إن مارتن جيت باك هي طائرة تجريبية. والاسم التجاري يدعوها حزمة طائرة ، ولكنها ليست طائرة أوصاروخ يدار بالطاقة. It has been developed by the Martin Aircraft Company of New Zealand, and was unveiled on July 29, 2008 at the Experimental Aircraft Association's 2008 AirVenture in Oshkosh, Wisconsin, USA. It is classified by the Federal Aviation Administration as an experimental ultralight airplane.

Unlike earlier devices called "jetpacks", the Martin Jetpack is the first to be considered a practical device. It has been under development for over 27 years and uses a gasoline (premium) engine with two ducted fans to provide lift. Theoretically it can reach a speed of 60 miles per hour, an altitude of 8,000 feet, and fly for about 30 minutes on a full fuel tank. The consumer price is expected to be $100,000. Martin Aircraft planned to deliver the first jetpacks to ten customers in early 2010.

Description

The Jetpack is a small VTOL device, with two ducted fans that provide lift. It is powered by a 2.0 litre V-4 piston 200-horsepower gasoline (premium) engine. The pilot straps him/herself onto it, and does not sit. It is much too big for him/her to walk about wearing it, so it cannot be classed as a backpack device. It does not have a jet turbine or rocket motor, however the Jet in Jetpack refers to the production of two jets of air from its ducted fans. The Federal Aviation Administration has classified it as an experimental ultralight airplane. 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.
