The basis for all the rocketry and wind tunnel posts discussed previously are primarily for the development of a micro-ramjet engine. For now I have gone as far as I can on the supersonic wind tunnel and the design has more or less been finalised, all the tunnel wall contours for the test sections are... Continue Reading →
Now for something completely different…
So the reason I've been messing around with rocket motor design lately is that an old idea I started dabbling in several years ago, that of a truly miniature ramjet, something that could fit in the palm of your hand. I have read a report on a tiny ramjet designed to operate at Mach 4, however I'm... Continue Reading →
Solid Fuel Regression Part 2..
So in this second of my posts on solid fuel grain regression I'll cover more complex grain core shapes, although the process is not overly dissimilar to the methods discussed previously. An average web length is found and an incremental distance is then defined, this distance is then used to regress each point of the... Continue Reading →
Solid Fuel Regression Part 1
In the first of a series on the modelling of rocket motors I'm going to cover the aspects of the design of the solid propellent grain, which is the hardened mass of combustible propellent within the motor itself. Solid fuel rocket motors range from the model rocket motors produced by the likes of Estes with their... Continue Reading →
