Martin Jetpack - Description

Description

The Jetpack is a small VTOL device, with two ducted fans that provide lift. It is powered by a 2.0 litre V4 piston 200-horsepower gasoline (premium) engine. The pilot straps onto it and does not sit. The device is too large to be worn while walking, so it cannot be classed as a backpack device. It does not have a jet turbine or rocket motor; the "Jet" in "Jetpack" refers to the production of two jets of air from its ducted fans. The Martin Jetpack does not meet the Federal Aviation Administration's classification of an ultralight aircraft; it meets weight and fuel restrictions, but cannot meet the power-off stall speed requirement. It uses the same gasoline used in cars, is relatively easy to fly, and is cheaper to maintain and operate than other ultralight aircraft. Most helicopters require a tail rotor to counteract the rotor torque; this and the articulated head complicate flying, construction and maintenance enormously. The Jetpack is designed to be torque neutral – there is no tail rotor, no collective, no articulating or foot pedals – and this simplifies flying dramatically. Pitch and roll are controlled by one hand, yaw and the throttle by the other.

Famous quotes containing the word description:

    Whose are the truly labored sentences? From the weak and flimsy periods of the politician and literary man, we are glad to turn even to the description of work, the simple record of the month’s labor in the farmer’s almanac, to restore our tone and spirits.
    Henry David Thoreau (1817–1862)

    It [Egypt] has more wonders in it than any other country in the world and provides more works that defy description than any other place.
    Herodotus (c. 484–424 B.C.)

    He hath achieved a maid
    That paragons description and wild fame;
    One that excels the quirks of blazoning pens.
    William Shakespeare (1564–1616)
