pdf on advantages and disadvantages of hovercraft

Hovercraft operate on a cushion of air and during their earlier years were considered to fly above the surface below. They generate a volume of lift air, maintained by a flexible skirt at a higher pressure than the atmospheric pressure above. Their weight is therefore balanced by the lift that is generated.

Our hovercraft use commercially available technology, are diesel powered, and use aluminium as the primary hull structure to make them easy to maintain and repair in the field.

The Pelton wheel is an impulse type water turbine. It was invented by Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water, as opposed to water's dead weight like the traditional overshot water wheel. Many variations of impulse turbines existed prior to Pelton's design, but they were less efficient than Pelton's design. Water leaving those wheels typically still had high speed, carrying away much of the dynamic energy brought to the wheels. Pelton's paddle geometry was designed so that when the rim ....etc

The Pelton wheel is an impulse water turbine. It was invented by Lestar Alone Pelton in the year 1870 s. The Pelton wheel draws impulse energy from moving water, as opposed to the dead weight of water as the traditional over water wheel. The water flowing from these wheels normally still had high speed, taking much of the dynamic energy brought to the wheel.

advantages and disadvantages of digital tachometer pdf

Tachometer (Revolution counter, tachometer, tachometer, the RPM gauge) is an instrument for measuring the rotational speed of the disk or, as in the machine.The engine or other device usually displays the number of revolutions per minute (RPM) on the calibrated analog dial, but digital displays are becoming more common. The word comes from the Greek (Tachos speed) and Metron ( measure). In fact the word tachometer and speedometer are of equal importance: a device that measures the spe ....etc

A beverage can is a metal container designed to hold a
fixed portion of liquid such as a carbonated soft drinks,
alcoholic beverages, fruit juices, teas, herbal teas, energy
drinks, etc. Beverage cans are made of aluminium (75% of
worldwide production) or tin-plated steel (25% worldwide
production). Since we use aluminium so frequently (75% of
worldwide production) it is important to recycle
aluminium. Recycling aluminium not only helps to keep
the landfills clear but it also saves energy. Recycling 40
aluminium beverage cans saves the ....etc

In a Pelton Turbine or Pelton Wheel water jets impact on the blades of the turbine making the wheel rotate, producing torque and power. Learn more about design, analysis, working principle and applications of Pelton Wheel Turbine.

Hydraulic Turbines are being used from very ancient times to harness the energy stored in flowing streams, rivers and lakes. The oldest and the simplest form of a Hydraulic Turbine was the Waterwheel used for grinding grains. Different types of Hydraulic Turbines were developed with the increasing need for power.

The goal of this ANTI THEFT WHEEL LOCKING SYSTEM project is to hinder the theft of bikes with the help of wheel locking system. The solenoid switch is used as the main tool to lock the front wheel of the bike. Solenoid is a device that monitors in linear motion. It includes plunger which moves in too and fro motion and is connected to the battery supply.
