Experimental Study of Upsetting and Die Forging with Controlled Impact
The results from experimental research of deformation by upsetting and die forging of lead specimens wit controlled impact are presented. Laboratory setup for conducting the investigations, which uses cold rocket engine operated with compressed air, is described. The results show that when using controlled impact is achieving greater plastic deformation and consumes less impact energy than at ordinary impact deformation process.

Industrial rocket engine and its application for propelling of forging hammers
Abstract The design of the first industrial rocket engine (IRE) and an IRE propelled forge hammer are described. The new technological capabilities of the IRE propelled hammers like a “sticking impact”, dynamic regulation of the deformation process parameters, and minimization of the manufacturing drain are discussed. The conditions for the “sticking impact“ and for the “ideal hammer” are given.

and plutonium as fuel and hydrogen and ammonia as propellent (in all cases, graphite is the moderator and the propellant temperature is 2000 C). The problem of soft landing instruments on the moon is also treated. The third category deals with other space-flight problems—re-entry heating, recovery of earth satellites, cabin conditioning equipment for manned space flight, and instrumentation available for conducting scientific experiments using unmanned earth satellites. A large number of topics related to space-flight technology are treated very lightly or omitted entirely—for example, trajectories for orbital insertion or for interplanetary probes, automatic control and guidance, space orientation subsystems, electrical propulsion, testing and reliability, data processing, and so on. This is doubtless because the book was not intended to be an engineering text but rather to provide a general background on the basis of which the proper level for British astronautical effort might be discussed, a purpose to which it is very well suited. Most American readers will be more interested in the papers of the second and third categories than those of the first. In general, the engineering subjects treated in the volume are handled in a competent and readable fashion. Accordingly, the book can be recommended either as an introduction to or as a review of these subjects.
