ThrustCurve Background

This site debuted in 1998 as a repository for simulator files generated from actual motor firing data provided by Tripoli Motor Testing. At that time, the goal was to provide accurate simulator files converted directly from the data obtained at the motor test stand. I was able to get data for most TRA-certified motors, but NAR was never willing to make any data available.

Subsequently, TRA stopped making data available and the site languished. There was still the original set of generated files, but it quickly became outdated as new motors were introduced and new motor manufactuers entered the market. As an stop-gap measure, I added a page to which people could contribute data from other sources (usually from the motor manufacturer).

I had thought repeatedly about changing the format of the site to being organized around the entire set of certified motors from all three organizations. (CAR entered the certification business during that time as well.) Good intentions finally turned into action in 2006 when I started working on the site you see now.

The new model turns the old site inside out. Instead of being driven by motors for which I have data, the list of motors is taken from the NAR-maintained master motor list. (See the comprehensive list on the NAR site.) Additional information is pulled from the web sites of the three certification organizations to fill in the details.

With the master motor list set up, motor data files can be contributed by anyone who has them. The data is no longer as "authoritative," but at least whatever is floating around can be available in one place. Please help out the effort by contributing data files if you have any that are missing here.

In 2009, Mark Koelsch, who had been a major contributor of motor data, joined as editor of motor information.

I hope you enjoy this site and find the information and data useful,
