This Jetpack consists of a built-in gasoline engine driving twin ducted fans which produce sufficient thrust to lift the aircraft and a pilot in vertical takeoff and landing, enabling sustained flight.
Since the beginning of time man has dreamed of personal flight – the ability to fly as free as birds and escape gravity’s pull.
From the 1920s this dream has been refined in film, books and television, with the jetpack portrayed as the ultimate tool for the freedom of flight.
In the 1950s the first serious attempts at building a jetpack produced the Bell Rocket Belt. But the Bell Rocket Belt has some limitations. It is powered by an expensive and hazardous fuel, needs a light weight pilot, is incredibly hard to fly, and, after 50 years of development can only fly for 30 seconds. It is not the practical jetpack the world has been waiting for.
In 1981, as a New Zealand student, started his quest to a build a jetpack that overcame the limitations of the Rocket Belt. With enthusiasm and commitment Glenn has been able to capture the support of a large network of experts who shared his dream.
The rest is history. On 29 July 2008, the world’s first practical jetpack, was revealed to the world and became an international media sensation.
The Jetpack is constructed from carbon fiber composite, has a dry weight of 250 lbs (excluding safety equipment) and measures 5 ft high x 5.5 ft wide x 5 ft long. It’s driven by a 2.0 L V4 2 stroke engine rated at 200 hp (150 kw), can reach 8000 ft (estimated) and each of the two 1.7 ft wide rotors is made from carbon / Kevlar composite.
There is always risk associated with flying so the Aircraft has been careful to equip the pack with redundant systems that will take over in the event that the main system goes down. If a crash-landing is required, a pilot-operated toggle will rapidly fire a small amount of propellant deploying a ballistic parachute (similar to a car airbag) which will allow the pilot and jetpack to descend together. It also has an impact-absorbing carriage, patented fan jet technology and 1000 hours engine TBO (Time Between Overhaul). Small vertical take-off and landing aircraft (VTOL) are not subject to the same limitations as other helicopters and fixed wing aircrafts but Aircraft have built it to comply with ultra light regulations and therefore suggest it as at least as safe to operate, and claim it is the safest of all jetpacks yet built.
The Jetpack achieves with 30 minutes of flight time and is fueled by regular premium gasoline.
A roll cage is a specially constructed frame built in (or sometimes around) the cab of a vehicle to protect its occupants from being injured in an accident, particularly in the event of a roll-over. A roll bar is a single bar behind the driver that provides moderate roll-over protection. Due to the lack of a protective top, some modern convertibles utilize a strong windscreen frame acting as a roll bar. Also, a roll hoop may be placed behind both headrests, which is essentially a roll bar spanning the width of a passenger’s shoulders.
Factor Of Safety:
The Jetpack has a number of mechanical things moving fast….a drive train, Fan jets. All these are designed with far higher "factors of safety" (FOS) than is normal for an aircraft. This was done because of the newness of the design and to cover for unforeseen factors. For instance the Fan blades have a FOS of 5, at the hub and over 10 at the blade.
Production versions of the Jetpack are equipped with a Ballistic Parachute system from Ballistic Recovery Systems. This enables the pilot to be saved from a catastrophic failure down to a reasonably low altitude. Ballistic parachutes can open at very low altitudes, particularly if the aircraft has some forward speed. For this reason the "flight profiles" will be calculated to have the lowest risk possible.
Defense and recreation, with numerous applications in each sector.
