Currently, propeller pitch control uses three approaches: it is based upon either hydrolic oil pressure, mechanical control using lateral motion along the axis of the drive shaft, or electric motor control with the drive motor embedded in the hub. All three of these techniques are either expensive to manufacture and install, or expensive to maintain due to high wear rates or the close machine tolerances required.

This device combines the action of a vehicle’s shock absorber and springs. Two of the major components of a suspension system are shock absorbers and springs. At first glance, they seem to have completely opposite effects; the spring bounces back, and the shock absorber keeps you from bouncing back. In actual fact, however, the difference is simply a matter of how energy is used. In the case of a spring, the energy from the movement

This residents of this 'Urban Sprawl' will make daily trips to a from a multitude of destinations making large scale mass transit systems inefficient in dealing with fragmented journey patterns. The reliance on high cost and high impact infrastructure would become meaningless as governments push towards carbon neutrality. To eliminate

The benefits of a spherical shape system composed of modules is that its outer perimeter is always shielding both harmful radiation from the sun while constantly converting solar energy.
The modules themselves can constantly be rearranged and be outfitted for specific purposes such as research or work, harvesting such as plants and personal care.

The objective of this project was to design a watercraft that combines the throttle cranking adrenaline rush of a jet ski with the unobtrusive spray in the face good time of surfing. A key element of creating the fun factor in a watercraft is the seating position. Certain seating positions enhance the feeling of speed and connection with the water. The MantaCraft is composed of four major elements, which were the focus of my design.

Current metropolitan passenger movement is generally concentrated in three areas: automobile, bus and rail, with user numbers descending in that order and potential energy efficiency ascending in the same order. The attraction of the automobile is mainly convenience for the owner, so alternatives must take this into account, but metropolitan stop and start travel is detrimental to mileage and causes increased emissions. Bus routes provide a partial alternative but they offer inflexible operation regarding routes

The VTOL aircraft is the ultimate aircraft. It can take anywhere without the use of a runway. Though the helicopter is the most successful VTOL aircraft it operate at relatively low speed. This has called for the development of a conventional aeroplane which can take off an land vertically. In these aircraft, vertical thrust for take off is achieved by tilting the entire wing or engine on which the rotor is mounted. This has made

The idea is to use elevation loss to accelerate small steel or ductile iron wheeled passenger trolleys to sufficient terminal speed to coast to the next stop.
On arrival to the next stop linear motor elements would power the trolleys back up to the next stop. Design would emphasize low cost an simplicity of the individual trolleys.
Service would be frequent. Cars would not have brakes or an more of an electrical system than some

The majority of vehicles use combustion of fuel to impart motion to a vehicle. Even today’s and near-future Hybrids and Electric Vehicles use a gasoline engine for some functions. There is a negative impact on the environment both in emissions and in the methods and processes used to obtain fuel. Eliminating the gasoline engine would not only reduce our dependancy on fossil fuels, it would also reduce the weight, complexity and cost of

Since the induction of the automobile, technological advancements have consistently improved vehicle safety. Now so more than ever, technology is being applied in areas previously unfeasible- cars can now sense crashes, etc. However, despite these advancements, the key element of safe driving has been largely overlooked- outward visibility. Headlamps have gone from candlesticks to xenon bulbs over the past century, but still remain a source of light meant to illuminate vehicle surroundings. Headlamps are reasonably

I have designed an electromagnetic engine which is levitating inside the wheel which results in the removal of transmission system as well as all the internal losses.
My system works on the simple fact that opposite magnetic poles attract and same poles repel each other.
It is designed in such a way that it reproduces 40% of energy it used which can be used again.And at low speed its a very efficient electromagnetic engine.

However, most developing countries are facing problems related to traffic and transportation. Inadequate transportation facilities retard the process of socio-economic development in a country.
