New Motor Certified, May 2023

[Alan Whitmore]

The Tripoli Motor Testing Committee met today and certified the new Aerotech H14 ST motor. This is a single-use, 29mm, endburner with a total impulse of 240.12 N.s, an average thrust of 13.21 N, and a burn time of 18.255 seconds (!).

Very nice; thanks for that graph with the multiple curves. (Again we see a variation in max. thrust.)

I was told that for the motor to work out great the rocket needs to be about 10oz.

Glad I haven't invested in a "flying H13" project yet.

Glad I haven't invested in a "flying H13" project yet.

H13 still has a place, as it can be flown without a waiver in just about any rocket light enough to fly on it safely. H14 has too much propellant for a Class 1 rocket.

Too bad i just bought 2 H13's.... I got them for the sustainer of a staged 38mm to 29mm min dia project. These endburners are perfect for high thrust boosters to long burn sustainer rockets.
