicopter to accomplish tasks that fixed-wing aircraft and other forms of vertical takeoff and landing aircraft cannot perform.

A talented team of students from the University of Maryland’s Clark School of Engineering has set a new record for the longest flight time for a human-powered helicopter. The helicopter in question, called “Gamera II”, after the flying monster turtle of Japanese films and the university’s terrapin mascot, was devised and built by the students themselves. First thing that [...]

For most, a jetpack can be considered more of a SciFi concept than a viable, realistic flying contraction. However, recent advances from a New Zealand aeronautical company might have paved the way for jetpacks to finally become commercially mainstream. Exiting, right? Just recently this month, the aforementioned company, Martin Aircraft Co., has successfully tested one [...]
