Gasping for Fumes

Finally we take a look at which propellant we should use for our rocket motor here. As mentioned in earlier posts, the two prime candidates for near future warship propulsion are the combustion rocket, and solid core Nuclear Thermal Rocket (NTR). 1,701 more words

Four wild technologies lawmakers want NASA to pursue

(Source: arstechnica.com)

Imagine a tissue-box sized device, with blades a few feet long, whirring to life after charging for a full Sol on Mars. It then flies ahead of a rover to search for hazards and targets of interest. 1,327 more words


Slosh Baffles

So much time is spent discussing rocket engines that one of the most important parts of a rocket is glossed over: the propellant tanks. A significant amount of engineering goes into them, despite their simple appearance. 1,675 more words

HM-7 Test Fire 3

Cal Poly Space Systems conducted a successful full duration test fire of Hybrid Motor 7. The oxidizer pressure was too low, leading to decreased thrust at the end of the burn. 27 more words

Cutless Bearing

Here is the link on the A30 site to the information on the baring that we all seem to have.

The Cutless Bearing is 1 3/8″ O.D. 29 more words


Rocket Propulsion, Part 2

See Part 1, where I introduced the problem. Constant acceleration of an object (such as a spacecraft) produces a linearly increasing velocity and therefore a quadratically increasing kinetic energy (since… 1,524 more words


Rocket Propulsion, Part 1

The kinetic energy of an object (the energy it has due to its motion) is equal to ½mv2; that is, half the product of its mass and the square of its velocity. 1,253 more words
