The MK 90 propellant grain
is the propulsion component of the Hydra 70 family of rockets used by the US military and several allied nations to support overseas operations.
M2 EQUITYBITES-August 21, 2015-BAE Systems gets USD50m munitions contract for MK 90 propellant grain
Regardless of the composition, however, all propellants are processed into a similar basic geometric form, referred to as a propellant grain
The oxidiser is generally a crystalline solid (such as Ammonium Perchlorate), the fuel and oxidiser are premixed into a propellant grain
which is contained in a motor case.
Under the contract, Positron Systems will demonstrate that its Photon Induced Positron Annihilation (PIPA) technology can detect structural and chemical reaction issues in solid rocket motor propellants, prior to the onset of propellant grain
There are also effects expected in the area of propellant grain
regression rate that plays a primary role in the performance of hybrid propulsion for instance.
Tenders are invited for Extruded Double Base Propellant Grains
When you compress a heavy charge of "stick" powder, you can actually hear the crunch of the propellant grains
breaking up under the bullet base.
After this cooking phase is done, the propellant grains
are dried in temperature- and humidity-controlled cabinets to very exacting amounts of residual moisture.
It could outrange Iraq's Soviet-made tanks because energetics experts developed high-energy propellant grains
, each the same size and including engineered holes that enabled increased combustion.
By exposing the insects to the odor of explosives followed by a sugar water reward, researchers said they trained bees to recognize substances ranging from dynamite and C-4 plastic explosives to the Howitzer propellant grains
used in improvised explosive devices in Iraq.
