The investigation was conducted at Mach numbers from 0.60 to 1.40 and jet total-pressure ratios from 3 to 20. Three different boattails were tested: an 8-degree conical afterbody, a 16degree circular-arc afterbody, and a third afterbody having a linear area variation with length. A cylindrical afterbody also was tested for comparison purposes. Extending from these bodies were four circular jet nozzles with a design Mach number of 2.5 which were spaced symmetrically about the body center line. The 8-degree conical afterbody provided the highest net thrust efficiency factors when the nozzle exits were at the optimum longitudinal location. The other afterbodies in order of decreasing performance were the 16-degree circular-arc, the straight-linearea-distribution, and the cylindrical. (Author). |

A digital-computer simulation was made of the midcourse (or ascent) phase of a rendezvous between a ferry vehicle and a space station. The simulation involved a closed-loop guidance system in which both the relative position and relative velocity between ferry and station are measured (by simulated radar) and the relative-velocity corrections required to null the miss distance computed and applied. The results are used to study the effectiveness of the guidance equations and the effects of errors in launch conditions and errors in the navigation (radar) data. Trajectories are presented for rendezvous with a space station in a circular orbit and in an elliptic orbit. (Author). |

Various procedures are given for writing explicit difference approximations to the one-dimensional lagrangian hydrodynamics equations. Computational comparisons are made among systems of equations with timing modifications. These comparisons lead to experimentally superior differencing forms. Stability analyses of these difference forms show the reasons for the superiority of one form over another. Of greater importance, the stability criteria obtained show the function of an artificially introduced diffusion term required in the treatment here given to shocks. The stability criterion in each case involves the familiar Courant condition and a term which corresponds to the stability criterion of the diffusion equation. Upper limits to the magnitude of the coefficient of the diffusion term are established as a function of Courant number. While lower limits are also indicated, they require modification when shocks are involved. Alternate differencing schemes are considered in which the previously-used total energy calculation is replaced by an internal energy calculation. It is shown that care must be taken that the kinetic and internal energies are expressible in terms of local quantities. That is, in addition to the equations being conservative in a gross sense, they must also be locally conservative. This is necessary in order that the energy condition of the Rankine-Hugoniot equations be satisfied when shocks arise. Finally discussion is given to errors resulting from the replacement of shocks by a shock layer, that is, errors connected with the artificially inserted diffusion term. These errors are manifested in distortions of profiles at material discontinuities through which shocks have passed and in rarefactions associated with such occurrences. The errors in turn effect stability in the vicinity of the material discontinuities. contract W-7405-Eng. 36 with the U.S. Atomic Energy Commission. |
