How can you drive a Flying Car?

A flying car which is also known to all as a aircraft in street and people can take tour for a short duration or long duration. In whole world or Automobile sector one can see two types of motor one is auto and another is manual, which is more prefer by yourself. Most of the driver in aircraft prefer automated motor. In everyday many company and many scientist try to make a car which is continue or drive in air and street but they are failed to manage it for a long duration. Glenn Curtiss who is chief of Wright brother designed aircraft in world first time. But it is try to jumped and it is successfully jumped and can not fly. After than all scientist do not stop working in automobile sector for trying to make a aircraft. Waldo Waterman first make the aircraft in 1910. In 1937 firstly go to air with his car Waterman Arrowbile which take attention from all people and amazing to all. In 1940 Jess Dixon fly his car in sky air by using automobile. But some unexpected scenery we seen in Newspaper and TV shows when someone try to fly in sky in 1971 Mizar , developer name is Henry Smolinski who is died by crashed. In 1990 AviAuto , Developer name is Harvey Miller who is make this concept. But in 2009 STOL aircraft , Developer name is Michael Robert Dacre who is killed by crashed.

Definition of Friction and Brake

Friction is main bad effect of a motor. Friction reduce a motor efficiency. Friction mainly create in a motor for it’s corrosion or speed ratio on spin. In a motor flywheel adjusted in drive wheel. In a gear ratio it mainly depends on gear and flywheel transfer energy on drive wheel. In a car or heavy load carrier vehicle used spring for reduce vibration and friction reduce generally use oil especially used in lubrication. For friction reduce one should firstly should select a metal which is help to reduce corrosion that’s means high resistance corrosion. Brake is also more important issue for a vehicle for it speed is slow down. There are three types of brake such as electromagnetic, disc and drum brake. Kinetic energy change to heat energy a vehicle speed reduce. Most of the car and vehicle use hydraulic brake which based in 6 steps and depends on 6 parts. These six parts are valve, road wheel, pedal, cylinder and boost. Electromagnetic brake is more popular for it’s more fa...

Mechanism of Solar Collector for Flat Plate

Solar collector main theme is collect radiation from sun and it transfer to heat energy or electricity to other storage such as a battery. One can use various types of solar collector such as a disk, flat and tube in thermally. In solar collector radiation absorb but the amount of supply heat is greater than absorb of heat. Radiation is mainly depends on environment, place, temperature, sunlight and air. For running a turbine solar collector used for initially running. If a collector any one compare concentrating solar and non concentrating solar collector there have basic difference such as concentrating solar has more benefits because it received radiation in whole area. In 1950 two person whore they Hottel & Whillier give a new theme to us for flat plate solar collector which has more benefit. A flat plate solar collector has some gradient such as i...

Why Coal is limited for world people?

Coal is a natural source of energy. But has limitation in earth. Coal is made from based on carbon. And other metals also contain such as H (hydrogen), S (Sulfur), N (nitrogen), O(oxygen). Coal is harder than any other metal. Coal mainly found in Soil, By using coal and give high pressure people can produce high temperature which is used by people in various ways such as produce electricity. Coal is largest natural energy in world anthropogenic. By using coal there have create much amount of CO 2 (carbon die oxide) which more bad for our environment and polluted our air. By using the amount of pollution is more than using natural gas in produce of electricity. When produce 1 MH (Mega watt hour) produce electricity carbon die oxide produce about two thousands pounds by using coal. And when also same amount of electricity produce by using natural gas carbon die oxide produce one thousand pounds. For reducing the emission of CO ...

Packing, Seals and Gaskets

Packing, seal and gasket resists the flow of fluid from machinery face, head, joint and machinery gap or clearance. Packing materials: Fiber, asbestos, cotton, synthetic materials, plastic, Teflon, graphite etc. Packing structure: Twisted, Braided and Consolidated. Gasket: A gasket is a mechanical seal that fills the space between two mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow " less-than-perfect " mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials, such as gasket paper, rubber, silicone, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or a plastic polymer (such as polychlorotrifluoroethylene) ...

what is the difference between long shunt and short shunt dc generator?

How do they differ from normal generator? Draw their V-I characteristics and explain them? In short shunt connection the shunt field is connected directly across the armature terminals and the armature connection equals the sum of the shunt field current plus the load current . In this instance the load current flow s through the series field winding so that the load current and series field current are one and same. In long shunt connection the voltage across the shunt field is the same as the terminal voltage of the generator and current in the armature will be the current in the series field. The armature current equals the shunt field current plus the load current. A shunt generator has the field circuit connected directly across the armature. As more devices connected in parallel the load on the generator increases that the generator current increases which...

Why a dc generator fails to build up voltage?

How can the problem be remedied : No residual magnetism, reversed field connection and high resistance of field circuit are responsible for the failure of build up process of a dc generator. The factors are explained below: No residual magnetism: For the starting build up process requires some residual magnetism in the magnetic circuit then no voltage will be generated that can produce current flow through field circuit. Reversed field connection: The voltage induced inside the coil of field circuit due to residual magnetism that can permit the flow of current. For the following direction of this flux will be created and the direction of this flux will be same direction as the residual flux. If the field connections are reversed the lines of flux produced by current flow will oppose the residual flux, as a result generate voltage will decrease rather than increase. So voltage build up process failed. Field circuit resistance ...
