BONNEY LAKE, Washington USA — Blastzone.com is pleased to announce the public release of BurnSim, a new Motor Design and Simulation Software.

BurnSim is solid propellant rocket motor performance prediction software. In a nutshell, input your motor design and propellant characteristics and BurnSim calculates the Kn through the burn and predicts estimated chamber pressure and motor performance. Once your motor design is in BurnSim, you can tweak the parameters such as nozzle diameter or grain core diameter and instantly see how the Kn, chamber pressure, and motor thrust is effected. If you wish, you can specify a desired maximum Kn, and BurnSim will find the right nozzle throat diameter to produce the desired results.

Once you're happy with the your motor design, BurnSim can then export a .ENG file for use in Rocksim, wRasp or other rocket flight simulators. You can estimate your motor's performance and rocket's flight before you even cast a grain!

Features:

• Supports BATES grains with 0-2 restricted ends, end burning grains, and D Grains. Any number in any combination.
• Instantly see a graph of Kn, chamber pressure, thrust, and see how it changes when you change motor attributes.
• Save your motor designs and propellant characteristics
• Export predicted motor performance into .eng files for use in Rocksim or wRasp

BurnSim can be downloaded and evaluated for 7 days at no cost.  A lifetime license for BurnSim (single user, any number of machines, no cost for future upgrades) is currently only $25.
