HE BI LEVEL ROCKET PROPULSION DESIGNED
|Consideration of the Diesel Engine precluded carrying heavyweight fuel into space|
But other forms of rocket propulsion are more damaging to man and the environment such as atomic and nuclear engine drives that have risk of explosion and releasing radioactivity and contaminating the Earth for many years or decades.
Of course, rocket propulsion must be cost effective and simple to supplement bringing space tourism to a safe and affordable level. Space1 is working on a Hybrid Engine that incorporates the best of a couple technologies, spinning old and new together. A new rocket engine design is introduced in November of 1015, named the HE.
There's two levels of space, the first level requires moving through the first level of Earth's space known as the Troposphere, and the second level moves beyond the Earth's space into the Solar System and the first realm of Deep Space. The HE design incorporates this bi level propulsion. The two worlds of engine design utilize a common propulsion for level I and electrical for level II.
Also examined and studied are propulsion using hydrogen, oxygen, diesel, kerosene, and nitrogen. These may be more range and velocity sensitive.
