I wonder if Ed Brown is anyway related or formally associaited with a Brown Manufacturing that was the motor manufacturer for Model Missiles,Inc before G.Harry turned to Vern and Estes Industries....?
I do know one thing: Ed Brown probably knows more about the design and manufacture of BP rocket motors than anybody alive perhaps....I have a technical article written by some russians that Mr. Brown reviewed for completeness and accuracy....It was on the design and shape of the combustion cavities in BP motors.....amazing how cylindrical and or conical combustion chambers of various lengths/widths can determine whether a motor is low/med/hi thrust.. It surely opened my eyes.....I once asked Mary Roberts if she could provide me with the diameters and lengths of the various combustion cavities on the various estes model rocket motors and of course she declined, as this was estes proprietary information....
