用炮怎么解决电磁炮有后坐力吗Q Q

若大型战列舰的前后主炮同时同向开火,巨大的后坐力有何影响?如何克服?
虽说是齐射,但是同一炮塔上的炮管在发射时还是有千分之一到千分之二秒的时差的,并且炮塔里的反后坐力装置也会把舰炮射击产生的后坐力传到整个船身,以免后坐力过大导致船身倾覆~

Experiments have shown that this velocity varies between 1,200 and 1,400 mps. depending on the muzzle velocity of the weapon. For purposes of these calculations we will use 1,200 mps or 3,937 fps.&br&计算发射药燃气动能&br&Average outflow velocity of propellant gases(平均燃气喷射速度): w = 3,937 fps&br&Gas Kinetic Energy(燃气动能) = 0.5*((Wc/g)/2)*w^2 = 78.29*10^6 ft-lb&br&To compute the Kinetic energy of the recoiling parts, we must determine the velocity that they would achieve if allowed to recoil with no retarding force. This is commonly referred to as the free recoil velocity. To account for the difference between the velocity of the projectile and that of the propellant gases, we will use the aftereffect coefficient B which is defined by the relationship:&br&计算后座部件动能&br&w = B*Vo, therefore B = 1.5748&br&Free Recoil Velocity(自由后座速度): Vre = (((Wp/g)+B*(Wc/g))/(Wr/g))*Vo = 37.236 fps&br&Recoil Energy (后座能量)= ((Wr/g)/2)*Vre^2 = 5.387*10^6 ft-lb&br&The rotational energy of the projectile is small by comparison and can be neglected.&br&弹丸的旋转能量极小可以忽视。&br&The overall mechanical energy is only a part (40 to 50%) of the chemical energy of the propellant, since a considerable portion of the energy is carried off as heat by the propellant gases, or transmitted to the gun barrel.&br&总机械能只是发射药化学能的40%-50%,其余部分作为热能被燃气带走,或传递给炮管。&br&Ref. Rheinmetall Handbook on Weaponry, 1982, chapter 9.&br&Now, with these factors in mind, here are some additional calculations.&br&The momentum of a single projectile can be calculated as follows:&br&单一弹丸的动量&br&Projectile momentum (弹丸动量)= (Weight of projectile/g) * Muzzle velocity of projectile (弹丸重量/重力)×炮口初速&br&= (2,700 / 32.174) * 2,500&br&= 209.80 x 10^3&br&Momentum of the propellant gasses can be calculated from Leo's numbers as follows:&br&Propellant gas momentum (燃气动量)= (Wc/g) * w&br&= (650 / 32.174) * 3,937&br&= 79.54 x 10^3&br&Summing these:&br&两者的和:&br&Projectile momentum + Propellant gas momentum = 209.80 x 10^3 + 79.54 x 10^3&br&= 289.34 x 10^3&br&The Free Recoil momentum calculation can be used as a check, as it should be about equal to the sum of the momentums of the projectile and propellant gasses.&br&后座动量应该和弹丸加燃气的动量大致相等。&br&Free Recoil momentum = (Wr/g) * Vre&br&= (250,000 / 32.174) * 37.236&br&= 289.33 x 10^3&br&The Broadside Momentum for 9 projectiles can now be calculated as follows:&br&9发齐射的动量:&br&Broadside Momentum = 9 * (momentum of projectile + momentum of propellant gasses)&br&= 9 * (209.80 x 10^3 + 79.54 x 10^3)&br&= 2.60 x 10^6&br&Using Greg's formula, the velocity of an Iowa firing a 9-gun broadside can be recalculated as follows:&br&计算IOWA在齐射后的速度:&br&Mass of broadside * Velocity of broadside = Mass of ship * Velocity of ship&br&齐射质量×速度=船质量×船速度&br&As the Mass of broadside * Velocity of broadside term is equivalent to Broadside Momentum, this formula can be restated as follows:&br&因为齐射质量×速度等于之前计算的齐射动量,推得:&br&Broadside Momentum = Mass of ship * Velocity of ship&br&齐射动量=船质量×船速度(横移速度)&br&Solving for the velocity of the ship and using the above calculated momentum figures:&br&计算:&br&Velocity of ship (船横移速度)= Broadside Momentum / [Mass of ship] (齐射动量/船质量)&br&= 2.60 x 10^6 / [58,000 * (2,240 / 32.174)]&br&= 0.64 fps&br&So, the ship's velocity ON ICE with the guns firing at zero degrees elevation would be about 7.7 inches per second rather than the 6 inches per second calculated above. When one considers that any sideways motion of the ship through water is actually resisted by the wall created by the hull of the ship, whose wetted surface is about 860 feet long and 38 feet deep, then it can be easily understood that Dick Landgraff's comment above, &theoretically, a fraction of a millimeter,& is closer to the truth.&br&结论:IOWA在冰面上以0角度齐射造成到船体横移速度为每秒7.7英寸。考虑到横移会被船体在水中部分阻挡,而船体的水线长度为860英尺,吃水38英尺,具体横移距离应该不到一毫米。&br&&br&仔细看了还有一句蛮好玩的没翻译&br&我补上:&br&&br&&br&所以呢,Dick Landgraff所说的&br&“理论上,稍微大概好像差不多1毫米吧”&br&就很容易理解而且接近事实了~&br&&br&&br&&br&&br&&br&你还觉得,后坐力很大吗?

怎么给长身管火炮减小后座力?
在炮口安装火焰反冲制退器, 或在炮尾设置喷气孔等等.
1、超长后坐技术
其实就是增加后坐长度以减轻后坐,不管是单级后坐还是2级后坐,原理都基本相当。
2、无后坐力技术和膨胀波减小后坐力技术
无后坐力技术是将燃气后喷或者抛射平衡体来抵消后坐,膨胀波减小后坐技术类似,是炮弹通过炮膛的时候突然打开炮尾减少后坐,弹丸初速有点影响。
3、电(磁)流变技术
此技术在汽车离合器/减振器上试用效果很好,火炮还没有实际应用,尚在研究,可以取代弹簧/气体压缩/液体射流等。
4、炮口制退技术
炮口制退器,一般按原理分为冲击式和反冲式两种
冲击式制退器,是在炮弹出膛后,高压气流进入制退器腔室,迅速膨胀冲击反射面,然后从侧孔排出,部分从弹孔排出。为了充分利用气体效率,从单室发展到双室和多室,但是也不能做的太大,否则其重量对平衡力矩、结构都有不良影响。
反冲式制退器,是将燃气通过较小的制退腔,少量膨胀后直接向后喷出,利用高压高速气流的反作用力制退,气流喷出方向与炮膛夹角越小,有效作用力越大。
炮口制退器约能减少30%-60%的后坐力,效果很
