Static Test Data Files
Class-Measured Thrust Curves
The tables below contains the experimental thrust curves from the motor static-test labs. Videos of some of the tests are available here. The data files are in tab-delimited text format, with header information about when the data were taken, the average thrust, and the total impulse. The entries in the table correspond to when the data were taken (month/day/year) plus which motor when the same designation of motor was tested more than once on a given day. The first table contains the data in newtons and the second in pounds-force.
Data – Class Thrust Curves
There are a series of LabVIEW VIs that can be used to read and/or display the thrust curves. They are
- ReadThrustCurve.vi will read a thrust-curve file and create LabVIEW arrays with the information. It is required by the other VIs.
- Get Thrust Array.vi takes an input of an array of strictly-increasing time values and returns an array of the thrust values from a given thrust curve at the times.
- SampleThrustCurve.vi takes a desired sample rate as an input and returns an array of time values starting at 0 and spaced at the sample rate, and an array of thrust values at those times.
- 1DsimNoDragOrWind.vi is a 1-D explicit Euler simulation of a rocket in the Earth's gravitational field being powered by a chosen motor, and experiencing no drag or forces other than thrust and gravity. It terminates at the earlier of the chosen end time or when the rocket returns to an altitude of 0. It requires both ReadThrustCurve.vi and SampleThrustCurve.vi.
