[122] Although not as fast as the Spitfire, the Zero could out-turn the Spitfire, could sustain a climb at a very steep angle, and could stay in the air for three times as long. [123] To counter the Zero, Spitfire pilots adopted a "slash and run" policy and used their faster speed and diving superiority to fight, while avoiding turning ...
If "bounced" while cruising at low speeds it could take a Spitfire up to two minutes to accelerate to top speed. [58] The only way it was thought that a Spitfire could evade attack was to cruise at high speed and go into a shallow dive with the throttle open. Provided the Fw 190 was seen in time, it could be forced into a long stern chase. [57]
Fire from the eight machine guns of a Hawker Hurricane is shown converging to a point, then diverging. (Drawing not to scale.) In aerial gunnery, gun harmonisation, convergence pattern, convergence zone, convergence point or bore-sight point refers to the aiming of fixed guns or cannon carried in the wings of a fighter aircraft.
These rifles are similar to the L115A3 Long Range Rifle used by Craig Harrison but outfitted with Schmidt & Bender 3-12x50 PM II telescopic sights. Reports regarding the longest recorded sniper kills that contain information regarding the shooting distance and the identity of the sniper have been presented to the general public since 1967.
Depending on the supercharger fitted, engines were rated as low altitude (e.g.; Merlin 66, Griffon III), where the engine produced its maximum power below about 10,000 feet (3,000 m), medium altitude (Merlin 45), where the engine produced its maximum power up to about 20,000 feet (6,100 m), and high altitude (Merlin 70), where the engine produced its maximum power above about 25,000 feet ...
For rifles, ease-of-use features such as the design of the bolt or magazine release can affect the rate of fire. For artillery pieces, a gun on a towed mount can usually achieve a higher rate of fire than the same weapon mounted within the cramped confines of a tank or self-propelled gun. This is because the crew operating in the open can move ...
The .22 Spitfire is an American wildcat rifle cartridge developed by Col. Melvin M. Johnson. It was originally named the MMJ 5.7mm [ 1 ] by its designer and is also known in the U.S. as the 5.7mm Johnson , the Johnson MMJ 5.7mm Spitfire , and the .22 Johnson , (or 5.7×33mm internationally).
According to Newtonian mechanics, if the gun and shooter are at rest initially, the force on the bullet will be equal to that on the gun-shooter. This is due to Newton's third law of motion (For every action, there is an equal and opposite reaction). Consider a system where the gun and shooter have a combined mass m g and the bullet has a mass m b.
