This shows a mid-burn image of an 18-inch 38mm hybrid motor static test. This shows a mid-burn image of a 30-inch 38mm hybrid motor test.

This shows a startup transient in an 18-inch motor test, that caused the blast deflector to be utterly obliterated. The flying debris that you see is a mixture of ignitor material, and molten concrete!! This shows the launch of a BSR Optimal 65 on the 18-inch motor. The flight carried a BSR altimeter, providing two-stage recovery. The rocket was recovered about 1000ft downrange, with an altitude of 1700ft given by the altimeter. Even though the road looks awfully close to the rocket, in fact it's several hundred feet away. This effect is due to the processing and optics of the DV camera that was used to take this shot.

This shows the same rocket, a fraction of a second later, leaving the pad. Note the near complete lack of smoke, characteristic of hybrid rocket motors. A very rough thrust curve from a single test-flight of the 18-inch motor, with an underoptimal (too large) nozzle. Since the data are accelerometer derived, they're not very reliable.
