The above shown hovercraft is a true hand made customised by my group. The details of this hovercraft will be given below .If anyone has any queries regarding this may contact me
Step 1: Introduction
A hovercraft, also known as an air-cushion vehicle or ACV, is a craft capable of travelling over land, water, mud or ice and other surfaces. Hovercraft are hybrid vessels operated by a pilot as an aircraft rather than a captain as a marine vessel. Hovercraft use blowers to produce a large volume of air below the hull that is slightly above atmospheric pressure. The pressure difference between the higher pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface. For stability reasons, the air is typically blown through slots or holes around the outside of a disk or oval shaped platform, giving most hovercraft a characteristic rounded-rectangle shape. Typically this cushion is contained within a flexible "skirt", which allows the vehicle to travel over small obstructions without damage. A Lithuanian Coast Guard hovercraft with engine off and skirt deflated. The same hovercraft with engine on and skirt inflated. The first practical design for hovercraft derived from a British invention in the 1950s to 1960s. They are now used throughout the world as specialised transports in disaster relief, coastguard, military and survey applications as well as for sport or passenger service. Very large versions have been used to transport hundreds of people and vehicles across the English Channel whilst others have military applications used to transport tanks, soldiers and large equipment in hostile environments and terrain.
Step 2: Unmanned Aerial Vehicle(UAV Drones)
Moto:- Our project is evolved from idea of making a drone which will work both on land and water. We got this idea from the hovercraft if we can make a unmanned drone then it will be very helpful for international water security it also protects human life since he doesn’t have to actually go to the danger zone . And now a days drone or UAV are the future of modern warfare for spying on the enemy acts In war the persons who knows where the enemy is what ammunition they have always Wins
Step 3: Design
The design should be perfectly done with the equal measurements . There should be 2 fans connected to a battery supply to simply rotate.(Only the measurements of the side fans should be done correctly) .
Step 4: Devices Required
1-Brushless electric motor
2-Wi-Fi control receiver to sync with the android phone
Step 5: Brushless Electric Motor
A brushless electric motor is an electric motor driven by an electrical input, which lacks any form of commutator or slip ring. The motor requires some form of alternating current to turn, either from an AC supply, or an electronic circuit. A brushless DC electric motor contains a synchronous motor and integrated power electronics that operates the motor from a direct current supply. A "permanent-magnet synchronous motor" (PMSM) or "permanent-magnet motor" (PMM) is a synchronous motor that uses permanent magnets rather than windings in the rotor. Electronic excitation control with integrated power inverter and rectifier, sensor, and inverter electronics is required for practical operation. Form-factors for the PMSMs are either axial flux, radial flux, transverse flux, or flux switching depending on the arrangement of components, with each topology having different tradeoffs among efficiency, size, weight, and operating speed. Also in the axial flux or radial flux form-factor, other brushless motors are the brushless wound-rotor doubly-fed synchronous motor system and the magnetic reluctance, which require electronic excitation control for practical operation, and the asynchronous induction motors, which is with or without electronic excitation control depending on the application. Conventional methods of electronic AC excitation control of electric motors, such as volt/frequency control, were available prior to the 1950s with at least mercury vapor thyratrons switching devices and modern age state of art control (or Field Oriented Control) became available in the late 1960s. Permanent magnet motors have been in existence since the introduction of electric motors more than one-hundred years ago.
Step 6: Wi-Fi Control Receiver to Sync With the Android Phone
Avionic presents the all new Wi-Fi 4Ch receiver for your RC planes and cars. All you need is your smart phone with a IOS (iPhone 4s and above) and Android platform. This unit will enable you to control your park flyer plane to around 100~120 meters in line of sight which is superb range for such a device. And yes not to forget RC Cars or boats range is around 60~70 meters. This unit also can be programmed for a failsafe function just in case of any lost of signal.Finally, you can control your R/C model from your IOS/Android device!. The app used to control the models are absolutely easy to use and can we downloaded here for Android and App store for your iPhone (just search in your app store for RC planes and RC cars to get the app). All it takes is a few seconds to link your phone and set up the esc and servos to this Wi-Fi unit. Use an input of 5~7.4V to operate this unitSpecification:Signal Type: Wi-FiCompatibility: IOS & Android Channels: 4 Ch.Range: 60~70 meters (car/truck/boat) / 100~120 meters (aircraft)Dimensions: 4.2cms x 1.4cms x 2.6cmsAntenna Length: 136mmWeight: 11g
Step 7: Gsm Module
A GSM modem is a specialized type of modem which accepts a SIM card, and operates over a subscription to a mobile operator, just like a mobile phone From the mobile operator perspective, a GSM modem looks just like a mobile phone. When a GSM modem is connected to a computer, this allows the computer to use the GSM modem to communicate over the mobile network. While these GSM modems are most frequently used to provide mobile internet connectivity, many of them can also be used for sending and receiving SMS and MMS messages.
Step 8: Making
The making of the drone was practically a great task for us as there were no images or refer links present on the internet which we could actually do it.
There are some images above which will guide you on how to make.
We modify and place the web cam on any side we want . But the GPS module should not be exposed outside as it will be affected by water in extreme conditions.
The battery and the brusless motor are to handle the flow of air which should be placed at the back side of it .
Step 9: Refer Block Diagrams
This the internal of the drone which basically is the inside process on how it works
Step 10: Future Scope
Ultrasonic and Infrared and temperature sensors for search and rescue
Automatic Threat detector
Satellite controlled resource finding Drone
Step 11: Conclusion
This project is a totally new drone system introduced in the world of UAV’s From this project we can make India a super power nation in military might as well. It is quite easy to deploy and control since android based system and we are familiar playing games. We will be protected an will be aware of the threats coming towards us our great soldiers and navy men will be protected and safe. We are planning to upgrade this technology by adding artificial intelligence to the processor so that it can take the co-ordinates of the area to be checked and return to the base by itself . Also we are planning to increase its reciver range by using SATCOM systems to control the drone increasing its area and decreasing its limitatiom

I have vedios showing the outputs of the drone and the real time feedback of the camera placed on the drone . Unfortunately i put on the vedios here .So any questions feel to ask...
