What Is A Jetpack?



There is some confusion over what a jetpack is/ was/should be.



Basically it comes down to a disconnect between what is science, what is engineering and what is �common usage�. Many engineers, particularly in the aviation industry, make distinctions.



A gas turbine powered� prop is not a jet but uses gas turbine calculations.



Whereas a gas turbine powered fan (turbo fan) they call a �jet� in actuality it could more correctly be called a �gas turbine powered ducted fan�. To most people a device that you strap on your back which burns fuel, makes noise and you fly around in, is a �jetpack�. The majority of people call the Bell Rocket Belt a �jetpack�.



Actually it is not what an engineer would call a jet, it is a rocket. However, by the science definition, the coherent stream of steam coming out of the nozzles is a �jet of steam�.



So why call our device a �Jetpack�?



Well, by both common usage and science it is a jet. We already have jet ski and jet boat. I do not believe that an aviation engineer will be able to convince all those owners to start calling their devices a �water pump propelled boats�.



In the end we found that 95% plus of people call it a jetpack when they see it, so why fight that ?



If you have a very narrow view of what a �true jetpack� is (i.e. that it is a pure jet) then none have ever been built. The closest would have been the Bell jet belt, but again this was not a �true jet�, it was bypass ratio gas turbine powered. In fact I cannot think of any �true jets� in the GA industry, most are Fanjets.



Perhaps now you see that the �correct answer� is far more complicated and debatable, so much so that normally it is not worth even starting the discussion, because the �correct� answer relates to opinion not fact.
