Patented July 2, 1940 UNITED STATES PATENT OFFICE PROPELLANT CHARGE Ernest R. Rechel and Thomas Stevenson, Philadelphia, Pa.
No Drawing. Application January l'i, 1940,
Serial No. 314,266
1 Claim. (CL 52-13) (Granted under the act of March amended April 30, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to us of any royalty thereon.
5 This invention relates to a propellant charge.
It is well known that double base powders have a higher potential than single base powders and r with a given volume of charge, other conditions remaining the same, they are capable of giving higher velocities.
A serious disadvantage with double base powders is the fact that at sub-zero temperatures they yield higher pressures than at normal temperatures. Occasionally these pressures become high I5 enough to burst the gun. Although very little is red phosphorus type of non-corrosive and nonexplosive primer is different from other vprimers inthat it gives a reduced pressure with double base powders at sub-zero temperatures and thereby eliminates the danger of bursting the 5 gun.
As an example of this type of primer the following mixture gives excellent results:
Per cent 10 Red phosphorus 5 to Barium nitrate to Antimony fid 10 to 25 This type of primer is more fully described in copending application of Pritham, Ra hel and 15 Stevenson, Serial No. 194,384 filed March '7, 1938, Patent Number 2,194,480 patented March 26, 1940.
We claim:
A propellant charge comprising a double base powder wherein nitroglycerin is one of the base constituents and a. non-corrosive and non-explosive primer including red phosphorus.
