The Proton M's improvements included lower stage modifications to reduce structural mass, increase thrust, and fully use propellants. Generally a Briz-M ( Russian : Бриз meaning Breeze ) storable propellant upper stage is used instead of the Blok D or Blok DM stage, removing the need for multiple fuel supplies and oxygen top-off due to ...
A particle-beam weapon uses a high-energy beam of atomic or subatomic particles to damage the target by disrupting its atomic and/or molecular structure. A particle-beam weapon is a type of space-based directed-energy weapon, which directs focused energy toward a target using atomic scale particles.
The poorly ignited charge moved the projectile partially down the tube, increasing the surface area of the propellant. The increased surface area of the propellant then ignited in the tube, raising pressures in parts of the gun not designed for them. The large overpressure caused "catastrophic tube failure" (an explosion destroying the gun tube ...
This was the 326th launch of a Proton, the 16th Proton-M/Briz-M launch, and the 41st Proton launch to be conducted by ILS. [13] It features more efficient first stage engines, updated avionics, lighter fuel tanks and more powerful vernier engines on the Briz-M upper stage, and mass reduction throughout the rocket, including thinner fuel tank ...
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
A combustion light-gas gun (CLGG) is a projectile weapon that utilizes the explosive force of low molecular-weight combustible gases, such as hydrogen mixed with oxygen, as propellant. When the gases are ignited, they burn, expand and propel the projectile out of the barrel with higher efficiency relative to solid propellant and have achieved ...
Project HARP originated as the brainchild of Gerald Bull, a renowned but controversial ballistic engineer specializing in high-velocity guns and gun propulsion systems. [2] [3] In the mid-1950s, Bull was working on anti-ballistic missile (ABM) and intercontinental ballistic missile (ICBM) research at the Canadian Armaments and Research Development Establishment (CARDE) when he formulated the ...
The oldest gun propellant was black powder, a low explosive made from a mixture of sulfur, charcoal, and potassium nitrate. It was invented in China during the 9th century as one of Four Great Inventions , and still remains in occasional use as a solid propellant for antique firearms .
