Q Branch - Bell Rocket Belts
In
about 1962 or 1963, Wendell F. Moore, an employee of Bell Aerosystems, in the
US, worked on a personal flight system which became know as the Rocket Belt. According
to some accounts, it was intended to be portable, and light enough for battlefield
use. Moore undertook a series of test flights on a tether (safety) line, his final
flight resulting in injury.
Then Harold (Hal) Graham took over pilot duties and after initial training on
a tether he performed the first successful free flight on 20 April 1961 near the
Niagara Falls Municipal Airport. After a few more test flights the first public
demonstration was on 8 June 1961 at Fort Eustis, Virginia. On 15 June two flights
were performed on the lawn of the Pentagon then on 13 October Hal performed a
demonstration flight for President Kennedy at Fort Bragg.
Other rocket belt pilots were Bob Courtier, Peter Kedseriski and Bill Suitor.
The Bell Rocket Belt is powered by a hydrogen peroxide reaction rocket engine
which consists of a tank of compressed liquid nitrogen which pushes hydrogen peroxide
out of two other tanks into a reaction chamber. There a chemical reaction creates
an extremely hot high pressure stream that escapes from the flight nozzles and
propels the unit and pilot.
The
sound of the rocket is said to be incredibly loud, almost unbearable, and more
a scream than something more identifiably a rocket noise. Two hand controls control
the pack with considerable accuracy which leads experienced pilots to insist that
it flies like a dream.
Although the U.S. military displayed some early interest in the rocket belt concept
during the 1960s, the short flight durations and exposure to enemy fire made the
belts unappealing as combat tools.
Apart from the Bell Rocket Belt, another rocket pack was designed by Brad Barker
and Doug Malewicki. This is the RB2000. It is essentially similar to the Bell
model but is able to fly 30 seconds, against the Bell's 20 seconds.
The
fourth rocket man, Bill Suitor, starred in some films and television. The device
made its big-screen debut in the pre-title sequence which traditionally begins
James Bond films, in the movie "Thunderball" (pictured right).
The U.S. government built and flew at least one true jet pack during the sixties.
It was powered by a small turbine built by Williams Research and had an endurance
of approximately 30 minutes. It was abandoned since it was less cost-effective
than a helicopter, and required any passenger to be a skilled operator.
Nonetheless, various civilian groups have continued to pursue the concept. Personal
packs have the advantage of being able to maneuver in small areas and of getting
closer to vertical surfaces than the blades of a helicopter allow. This ability
suggests roles in search and rescue, media work, policing and crowd surveillance
and control.
