TMT has tested and certified three new Aerotech High Power motors. First is the 38mm DMS I40N-P, a Warp Nine endburner in the same mode as the G8 and H13: A start-up spike, and then a long sustain.
The second is the first Aerospike nozzle motor that we have tested. It is called the J615ST-20A, and is a reload kit made for the 54/852 hardware. The customer needs to be aware that the thin ring that constitutes the "nozzle" of this motor is narrow enough that the ignitor must be installed before the rear closure is screwed on. This must take place at a safe spot designated by the RSO.
The third new motor is a single-use 4" DMS motor called the N1975W-PS. Thrust curves are (I hope) attached below.
