We are safe here inside the country because our soldiers are at risk out there at the line of control. Many times they got hurt by bullets, bombs and many impacts but they have no option except moving ahead and fighting with the enemies.
In our cities also cops also get captured in many dangerous riots but they have no option except entering in it and stopping the riots. In many situations we the normal people also get captured in situations where we have no option except fight and self defense for that time.
In all this situations ...
The X is a miniature launcher that can be used to propel metallic shells at a pre-determined target. It acts as a lilliputian simulator of a ballistic launcher. The robot perceives the target and adjusts the launching arm accordingly using various projectile motion formulae. Eventually, a tiny metallic bullet shall be launched onto the target.
The Building Blocks
1. The Aluminum Chassis
The Aluminum Chassis serves as the base to the bot.
The Laser-Eye Sensor System
The Laser-Eye Sensor system works as the eyes of the project. A 50 mW laser pointer is directed on a flat ...

Air transportation of goods is the fastest mean of distribution; for difficult access areas it is also the most convenient way of transporting some products, especially perishable ones. Yet it is also a very expensive way of transportation.
The idea is to make air transportation of goods affordable to the majority of people. This will be done by designing a fully autonomous aircraft with a payload in the range from 100 to 250kg. This aircraft will have no need of human intervention during normal operation, and will offer a cheap alternative to distribute products to small towns, villages ...
I propose to produce low cost unmanned moon rockets for schools and universities. The idea is to bring space exploration to the next generation by making an affordibility goal of under $10,000. The rocket being unmanned will allow it to be light weight and managed by fewer parts with a focus on petite performance. As a result each school could have their own space program leading to the reality that space is the last frontier for mankind.
Combining current space programs learnings from NASA, Space X, LDRS, Kerbel with Ardruino Makers and RC clubs we would produce a 3 ...
The basis idea would be to establish a network of entities and organizations interested in seeing the USA lead the effort towards producing Electric Flight Propulsion systems.
This can only be accomplished by the collaborative efforts of universities, private companies, airports and research institutions.
It is through this effort that many will be able to secure their interests in flight by lowering the operating costs associated with flight and allowing a lower cost of attaining the minimum hours required by the FAA for career ...
This is a B.E Aeronauical Final Year Project.This project deals with selecting, modelling and CFD analysis of cyclocopter blades. Two NACA series airfoils, viz. NACA 0010 and NACA 0012, are used. The blades are then modelled using Catia V5R20 by importing the coordinates from www.airfoildb.com using Macros. The pitch angle of the blades is determined using empirical relations for a single flight condition, i.e. at take-off. The modelled blades are meshed using ICEM CFD V14.5 and will be analysed using Fluent V14.5. The blades will be further modified by sealing the sides of the blades and adding winglets and ...
NASA's Constellation Architecture Team defined an outpost scenario optimized for intensive mobility that uses small, highly mobile pressurized rovers supported by portable pressurized Deep Space Habitat (DSH) modules that can be carried between locations of interest on the lunar surface. A compact vertical cylinder characterizes the DSH concept, where the large diameter maximizes usable flat floor area optimized for a gravity environment and allows for efficient internal layout. The DSH module was designed to be landed on the lunar surface and carried by the NASA Jet Propulsion Laboratory All-Terrain Hex-Limbed Extra-Terrestrial Explorer (ATHLETE) robotic heavy-duty mobility system. The DSH ...
Our work describes the design, fabrication and flight testing of an RC aircraft (for surveillance) powered with an Electric Ducted Fan (EDF). The configuration and layout of the aircraft was inspired by MiG-29 and F-35B; hence it has a swept high wing, aft horizontal tail and twin vertical tail configuration. It has a single short fuselage with centrally mounted EDF at rear, with a belly intake. A methodology for conceptual sizing and design calculations was developed, which included weight breakdown, drag characteristics, constraint analysis, final sizing and performance estimation. The aircraft was sized for rolled takeoff and landing, but ...
In order to locate a downed aircraft in water, a faster method might be possible, and cost less for the search. Minor modifications might allow this system to be used on lost aircraft that are not visible from the air.
An array of small, inexpensive repeaters that can be set for various water depths could narrow down the search area quickly.
The device is a plastic sphere with a listening device circuit on board, and a long life LiPo battery. It also has an acoustic transmitter that is more powerful and longer lasting than on-board black boxes.
The devices ...
The idea aims to generate more lift out of the traditional airfoil arrangement. The airfoil shape will contain a duct as shown in figure. The air inside the duct will again follow an airfoil contour only. Although the air flow to the main contour will get reduced, still the net lift will be increased because of increased contact area of divided flows. This can be easily shown using principles of fluid and flow mechanics. This will add up to the lift generated by main airfoil in accordance with Bernoulli's principle. So, now lift by both the contours will add ...
