My German Empire

In World War II, the bombing method is not a few kinds of ways.

The big name is bombed, and the plane is pushing down on the steep angle, and is generally more than 45 degrees with the ground angle, or even vertical. Bulling to the place where the target is very close, pulling up quickly.

However, the dive bombing is high for the aircraft performance, because the aircraft is very strong during the dive process, so the body structure is to be strengthened, and the aerodynamic design is also different, and it is necessary to dive the deceleration plate, resulting in aircraft speed and performance. In addition, once the bomber starts to dive a move, it is easy to change the direction, this is easy to bite by the enemy fighter and shot down.

There is also a sliding bomb. This bombing is usually used by combat bombs, attackers, or fighters. The aircraft is inserted into the small angle, and the fly projection is flying when the target is close to the target, and then pull up quickly. The Soviet "Ir-2" attack machine often bombed it.

This kind of bombing is not high, the bomb can not be large, but the aircraft intensity is not high, saving fuel, is suitable for bombing the target bombing.

There is also the most common horizontal bombing.

Since the flying height of the bomber is usually high, the bomb is not straight up from the plane, but a parabolic. So calculate the bombing advance angle to make the bomb accurately hit the target. Here is a lot of parameters such as airborne speed, ground speed, bias angle, wind speed, flying height, and bomb average velocity.

No reliable means can throw a bomb very accurate.

However, the US military does not seem to believe in evil. Their strategic bombing thoughts emphasize the high-precision level strategic bombing, that is, a particularly bombing of an enemy's specific industry or goal to weaken the power of enemy. For example, in the World War II, the US military focused on the destruction of the German fuel industry and the manufacturing industry, and its effect can be described as immediate.

Of course, in terms of technical requirements, high-precision bombing requires a high-aspiratory bomber, the US military, I need a very important thing - bomber sight. Advanced sights ensures that the bomber is high-precision bullets at maximizing the impact of the enemy's high-tech gun, which can avoid losses and ensure accurate bombing of the target.

In this regard, the United States spent 1.5 billion knives to develop bomber sights - Norton aimer! This is a huge overhead at the time. The Manhattan program in that year, the Manhattan plan has grown to approximately 3 billion US knives, which means that Manhattan planned overhead can only develop two similar Norton aimer project, thereby visible to the importance of this equipment!

This Norton bomber sight developed by C.L Norton is generally divided into two parts, namely stabilizers and sights.

The stabilizer is a work platform that uses the anti-screw holding level to provide a stable work platform for aiming. The automatic driver of the stabilizer and bomber allows the sight to calibrate the stabilizer to ensure the direction of the aiming set and the aircraft flight direction.

The most important sight part is the main working system of the entire Norton bombing sight. It consists of three parts, that is, the mechanical simulation computer for calculating the population, a small telescope and a system consisting of a motor and gyroscope.

The use of Norton bombing aiming is not very complicated. When the aircraft is close to the target area, the bombing aiming hand needs to use the telephoto eyepiece to find the goal, this process can be done with a set of mirrors. After finding the target, the bombing aims can put the target in the horizon, then open the power switch of the Norton bombing sight. Once the switch opens, the telephilic server will ensure that the eyepiece is always aligned with the selected target. Since the speed of rotation of the service agency depends on the distance of the target and the approach of the aircraft, this requires the transfer hand to set the aircraft in the Norton bombing sight on the Norton bombing sight in the Norton bombing sight in the Norton bombing sight.

After the Norton bombing is set,

Of course, this is just theory, can't do it in actual combat.

Norton At the time, the theoretical calculation was assumed that the aircraft was bombed at a low-altitude, but B17 and other bombers were in high altitude, and the Norton sight was poor. Moreover, the bombing hand must be visible to the goal, and the cloudless weather is impossible, which also limits the ability of the Norton sight.

There is a very famous example. In 1944, the Allies bombed the Chemical Plant in Royner, and the factory covers an area of ​​757 hectares. In the 22-round bombing mission, the aircraft equipped Norton aimer and cast 85,000 bombs. However, only 10% of the bombs have fallen into this 757 hectares of chemical plants, while these 10% of the bombs have a dumb bomb. After many violent attacks, the factory started in a few weeks.

Even so, "Norton" is technically outstanding, so the US military will consider "Norton" bombing sight as the highest secret, and set a series of confidential provisions, such as "Norton" aiming must be covered with canvas, only Can be installed on the bomber before the take-off, after landing, it must be removed immediately, and the disassembly process must be carried out under the supervision of the armed guards. The crew of the bomber must swear to guard the aim of the sight, and capture the capture of the aircraft. The "Norton" aiming, etc.

Funny is in such a rigorous security measures, Germany has got a complete design drawing. Because Norton has a bunch of German engineers, one of the engineers called Herman. Dragon, pay the entire drawings to Germany.

Although Germany also has Norton aimer, it is not so easy to use with the United States. In addition, the German Air Force did not have a group of strategies in groups ... so they didn't use it.

Nowadays, Germany has developed a navigation / bombing radar of 3 cm wavelengths. Relying on this bombing radar, the bomber can also get the same bombing as sunny during the night or thick clouds. The night and clouds can also protect the bomber, avoid the enemy fighter to intercept and threaten the fire.
