Serious question, anyone know the ballpark figures of thrust-to-weight based on 1000 ft/min ascent rate for fully loaded and ground level?
I'm trying to calculate maximum theoretical fuel capacity, essentially 1:1 thrust-to-weight, given it burns kerosene - 6.82 lbs/gallon at STP.
10 gallons of kerosene = 68.2 lbs is much less than the weight variation of a standard adult human, which falls roughly in the range 100 lbs - 200 lbs, so doubling the fuel capacity should be easy.
I suppose engine upgrades would also be easy. They did mention the JB-10 was in the works...
[Edit: thanks Retric, 68.2 lbs not 16 lbs]
- Retric 11y ago10 gallons of kerosene = 68.2 LBS
- jessriedel 11y agoYea, 10 minutes of flight time seem incredibly high to me. That means you could significantly increase it with external fuel tanks (say, for a total of 20 gallons). 15 minutes would be a darn long jet pack ride. Limiting factor is actually just how much weight you could plausibly carry on your back. (Edited numbers.)
- trhway 11y agoit seems they are using pure jets and in this case high-by-pass would be a way to immediately improve the thrust and thus to decrease the fuel consumption.
- watmough 11y agoIt crossed my mind that all you really need is the right engines and some means of control ... http://jetbeetle.com/JB_body_products.htm http://jetbeetle.com/JB_body_products.htm Cost for 150lbf thrust about $15k http://crxturbines.com/jetbeetle.htm http://crxturbines.com/jetbeetle.htm
