Unmanned aircraft has unpredictable flight pattern.
Inspiration from Nature
Moth out-manoeuvres a bat by adopting an unpredictable flight pattern and causing radar disruption.
Modern warfare is undergoing a major paradigm shift. One of the epicenters of this change is high-energy laser weaponry. It has phenomenal application in air-defense because the accuracy and speed of laser can render even the most advanced jet fighters sterile. A stealth bomber needs to be designed which can counter such a threat from enemy.
A moth has to defend itself from a similar threat. It must dodge a lightning fast airborne attack of bat which is a much bigger predator than itself. Besides being instant, a bat attack is ultra-precise due to its dependence on radar-tracking system instead of visual engagement. A moth needs to meet two goals:
1. The returning frequency of a bat should be disrupted so that the speed of its attack becomes its own drawback.
2. The flight trail of moth should not leave an easily decipherable pattern for the bat.
Following these two objectives, a moth has evolved following two functions:
1. It generates its own radar frequency which deranges the frequency of a bat and
2. Its anatomy (structure and materials) can support a flight pattern with negative-stability.
F-16 was the first plane deliberately designed for negative-stability in air. Its maneuverability in dogfight is dreaded to this day. However, an unpredictable and disruptive flight pattern which can dodge laser needs much more sophistication in its chaos. Lockheed Martin F-35 can make a vertical take-off and is equipped with state-of-the-art stealth technology. Similarly, China and Russia recently tested the Ramjet engine technology which consumes oxygen from atmosphere, reaching speeds up to Mach 6. All these technologies must be brought together to configure a flying machine truly capable of out-maneuvering a high energy laser beam.
An unmanned aircraft dodges laser through its negative-stability flight system, ramjet-engine thrust and radar abruption. A stealth bomber is designed which mimics the anatomy of a moth in terms of its flexibility (1, 23) and weight distribution. The propulsion system (14) is based on ramjet technology (15) and the thrust outlets (2, 6, 8) are located at strategic places to ensure maximum unpredictably and speed.
