  RADAR refers for Radio Detecting And Ranging, and it is based on the use of radio waves, as the name suggests. Radars, like wireless computer networks and mobile phones, emit electromagnetic waves. The signals are sent out in brief pulses that may be reflected by objects in their path, returning to the radar in part. Part of the energy is scattered back to the radar when these pulses encounter precipitation. Hearing an echo is akin to this notion. When you yell into a well, for example, the sound waves of your voice are reflected off the water and returned to you. The pulse reflects off precipitation and transmits a signal back to the radar in the same way. Based on this data,

 Automobiles on the ground, produce a force to propel us ahead. The engine turns the wheels, which push the car forward by pushing it off the ground. Because there is nothing to push off in flight, a new concept is needed to provide propulsion.  If you opened the fire extinguisher, a torrent of gas would be released, propelling you in the other direction. Sir Isaac Newton initially articulated the physics behind this theory in his three principles of motion in the 17th century. The turbine engine works on the same principle: it produces a force pushing the plane forward by blowing air out of the rear of the engine fast. The jet turbine engine is used to generate this fast-moving gas stream. This follows the 'Suck-Squeeze-Bang-Blow' concept. The illustration below depicts an engine with the various parts and their functions labelled.

 A radio controller is an important component in RC aircraft without this component we cant control RC aircraft. Another part that is as important as the radio controller is the receiver this component is installed inside the aircraft. The receiver's job is to catch radio controller signals and give them to other components such as servo, flight controller and ESCThe term "Channels" has two meanings in RC flying. To minimise confusion later, let's identify them now. The term "Channels" refers to the number of various items you may operate on a single aeroplane with a "4-Channel" radio. Elevators, Ailerons, Rudder, and Throttle are the four basic controls — there are four of them, thus you'll need a four-channel radio. If you wish to add features to your planes, such as flaps and retractable landing gear, you'll need two more channels, therefore a 6-channel radio is required. With more than 6 control channels, you can add cool extra features

A rotary engine is an internal combustion engine, similar to the one in a car, but, it functions differently from a traditional piston engine. A piston engine uses the same volume of space (the cylinder) to perform four separate tasks: intake, compression, combustion, and exhaust. These four duties are performed by a rotary engine, but each one takes place in its section of the housing. It's as if each of the four occupations had its cylinder, with the piston going continuously from one to the next. Dr Felix Wankel invented and developed the rotary engine, which is also known as the Wankel engine or Wankel rotary engine. The rotary engine, like a piston engine, relies on the pressure generated when a mixture of air and fuel is burnt. That pressure is contained in the cylinders of a piston engine, forcing pistons to move back and forth. The connecting rods and crankshaft turn the pistons' reciprocating action into a rotating motion that may power an automobile. The pressure of c

  The Bermuda Triangle is a mystery yet. This place holed a creepy mysterious story about the disappearance of aircraft and ships.  this mysterious place is located in the Atlantic Ocean between Florida, Puerto Rico and Bermuda. A lot of ships and planes have disappeared from this location some people call this place "The devil's triangle".Some of the pales and ships have never been found. There have been a lot of theories about this, please. Starting with a huge tornado to aliens and sea monsters. The first report was found in 1945 when five American torpedo bombers and the rescue pale vanished without a trace. The latest incident happened in 2015  " ElFaro " the cargo ship that disappeared in this region this ship disappeared on the 1st of October,2015 and was found wrecked on the bottom of the ocean on the 31st of October. 

this moveless creation of Robert Goddard. the rocket engine is not the same as a regular engine. A typical engine rotates a crank by igniting gasoline, which pulls on certain pistons. As a result, rotational energy is used to turn the vehicle's wheels. Rotational energy is also used by electric motors to turn fans and spin disks. The rotational energy used by a rocket engine is not used in its operation. They function as reaction engines. The basic concept is that the fuel contained within the rocket's body undergoes a chemical reaction as it exits the rocket's end. The thrust created by this reaction drives the rocket onward. This is an illustration of one of Sir Isaac Newton. nowadays rocket engines are used for different tasks. this creation is changed the human history.
