子彈真的會轉彎 二公里內全命中

美國《數字趨勢》網站報導,美國桑迪亞國家實驗室(Sandia National Laboratories)近日研製出一種自動導向智能子彈,能根據目標位置轉向、旋轉,輕易射中二公里外的目標。由於這種子彈能夠在多種槍支上使用,如果流入民間,人人可以成為狙擊手兼神槍手。

在軍事上,激光也被用來攔截導彈;但據報導,這種長約四英寸(約10.16厘米)智能子彈,與激光指示器一同使用後,可產生自動導向的功能。

報導指出,子彈外圈的光學傳感器能感應到追蹤目標的激光束。子彈內部也帶有多個用於與外界交換信息的傳感器,它們的共同協作使得子彈能跟隨目標,自動導航,最後射中目標。

簡單說,這種子彈裝有光學傳感器以及微小的導向翼,傳感器探測到的信息經過處理後,推動子彈內的馬達,進而調整微小導向翼的位置,改變子彈飛行的線路。它在發射後以音速前進的同時,子彈飛行軌跡可以在每秒之內調整三十次。

桑迪亞實驗室通過計算機進行空氣動力學模擬測試發現,無自動導向的普通子彈前進一公里至少偏離目標9.8米, 但這種智能的自動導向子彈同樣情況下只會偏離0.2米。

這項研究是由美國洛克希德•馬丁公司下屬的實驗室完成。研究人員說,他們已經完成了現場試射和計算機模擬,目前仍然有一些技術問題需要解決。但是產品將會投入使用,他們對此很有信心。

據報導,這種子彈能夠在多種槍支上使用。雖然這一研究最初僅是為軍方服務,但科學家稱,它也可能為執法部門服務,或作商業用途,比如用於獵槍。但分析家擔心它流入民間,成為非法的殺人利器。

'Smart bullet' hits targets a mile away

Uses tiny fins to steer itself toward anything targeted by a laser beam


A tiny light-emitting diode, or LED, attached to a self-guided bullet at Sandia National Laboratories shows a bright path during a nighttime field test that proved the battery and electronics could survive the bullet's launch.

Smart weapons have been growing smaller since the first guided cruise missiles took off with a roar. Today's soldiers may soon shoot farther and more accurately with a new "smart bullet" that uses tiny fins to steer itself toward anything targeted by a laser beam.

The 4-inch-long bullet has guidance and control electronics to steer its fins in midflight as it homes in on a target. Continual course adjustment means the bullet can hit laser-designated targets at distances of more than a mile ― a huge leap over military-assault-rifles such as the M-16 that have an effective maximum range of just over a third of a mile.

"We have a very promising technology to guide small projectiles that could be fully developed inexpensively and rapidly," said Red Jones, an engineer at Sandia National Laboratories in Albuquerque, N.M.

This is not one of those bullets that get their accuracy from spinning as they are fired out of a "rifled" gun barrel that has grooves to create the spin. Instead, it resembles a dart with a forward center of gravity and tiny fins that allow it to fly accurately without spinning. A tiny nose sensor allows the bullet to home in on laser-designated targets to deliver the accuracy and range of an expert sniper.

As the bullet flies through the air, its early motions allow for course corrections 30 times per second. But its flight path also steadies the longer it's in the air ― known to gun experts as "going to sleep" ― to ensure better accuracy at longer range.

"Nobody had ever seen that, but we’ve got high-speed video photography that shows that it’s true," Jones said.

Using the patented system, built from commercially available parts, a bullet can hit within eight inches of a target more than half a mile away. Unguided bullets could miss a target at the same distance by almost 10 yards.

Jones came up with the idea while hunting with Brian Kast, a fellow engineer at Sandia National Labs. The two engineers enlisted more colleagues to help develop the system,  and Sandia is now looking for a private company to help complete testing.

The engineers may have to consider the appropriate gun to pair with their smart bullet. Most modern-day guns, with the exception of some shotguns and less-lethal riot guns, use rifled bores instead of the smooth bores required by the new bullet.

But the Army has already begun putting smarter weapons in the hands of soldiers, with a backpack-size suicide drone capable of loitering overhead, and an airburst grenade launcher that explodes its round at precise ranges. If Sandia Labs can perfect its smart bullet, it is likely to find eager buyers among both the military and law enforcement.
