Radio frequency propagation to and from icbm's and irbm's( Book )

1 edition published in 1959 in English and held by 1 WorldCat member library worldwide

An analysis has been made of a large number of ICBM and IRBM instrumented launches to determine the causes of data 'drop outs'. Results of the analysis show effects produced by flame, antenna ionization, antenna pattern and pressure shock wave. Recommendations are included which will assist systems engineers to reduce the detrimental aspects of the effects encountered. These effects are applicable to all systems of all frequencies. Data includes radar, Azusa, telemetry and other equipment operating on frequencies from 200 megacycles to X-band. (Author)

Errors in arbitrary components of position and velocity vectors( Book )

1 edition published in 1957 in English and held by 1 WorldCat member library worldwide

Formulas are presented for obtaining the standard deviation in components of the position and velocity vectors relative to a coordinate system O' when a set of position and velocity components are known relative to a coordinate system O' assuming standard deviations in the components of vector r relative to O' are known. When the origins of O and O' coincide, the results can apply to rotated coordinate systems
Tensile Circumferential Stresses Created by the Unloading Mechanism of a Suddenly Punched Hole in a Stretched Elastic Plate( Book )

1 edition published in 1961 in English and held by 1 WorldCat member library worldwide

THE DYNAMIC STESSES CREAED IN A STRETCHED ELASIC PLATE, BY THE SDDEN PUNCHING OF A HOLE AT ITS CENTER ARE CONSIDERED. Complete information is presented on the tensile circumferential stesses generted by the unloading waves which are creaed during punching. It is shown that the maximm dynaic stress in the vicinity of the hole is considerably larger than it related stati value. It is pointed out that this will be important to the creation of a propagating crack. (Author)
A note on the conical pendulum analogy to rotary sloshing( Book )

1 edition published in 1957 in English and held by 1 WorldCat member library worldwide

In R-W Memo GM45,3-397, Revision 1, a model for the sloshing modes was proposed. The purpose of the present note is to call attention to certain features which lend credence to this model and to indicate the necessary modification in baffle damping theory
Communication by vibratory tactile stimuli for wescon symposium( Book )

1 edition published in 1956 in English and held by 1 WorldCat member library worldwide

This paper is concerned with an apparatus and method for communication whereby tactile vibratory stimuli replace or supplement the visual and auditory means, particularly in areas of communication where, 1) threshold levels of pain for other organs exist, such as hearing in an army tank, or 2) to relieve over-saturated sense organs, such as hearing or seeing in high speed aircraft, or 3) where the type of communication requires an 'attention demanding' quality such as would exist in accident prevention in moving vehicles - i. e., ships, aircraft, trains, etc., and 4) where a necessity exists for speeded communication. In particular, the proposed system could provide the deaf with a 'telephone'. The basic system for communicating through vibratory tactile stimuli consists of a single apparatus whereby the five fingers of the 'speaker' rest on sensitive vibration sending diaphragms, and correspondingly, the five fingers of the 'listener' rest on sensitive vibration receiving diaphragms. A duplicate reversed system allows the 'listener' to become the 'speaker'
MOTION OF CONICAL PENDULUM( Book )

1 edition published in 1957 in English and held by 1 WorldCat member library worldwide

The motion of a conical pendulum has been studied by means of an analog computer simulation. The pendulum was excited by motion of the attachment point due to the application of a sinusoidal forcing function. Also the pendulum was initially displaced in the plane perpendicular to the direction of the forcing function. A damping ratio of 3% to 5% was used in order to attain a steady state frequency response record in a reasonable amount of computing time. Equations of motion and other formulae are given. (Author)
DESIRABLE EXPERIMENTS ON SLOSH DAMPING( Book )

1 edition published in 1957 in English and held by 1 WorldCat member library worldwide

Approaches to the problem of slosh damping are examined. In general, the most promising line of attack is to measure accurately the ratio of actual to predicted logarithmic decrements (or their equivalents), under car ully controlled laboratory conditions. The hope is that observed values of this variable constant will vary gradually and according to recognizable trends. The following aspects of the problem are considered: spaced baffles, scale effect, AMPLITUDE EFFECTS, ROUGHNESS EFFECTS, AND YDROELASTIC EFFECTS. (Author)
The ramo-wooldridge corporation general research program, 1957. section e. magnetic digital techniques( Book )

1 edition published in 1958 in English and held by 1 WorldCat member library worldwide

A progress report is presented on the investigations of digital circuits using ferrite memory cores and thin films
On the determination of stresses and displacements for unsymmetrical deformation of shallow spherical shells( Book )

1 edition published in 1957 in English and held by 1 WorldCat member library worldwide

The report is concerned with problems of bending of thin, elastic, shallow spherical shells of uniform thickness. Explicit expressions are derived, in terms of stress function and axial displacement component, for radial and circumferential displacement components. It is shown that certain uni-valued portions of the solution for stress function and axial displacement components give rise to multi-valued expressions for radial and circumferential displacement components. A new type of solution of the differential equations is derived which is multi-valued insofar as the stress function is concerned but given uni-valued expressions for all quantities which should be uni-valued. It is shown that this type of solution is needed for the analysis of problems for which a resultant side force is acting along the edge of a symmetrical circular boundary of the shell. The nature and form of this side-force solution differs in important respects from the corresponding known solution for the case of a flat plate. No direct transition is possible from the shell solution to the corresponding flat-plate solution. As a specific application, a shell is considered which is supported at its outer edge and which has a small symmetrical rigid insert
The energy electron in a gas in an arbitrary electric field i( Book )

1 edition published in 1956 in English and held by 1 WorldCat member library worldwide

The average energy of electrons in a gas in an arbitrary electric field is determined from the time dependent Boltzman transport equation. The assumptions are: collision frequencies are dependent of energy and there are only elastic collisions. The solution is obtained for the case of a sinusoidally varying field and contrasted with a solution obtained on a more elementary level. (Author)
The effect of propellant energy and mass distribution on rocket propulsion efficiency( Book )

1 edition published in 1957 in English and held by 1 WorldCat member library worldwide

The effect of varying the exhaust gas velocity of a rocket so that the exhaust gases possess little or no kinetic energy in an earth observer's frame of reference is examined. Under certain boundary conditions an improvement in terminal velocity of 10 to 20% is obtained relative to a rocket with fixed exhaust velocity. Given a fixed budget of energy per unit payload mass, the optimum mass of working fluid into which to distribute this energy (for maximum burnout speed) is calculated as a function of gravitational field strength.

Commentaries on optimization of f constant thrust electrical propulsion systems( Book )

1 edition published in 1956 in English and held by 1 WorldCat member library worldwide

D.B. Langmuir has calculated the exhaust velocities that optimize the mass ratio, the time, and the velocity increment for various weight to power ratios of the power source. E. Stuhlinger has used a different optimization involving the initial acceleration. This note will attempt to clarify the relative merits of these two optimization schemes and two others that naturally evolve from the analysis

The isolation and correction of computer malfunctions( Book )

1 edition published in 1956 in English and held by 1 WorldCat member library worldwide

The isolation and correction of malfunctions in most electronic digital computer installations was carried out by engineers. As the number of installations grow, this task will gradually be taken over by technicians. In order to make the process of malfunction isolation efficient, it seems desirable to utilize as many training aids and as much specialized equipment as is practical. In addition, one should take advantage of all feasible schemes as alternatives in the process of isolating malfunctions. In this report various factors which influence the isolation process are considered and alternative schemes for isolating and correcting malfunctions are discussed. (Author)
Principles and applications of the gyroscope( Book )

1 edition published in 1956 in English and held by 1 WorldCat member library worldwide

An introductory survey of the gyroscope is provided, starting with relatively simple concepts and applications to missile technology and proceeding through to a few of the more involved characteristics of the device. In ballistic and other missiles, gyroscopes may contribute to two basic functions. One is control of the missile, and the other is possible inertial guidance of the missile. For a missile, the problem of control includes provision of the means for (i) minimizing the undesirable effects of wind, gusts, and other disturbances on the missile assembly and (ii) maintaining stability of missile when overriding guidance signals are introduced. The problem of guidance, on the other hand, is to provide means for generating the overriding signals that will enable the missile ultimately to hit the selected target
