What Is a Rotary Shear?

Scissor flight is a series of reverse rotations when the fighter turns to the opponent, the purpose is to seize the attack position behind the tail. In an air battle, if the attacker notices that the target is about to fly over, and the defender turns to the attacker prematurely after discovering this situation, then both sides enter scissor flight. If you are an attacker, scissors flying should be the last thing you think of, and as a defender, scissors flying means that you will be in danger, and it also means that the attacker has made a mistake.

Scissor flight

(A series of reverse rotations when the fighter turns to the opponent)

No matter which pilot you ask, he will tell you the same thing: "If you enter scissor flight, you will be in danger."

Both the offensive and defensive sides constantly delay their time on the forward path by repeatedly rotating the disk, and at the same time, they want to obtain a good trailing angle.

So the actions of the two sides intersect to form a scissors maneuver.

This situation arises because both sides are unwilling to compromise, and the performance of the circling deadly, through each disc rotation to turn as far as possible ahead of the opponent, accumulating advantages until one side is half a beat slower than the other, so the latter hemisphere advantage Appeared. But such a high overload confrontation process consumes too much energy, the speed of both sides will not only decrease, the height will continue to decrease ... until one side gets rid of, separates, accelerates again, and then continues to fight ...

When flying in scissor mode, it is not used for anything other than maintaining high G and turning to enemy aircraft. Of course, this will quickly consume speed and energy. In theory, in the scissor flight, the [victor] represents forcing the enemy aircraft to be in front of itself and having enough energy to direct the nose to the enemy aircraft. More commonly, one of the fighters stalled and crashed to the surface. If the other fighter still left any kind of energy, it should make a turn and descend and attack the enemy before the enemy recovered. Another situation is that the two parties in the war can replace a sharp turn with a series of barrel rolls and maintain some energy by the altitude / speed conversion, but this is not the ideal answer.

Whenever fighter planes meet, the two sides run the risk of collision and fire. Intersecting too far apart will allow you to enter the cannon firing, while too close results usually result in collisions. In short, scissor flying is bad.

If you find yourself in a scissor flight, how do you get out of it? In an environment where only guns are used, S can be executed immediately when the tail of the enemy aircraft is skipped. If you can continue to increase and maintain speed, you will be able to escape the enemy gun's gun range. In the environment where the enemy aircraft uses the missile, breaking the S will make the hot-seeking missile lock the tail nozzle of your engine. If you can't escape the enemy's weapon range, you have to win scissor flight. If you can't win scissor flight with the help of outside turns, you are dead.

When climbing, rolling and scissors are combined, the pilots have another way of confrontation-Vertical Rolling Scissors, ascending and rolling scissors, commonly known as "rising shears".

This is actually talking about the combination of the three. It seems complicated, but it is simple. The two sides confront each other during the climb and make each other roll the scissors to bite the tail. There is no obvious defensive or offensive point. If the defensive side has good climbing characteristics and strong power, then the offensive side behind a certain distance behind it cuts out a few times and loses power, and cannot control the aiming of the body, then he has to Diving speeds up again, and when the defender on the higher side dives down, he becomes an attacker ... A vertical turning action will occur here, as described in detail later.

Conversely, if the distance between the two sides is close during the ascending shear, the attacker at the bottom will have a greater chance to hit the defender. In the other case, if the defender is not as good as the attacker at the bottom, it will rise The speed is getting slower and slower, and then the attacker will catch up. At this time, the defending body is almost out of control, and there is no energy to change direction, and it becomes a fixed target hanging in the sky, a "sitting duck".
