CONT

... the gun barrels are fitted with muzzle velocity sensors, which are linked to the fire control computer, so the actual speed of the round can be taken into account when the computer calculates the lead angle necessary to hit a moving target. This is necessary as the speed of the round when leaving the barrel may vary depending on the ammunition manufacture date and age, moisture content, the barrel wear, etc.

CONT

Projectile muzzle velocity sensor mounted on T-84 MBT [main battle tank] turret roof. As an option, the tank fire-control system can also include a projectile muzzle velocity sensor, which measures the velocity in question and feeds information to the tank’s fire control ballistic computer after each firing of the gun to allow to automatically correct for gun bore wear, charge temperature and other factors.

CONT

The pulsed plasma thruster(PPT) with solid propellant is used for low power propulsion systems; typically with an average power less than thirty watts. Capacitor stored electrical energy is used to create a pulsed arc discharge across the face of a block of propellant, teflon in most implementations to date. The combination of thermal flux, particle bombardment and surface reactions ablates and ionises a small amount of the solid material... The peak discharge current is high, in the region of tens of kA. The self-induced magnetic field acts on the ions moving in the electric field creating the discharge to create a Lorentz body force that accelerates the plasma. Teflon PPTs have enjoyed limited use in east-west station keeping and sun pointing applications. PPTs do not produce sufficient thrust to be considered as candidates to provide primary propulsion of future out of Earth orbit missions and were not considered for SMART-1.

This letter is set up in the full-blocked style, in which every line begins at the left margin. A few companies modify it by moving the date to the right, but most firms use it as shown here.

  • Techniques d'écriture
CONT

Lettre à un seul alignement. La disposition à un alignement rend la lettre facile et rapide à écrire, mais est peu élégante et peu pratique dans le cas d'imprimés, car la marge gauche est alors surchargée.
