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:
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
—Horace Walpole (1717–1797)
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
