My Idea is about a drone with rifle. Some areas where for surveillance or any place where terrorist are present we can send this drone. Major 2 concepts to consider: recoil of gun and how to recognize face. Recoil surely imbalances the drone. So there are two ways to avoid this: [1.]By using hydraulic cylinders bed. [2.]By using spring bed. In first technique, (fig.1) by using few small hydraulic cylinders we can avoid backward movement of gun. When gun is fired shock is absorbed by hydraulic which negligibly affects drone’s stability. [2.]Using spring bed(fig.2), similar as hydraulic, spring bed ...
Conventional methods of surveying land consume a lot of time and are thereby quite expensive as it requires skilled personnel and manual labor. Inspecting larger areas at a shorter time is quite difficult to accomplish manually.We aim to solve this problem by using Drones for Aerially Mapping and surveying huge areas of land within a very short span of time. Data is acquired aerially, is processed as is given in a report like format. This report contains valuable Geospatial Data suited for survey calculations. The report is in a workable format and thereby can be used to generate 3D ...

Helicopters and planes perform significant roles in both armed forces and civilian life, with many duties being exclusive to one or the other. Helicopters are capable of vertical take-off and landing (VTOL) but are limited in forward velocity by the rotor tip speed, as well as being significantly louder than a similar sized light plane. Airplanes as well suffer drawbacks for particular uses, such as being unable to take off and land in small spaces, as well as needing fossil fuels to run, often required to be on board, or refueled only with aviation fuel. Recent advances in electric ...

This light tank concept provides effective and affordable defense for nations which cannot maintain fleets of 60 to 70 ton vehicles with huge logistic support requirements and destroys the paradigm that lethal vehicles are heavy vehicles. The Expeditionary Gun System (EGS) integrates a 105mm cannon directly into a semi-autonomous wheeled vehicle eliminating the rotating turret by harnessing the same suspension characteristics which provide extreme mobility to aim, control and stabilize the gun. This sixteen-ton design eliminates weight, complexity, cost, and armor volume; reduces fuel consumption and crew size; while providing lethality unavailable in its weight class.

The Saucer-Kush and Mothership-Jedia, shown in Figs.1&2, are a New Flying Object (NFO) propelled by the External Magnetic Field-Propulsion System (ExMF-PS); based on the Universal Energies (UE), derived from the new fundamental physics (http://exmfpropulsions.com). The detail characteristics of Jedia mechanism is shown in Fig.3, it consists of external bismuth 1 of the propellant mechanism, and an internal ferromagnetic protecting structure 2; both linked by beams 3, axels 14 and 27.
The driving, ascending, brake and stability forces are shown in Fig.3; where [A] is the ExMF Driving force (FExD) [B] is the ExMF Ascending Force (FExA) or levitation ...
Hover bike is a flying robot, which works on the principle of a combination of lift generation as in a helicopter, and maneuvering of a bike. With this technique humans will experience a new way of flying and driving in mid air. The hover bike has the ability of having Vertical Take-Off and Landing (VTOL), which is the general way of lift generation by helicopters. A well designed hover bike will be able to take a slow VTOL due to the low area of pressure distribution by the blades, and also due to high amount of weight concentration mostly near the ...

Education, military, agriculture among other fields are using drones to benefit the proficiency. Drones are used in almost all the operations as well as the industries nowadays because of their reliability, cost effectiveness and multifunctionality.
Jet packs are similar to drones because they are propelled into the air as a result of escaping gases/fluids. The hydro jet pack has been successfully designed and developed and used in various applications. Water Jet Fire Extinguisher system uses water jet as the propulsion system as well as a fire extinguishing agent.
Water Jet Fire Extinguisher is a type of hybrid drone that ...

I am designing a drone system that works as a bucket brigade that will carry and deliver a mixture of chemical foaming agent mixed with water to create fire suppression foam or products like Phos-Chek. The system is mostly autonomous using GPS mapping coordinates delivered to the drones by mesh network. The system is targeted at wild fires in grass or forest lands. Currently forest and grass land fires are fought with ground forces and aerial equipment. So the risk of life is great and the equipment is expensive both in initial investment and long term upkeep. Fire fighters ...
The report deals with the concept of using flapping wing as a mode of flight for light unmanned aerial vehicles. Using biomimetics, the study of a bird flight is made followed by the design proposal which mimics this bird flight mechanism. A detailed calculation is then made for calculating lift and thrust produced by a single wing including the benefits of diffuser lift provided by the unique wing design. Finally, the kinematic, aerodynamic and dynamic equations of motion are derived for the rear flapper.
Another means of reducing the negative lift generated during the upward stroke is by making ...
