anti hijack system for aeroplanes pdf

ABSTRACT

An anti hijacking system for an airplane to be operated during flight. A partition or barrier located immediately aft of the pilots cabin is adapted to be raised dividing the aft section longitudinally into port and starboard areas, the floors of which are dropped on command to lower the hijacker into a capsule in the belly of the plane. The capsule is releasable through opened bomb bay doors having attached thereto a parachute for safely returning the hijacker within the capsule to earth. ....etc

More Info About active adaptive phassed array radars

a phased array is a group of antennas in which the relative phases of the respective signals feeding the antennas are varied in such a way that the effective radiation pattern of the array is reinforced in a desired direction and suppressed in undesired directions. Phased array transmission was originally developed in 1905 by Nobel Laureate Karl Ferdinand Braun who demonstrated enhanced transmission of radio waves in one direction. During World War II, Nobel Laureate Luis Alvarez us ....etc

Nanomaterial use in construction, in coatings, in site remediation, and on invisible planes.The Israel-based YnetNews is Reporting that an Israeli company called Nanoflight has successfully run a test on dummy missiles that were painted with the nano-enabled coating and have shown that radar could not pick them up as missiles. The nanocoating achieves its radar trickery by absorbing the radio waves emitted by the radar and scattering them as heat energy enough so that when the radar gets the bounced back signal it is not regular enough to indic ....etc

HIGH SPEED TRAINS
1. INTRODUCTION
When English inventor Richard Trevithick introduced the steam locomotive on 21 February 1804 in Wales, it achieved a speed of 8 km/h (5 mph). In 1815, Englishman George Stephenson built the world's first workable steam locomotive. In 1825, he introduced the first passenger train, which steamed along at 25 km/h (16 mph). Today, trains can fly down the tracks at 500 km/h (311 mph). And fly they do, not touching the tracks.
There is no defined speed at which you can call a train a high spee ....etc

fabrication of hydraulic disk brake ppt

Brakes play a very important role in every industry and vehicle. A brake is a mechanical device which inhibits motion and use friction energy to convert kinetic energy into heat. Brakes are usually used on rotating axles or tires, although may also take other styles such as the exterior of your going substance (flaps deployed into mineral water or air). Many motor vehicles employ a mix of braking mechanisms, for example lug race cars and trucks together with both equally wheel brakes and a parachute, or ....etc

Welding

Welding is the process of joining together pieces of metal or metallic parts by bringing them into intimate proximity and heating the place of content to a state of fusion or plasticity

following are the key features of welding:
The welding structures are normally lighter than riveted or bolted structures.
The welding joints provide maximum efficiency, which is not possible in other type of joints.
The addition and alterations can be easily made in the existing structure.
A weld ....etc
