MISSILE SILO CONVERSION FOR EVALUATION OF HIGH ENERGY RATE IMPACTION.
Abstract
One of the limitations in high energy rate forging has been the energy capacity of equipment. As a means of demonstrating a potential system for increasing energy capability, a machine to utilize the basic components of an Atlas-F missile silo to provide a high energy rate impaction machine with a nominal capacity of two million ft-lb was designed, built, and tested. The machine components include a platen made up of approximately 100 tons of excess flywheels, a 10-ton ram and a hydraulic shock absorbing system to stop the platen after impact. Four test shots were made with the machine; two on 9-1/2 in. diameter cans containing alumina powder, one on a 24 in. diameter titanium cup, and one on a 26-in. by 29-in. wing hinge pivot lug configuration. The maximum energy utilized was 2,930,000 ft-lb. This was achieved with a 10-ton ram, 3,800 pounds of tooling on the ram and a 123-ft drop. Energy input to the work piece was in the range of 75% of the energy in the ram at the time of impact. The maximum force on the work piece was at least 20,000 tons. Test forgings were imperfect but improvements in processing could be made to provide more nearly perfect forgings. Capability of the machine for compacting large volumes of ceramic powder and forging titanium pieces with large plan view areas was demonstrated. (Author)
