parametersfor hydra-jet fracturing. Only the nozzle diameter, nozzle number,and nozzle pressure drop are determined; other relevant parameters such as flow rate and surface pressure can be calculated. Based on the experimental and theoretical researches, the nozzle pressure drop is expressed as (Shen...
Since nozzle contours closely approximating the MOC-based contours are highly efficient, the major decrements in ERE are due to incomplete propellant vaporization and mixture ratio distortion, i.e., Cstar efficiency effects. Beyond using an internal contour which efficiently produces thrust, the most...
A magnetic field directs the charged plasma to the smaller rear nozzle or cone of the engine creating a remarkable thrust never before harnessed by humans. With this level of propulsion spacecraft would be able to achieve speeds 10-times faster than current rocket engines. This gets us to ...
You know, Ben talks about family perhaps a little bit concerned that he would set the barn on fire. I was playing with little matchstick rockets as little wooden matchsticks you wrap in aluminum foil, you put it on a paperclip saying to heat it up. If you get the nozzle right, you ...

A poster from the movie “Fire in the Sky” based very loosely on the Travis Walton incident. The Travis Walton Abduction by Emma On November 5th, 1975, a lumber jack from Arizona named Travis Walton allegedly went missing while at work in the Apache-Sitgreaves National Forest near Snowflake...
A Nuclear Thermal Rocket (NTR) next to a Magnetoplasmadynamic (MPD) Thruster at the bottom of the image. The NTR is roughly 60 times as long, and masses 6000 times as much. Much of that difference is in the NTR’s enormous nozzle. ...
