But lucky for them, Wald was a genius. The theory is that keeping a laser trained on one spot is difficult, especially if you, for example, rotate your ship. The next step up is some form of advanced carbon material, ranging from diamondoid armor to nanotubes.
Also, increases the effective thickness by the secant of the angle. They did an analysis of bullet-holes in the bomber aircraft and made Chart 1 see above which they proudly displayed to Wald. This comes under the heading of "not keeping all your eggs in one basket".
Apparently they rely on their handwavium deflector shields to do the job, which is great until you run out of power. You do not want a form that is soft or easily powdered, or the vapor action under laser impact will blow out flakes of armor, allowing the laser to penetrate much faster.
CoaDE users recommend spider silk. This energy is what powers all of the phenomena associated with the impact that are not part of the debris cloud. Various metallic armors are likely to be the cheapest option available, but suffer from a very high mass to strength ratio and are not terribly effective against lasers.
This is why every recon captain I ever served under had an ulcer and the temperament of a grouchy bear. The Doradus was armed with the latest in ultra-scientific weapons: The absorption layer behind the Whipple shield should have a high melting point, specific heat capacity, and thermal conductivity, as the debris will cause significant heating high-energy, remember?
The biggest problem is that we are unable to produce industrial quantities of these materials today, and the exact properties achievable are not known with any degree of accuracy.
So once you have delivered enough pulses to chew through the entire thickness, the rest of the pulses get through. However, this is increasingly wasteful of mass, and possibly unnecessary see long-range armoring section for rationale. It seems to me this vital part of naval design would not be overlooked in space warship design.
During World War 2, the United States had several top-secret programs where mathematicians and statisticians helped with the war effort by fighting with math. Some also report great results with nickel-phosphorus microlattice and ultra-high-molecular-weight polyethylene UHMWPE. This analysis does not take into account additional penetration which might come from the kinetic explosion of the projectile.
The bomber crews figured they had the same chance of surviving a given mission as winning a coin toss, you were quite likely to die long before you got your fifty-mission crush. Not that that stops people from taking a pot-shot or two at you anyway on general principles.
I do agree, though, that a lot of recon is going to be done by masquerading as civilian traffic and other presumptively harmless things comets, say, comets are always good Reinforced carbon-carbon ceramic is another choice with amorphous carbon an acceptable substitute in a pinch.
Luke Campbell has suggested layering SiC with tungsten to gain a sort of composite armor which would be effective both against lasers and kinetics thanks to high refractory properties and the alternating high density-low density layers give a form of stand-off Whipple armor.
Millard started with the fact that apparently Kansas is a meteorite magnet. You have to wreck many compartments, or very specific compartments, in order to mission-kill the ship. In other words, the mass per unit area of the shield for spherical projectiles needs to be equal to the diameter of the projectile times its density.
Beyond the obvious benefits of making it easier to control atmospheric leaks, a space warship built with many compartments that can be isolated would gains a structural benefit in combat.
Zirconium and hafnium are used to enhance this effect, and there has been research into coruscatives, which contain their own oxidizer and function in a similar manner.
In space, you cannot see the enemy with the naked eye anyway, so you might as well put your command centers where the enemy has to destroy the entire ship to get at it.If a vertical water jet moving with velocity ‘V’ made to strike a target (Vane) which is free, to move in vertical direction, force will be exerted on the target by the impact of jet.5/5(4).
Impact Of Jet On Vane Apparatus. Impact Of Jet On Vanes Apparatus - (SIFVA) Ask for Price. The Set-up consists of two sided clear fabr1catt0n. Water is fed through a nozzle and discharged vertically to strike a target carried on a stem, which extends through the cover.
A weight carrier is mounted on the upper end of the stem. 11/12/ 1 IMPACT OF JETS Dr. Sanghamitra Kundu Outline box2 Introduction box2 Force exerted by fluid jet on flat plates box5 Stationary flat plate box5 Moving flat plate box2 Force exerted by fluid jet on vanes box5 Stationary curved vane box5 Moving curved vane%(1).
Experiment 4 Impact of a Jet Purpose The purpose of this experiment is to demonstrate and verify the integral momentum equation. The force generated by a jet of water deﬂected by an impact surface is measured and compared to the.
Defensive Systems. The innermost of a starship’s defensive systems is its killarney10mile.com primary armor is a multilayer (“honeycomb”) system over the core hull, composed of multiple vacuum-separated layers of refractory cerametals, sapphiroids, and artificially dense metal nanocomposites, strapped together via flexible, shock-absorbing forms.
impact of jet on vanes When a plate is placed in the path of a jet, the jet exerts a force on the plate. This force can be calculated from the impulse-momentum equation.Download
