Two tractor earth movers carrying metal siding sections to other side where F-4 Phantom revetments are set up. Workers install siding sections and metal pieces. A Thai worker directs the tractor earth mover.
Aerials of Ubon RTAF airfield and F-4 revetments under construction
Aerial views of Ubon Royal Thai Air Force Base including POL and general storage areas. Views of flight line , with half constructed revetments and completed revetments, some containing F-4 Phantom aircraft.
Nuclear reactors designed and developed to power spacecraft after numerous tests.
Los Alamos Atomic Energy Commission Scientific Laboratory in New Mexico and mountains in the background. Scientists work with diagrams of nuclear reactors. Different equipment and nuclear rocket designs. Prototype of Nuclear reactor is made. Technicians work with KIWI experimental reactors. Towers and buildings in desert. KIWI reactor is checked in nuclear assembly. Reactor is taken to the testing area on a special rail car. Man works at a remote station to control the car. Liquid hydrogen is pumped into the reactor on rail car from near by storage tanks. Reactor tested on test stand shows flaming torch. Reactor transported for disassembly and inspection on car by remote control. Men use remote control manipulators for inspection. Exhaust gas from other reactor on test stand. Men work on diagrams. Narrator discusses next step as the NERVA program (Nuclear Engine for Rocket Vehicle Applications), a combined government and private industry (Aerojet and Westinghouse) effort headed by the Space Nuclear Propulsion Office (SNPO). Animated nuclear thermal rocket shown with NERVA technology ( Nuclear Engine for Rocket Vehicle Application), given the letter designation NRX.
Animation of nuclear powered rocket engine system; Scientists at work in Atomic Energy Commission facility in the United States
Working of nuclear thermal rocket engine system in a NRX rocket, explained through animation. (The engine emerged from the NERVA program -- Nuclear Engine for Rocket Vehicle Applications -- a combined government and private industry (Aerojet and Westinghouse) effort headed by the Space Nuclear Propulsion Office (SNPO). Core of cylindrical nuclear reactor inside the rocket through which hydrogen gas passes. Hydrogen is expanded through the nozzle to provide thrust. Reactor works by fission of uranium 235. Neutron particles reflected back to the reactor. Rotating rods installed in reflectors around the reactor to control the heat generated. Reactors on test stand in testing area. Reactor transported on rail car. Scientists and technicians work with reactors in Atomic Energy Commission facility.
New developments in nuclear propulsion and test of flight engines.
Testing of flight engines of spacecraft. Sign of 'PHOEBUS IB' nuclear reactor. Phoebus IB reactor in testing area of Atomic Energy Commission facility at Los Alamos in New Mexico. Technicians work with NRX-A6 reactor. A recently developed new test stand and a nuclear engine carried by rail car. Test of engines in test area. Animation shows spacecraft in space.
