I found out that I’ve completly missed out a lot of posts on work that was done on the SV-302 vehicle internal simulation. Instead of making the progress posts, I will post descriptions of the SV-302 systems done so far, but maybe a bit later. I don’t really feel like wording it all right now.
So this post will be just a general overview, something I can later link people to when they ask me “wats sv302″.
SV-302 is a project of writing an internal systems simulation for a single-stage-to-orbit spaceplane – a vehicle that doesn’t require additional boosters or fuel tanks to reach orbit. The aerodynamics are based off the real X-30D project – for the sake of simplicity (and if you want to find out the real reason, scroll back into old posts, and you will find that I really suck at developing waveriders).
It has three types of engines: high-perfomance turbofan engines, which speed up the vehicle to speed of 5 mach (the increased speed is possible due to active internal cooling), switching over to variable geometry scramjet engines, which speed the vehicle up to about 17 mach. After reaching this speed, the vehicle switches over to a linear aerospike rocket engine, and reaches the orbital velocity.
The project concerns detailed physics simulation of all primary systems (for example electric system simulation calculates all voltages and currents flowing through main electric buses, and all the loads that devices are acting on the system).
At the moment of writing this post, I’ve been working for two months rewriting the simulation, and I’ve got electric system, computer systems (and related sensor systems and MDM systems) simulations, power reactant distribution simulation, basic software for the on-board computer system, lots of misc systems (like caution/warning system), and temporary simulations for RCS, GPS, etc.
