Abstract : A mathematical analysis of the effect of flight conditions on ramjet cousion chber mensions s presented. The analyss is based on the reltionships between the pressre, temperature, mixre composiion, urbulence, and pincipl comstion chracteristics. The relationships were studied principlly for the costion of a homogeneous mixture in a turbulent flow, in which the evapotion of fuel droplets and the mixing of its vapor with the r are fully completed at the instant of combstion start.A-255 371N! !+ %+%, %!>%, >>*, !), >>$), !>+(, )+, !)<, ><>!, <*!>, >%$!, <%$, <<+> d-255 372Div. 22 (15 May 61) OTS price 48.10Abedeen Proving GROUND, MD.

Tets were conucted to estabish charge weights for charge, dual-granuation, XM51E!, FOR THE !%%-M HOWIZER, T258. The M17 propellant tested consisted of a single-perforated propelant for the base charge and a multiperfoted propelant for chrges 2 through 6. In the early phases of the test, the single-perforated propellant proced very eraic chber pressures when fired with the zone 6 charge. o eablish a sasftory propelling charge, lot PA-E-31526 was replaced with a previoly teted, muliperforated, M17 propellant. Using the multiperforated propelant 9web 0.09 inch) in zone 1, and 0.0576-inch-web propellant in zones 2 through 6, a satsfactory charge estashment was completed at nomal and extreme temperatures. he ingle-perfoted propeant ws considered isfatory for use only s a zone 1 charge.
