Most of the energy is wasted in hot gases\/noises (34%), in barrel heat ( about 30%), in barrel friction (about two%) or is just not used (about 1% of the power is even not released because a tiny element of the powder didn&#8217;t go off).<\/p>\n<p>(*two)So what can we do? A longer barrel means that hot gases are going to give a lot more energy to the bullet. We can also use metamaterials wich deflect waves (here shock waves) and give there power to the subsequent round fired. We can also use Pelletier systems to convert the heat in electricity and then give it to the next bullet fired. This can operate only if efficient power conductor are use. Wich indicates that the weapon will be heavier, will be costly, will have a low rate of fire but will be far more potent, acurate and have a longer range, thermal and noise reduction (except if there are no metamaterials about the muzzle or\/and if the bullet is supersonic).<\/p>\n<p>But in the ARET 2. weapon set, the barrel is replaced by a MHD generator wich converts the motion of the hot gases in electricity which is sent to a a bench of capacitors. These devices will then send an essential electric discharge to the rails wich will propell the bullet at higher speed. The ARET two. weapons are lighter, a lot more compact and even more effective than their ARET 1. equivalents.<\/p>\n<p>This leads to the meanings of the weapon set name &amp;quotARET&amp;quot which stands for Armes \u00e0 R\u00e9cup\u00e9ration de l&#8217;Energie des Tirs (shot&#8217;s power recovery weapons).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Check out these ultrasonic machining pictures: Apollo Lunar Modules Image by jurvetson A titanium deployment and downlock truss from the landing gear of the lunar module beckons in the corner\u2026 But the autopilot brain-in-a-box is much more fascinating.
