there were three rotors that contained all 26 letters of the alphabet. What would happen was that when someone would press a letter on the keyboard‚ a different letter would pop up on the paper‚ such as A for E‚ D for G‚ F for Z‚ and so on. These substitutions occur because of the positions of the rotors on the inside of the machine. The rotors are first situated at any random letter in the alphabet and when the button is pressed‚ the letter that is at the beginning of the rotor is put onto the paper

How The Turning Rotor Makes A Helicopter Move Upwards How Does A Helicopter Work? In order to fly‚ an object must have "lift." Lift is what pushes something up. Lift is made by wings. Wings have a curved shape on top and are flatter on the bottom. That shape makes air flow over the top faster than under the bottom. The faster air on top of the wing makes suction on the top of the wing and the wing moves up. Airplanes get lift from their wings. A helicopter’s rotor blades are spinning wings. A helicopter

and collecting secondary data How the turning rotor makes a helicopter move upwards: The blades or rotors on a helicopter are used to produce a lifting force which gets the helicopter off the ground. As they spin around they cut into the air and produce lift‚ each blade providing an equal share of the lift. To produce this lifting force air must flow over each rotor. This is why the blades spin at an angle against the air. The shapes of the rotors are designed allowing air to move faster over the

Controlled Assessment – Helicopters You need to research information (using the internet) that includes answers for the following questions: 1. How the turning rotor makes a helicopter move upwards 2. How the rotor is made to turn in a helicopter and in an autogyro 3. How autorotation is used to help land a helicopter safely if the engine fails 4. Why a helicopter; falling during autorotation‚ could reach a terminal speed without the pilot changing any controls 5. The effect of the weight of

centrifugation tubes is called the centrifuge rotor. Centrifuges are designed so that a number of different rotors can be used by the instrument. There are three types of centrifuge rotors: fixed angle rotors‚ swinging bucket rotors‚ and vertical rotors. Fixed-angle and swinging-bucket rotors are the most commonly used. In a fixed-angle rotor‚ the centrifuge tubes are spun at a fixed angle‚ which is usually approximately 35 degress. Fixed angle rotors are most commonly used for pelleting cells and

or pneumatic. ROTOR * A SYNCHRO ROTOR is composed of either a single coil of wire wound on a laminated core or a group of coils wound in slots in a laminated core. The laminated core is rigidly mounted on a shaft that is free to turn inside the stator. Two slip rings are mounted on one end of the shaft to supply excitation voltage to the rotor. There are two common types of synchro rotors - the salient-pole rotor and the drum or wound rotor. * The SALIENT-POLE ROTOR has a single coil

unmanned aerial vehicles. Due to their precision‚ gyroscopes are also used in gyrotheodolite to maintain direction in tunnel mining. Within mechanical system or devices‚ a conventional gyroscope is a mechanism comprising a rotor journal to spin about one axis. The journals of the rotor being mounted in an inner gimbal ring. The inner gimbal is journal for oscillation in an outer gimbal for a total of two gimbals. The outer gimbal or ring‚ which is the gyroscope frame‚ is mounted so as to pivot about

The exciting coils are connected in series to two slip rings and direct current is fed into the winding from an external exciter mounted on the rotor shaft. The stator is wound for the same number of poles as the rotor poles. As in the case of an induction motor‚ the number of poles determines the synchronous speed
