Above this speed, given sufficient initial flight velocity, a ramjet will be self-sustaining.
2.
Although of lower muzzle velocity than the 12 C50 gun the 13.5 C45 weapon s heavier shell maintained its in-flight velocity to a greater range and so had greater hitting and penetrative power.
3.
The applied voltage and the pH-value of the electrolyte ( amount of ions it contains ) also vary the balance between thrust, efficiency and maximal exhaust velocity ( determines the maximal achievable flight velocity ).
4.
Given the overwhelming Allied air superiority, the " Luftwaffe " put its effort into the development of aircraft of such high performance that they could operate with impunity, but which also made bomber attack much more difficult, merely from the flight velocities they achieved.
5.
Then from 1992 to 1998 an additional 6 flight tests of the axisymmetric high-speed scramjet-demonstrator were conducted by CIAM together with France and then with NASA, USA . Maximum flight velocity greater than Mach 6.4 was achieved and Scramjet operation during 77 seconds was demonstrated.
6.
It does this by effectively taking the . 50 BMG projectile, which already is relatively large and travels extremely fast, and effectively increases the already supersonic bullet to over 1.3 times its normal flight velocity, creating more kinetic energy without the need for a larger and heavier projectile.
7.
It Does this by effectively taking the . 50 BMG projectile, which already is relatively large and travels extremely fast, and effectively increases the already supersonic bullet to over 1.8 times its normal flight velocity, creating more kinetic energy without the need for a larger and heavier projectile.
8.
Specific thrust has significant bearing on thrust lapse rate : the low jet velocity associated with a low specific thrust engine implies that there are large reductions in net thrust with increasing flight velocity, which can only be partially offset by throttle changes at rated conditions ( e . g . maximum recommended climb rating ).
9.
With in-line tandem seating, the trainer was developed in accordance with the Federal Aviation Regulations ( Joint Aviation Requirements ) 23 regulations for acrobatic category of airplanes and it provides an easy transition to Kobac and then to Hartzell HC-C2YR-4CF / FC 8475-6, which provides maximum flight velocity ( at an altitude of 3000m and a takeoff weight of 1085 kg ) of 345 km / h.
10.
Although just 1.5 inches larger than the earlier 12-inch gun it fired a shell weighing against the of the earlier gun, although of lower velocity than the 12 C50 gun the 13.5 C45 weapon s heavier shell maintained it s in-flight velocity and so had greater hitting and penetrative power, the new gun was also very accurate and possessed very good wear rates up to 450 rounds per gun, tests also showed that the gun had a very good safety margin so that the following " King George V "-class ships could fire an even heavier 1, 410 lb shell, although this lowered the wear rate to 220 rounds per gun.
