The composition of the Command Guidance system for the Titan I Intercontinental Ballistic Missile in the United States.
The principles and functions of the Command Guidance system for the Titan I Missile in the United States. The Intercontinental Ballistic missile Titan I on the launch pad. Its mission is to deliver the nuclear weapons to designated path on the earth surface. Direction and guidance is provided as the missile travels. Animation depicts: the velocity of the missile as it travels around globe and explains about the motor cutoff. Command Guidance system consists of 3 parts such as Radar, Missile borne equipment and the guidance computer. The missile borne equipment consists of receiver,decoder and transmitter.
The mechanism of air borne transmitter is explained in Command Guidance system for the Titan I Missile in the United States.
The operation of the Command Guidance system for the Titan I Missile in the United States. Animation depicts: the electronic loop ties the missile to the ground guidance equipment. Animation depicts the operation of the missile. The missile lifts up under booster power and turns in line with designated target area according to the program. Mechanism of the air borne transmitter which emits radio energy and radar antennas being explained. Change is measured by the code wheels on antenna shaft. Range and missile actual position is also determined. The information is fed into computer system. Actual data is collected and compared with the fed data. The deviations are then calculated. Pitch yaw,steering orders and address codes are sent to missile. The missile borne equipment decode and send back its transformed tracking signals. The booster is separated and motor is ignited. Motor shuts as the desired velocity is attained and the payload is separated. The velocity data is calculated using moving bar charts and the concept of smoothing time being explained. Features incorporated to protect external jamming of the Command Guidance system includes power,antenna pattern,frequency ,code protection and blanking of receiver.
The composition of the Titan I missile operational squadron in Command Guidance system in the United States.
Command Guidance system for the Titan I missile in the United States. The composition of the Titan I missile operational squadron which consists of : three extensive underground launch complexes which are composed of three missile launchers and two antenna silos for the guidance radars. Concrete doors which open before launch. Cylindrical elevator platform lifts up the antennas. The three uplocks locks the position of the antennas. The uninterrupted performance of the antennas is insured by the provision of stand by antennas. During the check out operation the missile borne guided equipment is connected with the missile test set. The test set issues commands,measures performance and check proper response. Animation depicts: the concept of handover technique in which any complex can guide its missile to the alternate complex. The acquisition path is explained using animation.
Crew operates push buttons and guidance computers at the control center of the Command Guidance System in the United States.
Activities at the control center of the Command Guidance System in the United States. Ballistic Missile Analyst,Missile Combat Crew Commander and Guidance Control Officer operates radar equipment and guidance computers in the operation room of the control center. Meteorological data is fed in computers. Missile Combat Crew commander at control panel. He controls the TV monitor,transmitter receiver and antenna position. He operates the push buttons to select target,to initiate power on and to lift the antenna. The countdown begins and the missile launches from a silo lift launch complex. Bomb damage assessment is printed. The radar recycle equipment is ready for another launch and another missile is launched.
Workers draw design on glass pitcher and cut design by steel wheel and carborundum dust at glass factory in the United States.
Cut glass making at a glass factory in the United States. A worker draws design on a glass pitcher. Other workers roughly cut design with a steel wheel and carborundum dust. The glass cutter used to smoothen the rough incisions. The workers complete the design with a stone wheel. The women workers make more delicate designs and do fine glass cutting. A worker polishes the glass after cutting is completed. Other workers cut design on bowl. The prepared glass treated to an acid bath to preserve its luster. Finally the glasses are washed.
