Motor Specifications and the Nozzle

This is an N2837 motor, with a total impulse of 16.5 kNs.

...

Lastly, the expansion ratio for our booster is 7.65.

The nozzle has a throat diameter of 1.085 in and an exit diameter of 3.0 in. The throat length is 0.1 in.

The divergence and convergence half angles are 15.0 and 60.0 degrees, respectively. A close-up 3-d drawing of the nozzle can be found below.
