FRAG requirements for control of fatigue testing : second issue by R Cook( Book )

4 editions published between 1989 and 1991 in English and held by 5 WorldCat member libraries worldwide

This Memorandum describes the findings of a working party formed by the Fatigue Research Advisory Group (FRAG). It defines the accuracy requirements of load application, calibration requirements and test data that must be recorded. Various methods of control are described which may be used to achieve the testing accuracy requirements. The requirements are applicable to both fatigue testing machines and single actuator test rigs, used to generate materials data and to test simple coupons. The requirements are periodically reviewed; this Memorandum is issued as part of the review procedure and supersedes the first issue Mat/Str 1130 issued in May 1989
Heat generating compositions for thermal batteries by V. N Sheptunov( Book )

2 editions published in 1991 in English and held by 5 WorldCat member libraries worldwide

Thermal batteries are widely used as independent current sources with long storage life and the ability to operate over a wide ambient temperature range of -54 to +71 C.A number of pyrotechnic materials may as a rule be used as sources of thermal energy to provide ionic conduction in a molten electrolyte and to maintain the working temperature of the battery during the discharge of the electrochemical elements (EKhE). The reliability of ignition of the heat generating elements (NE) is a fundamental problem which requires a solution before they may be considered for use in thermal batteries. In this connection it is reckoned that a fundamental item in the technical specification of a thermal battery is the activation time, ie the time from the moment of application of the electrical impulse to ignite the NE to the moment of achieving maximum power from the EKhE

The stereoscopic geometry of the remote sensing optical mapping instrument by N Wells( Book )

3 editions published in 1990 in English and held by 5 WorldCat member libraries worldwide

This Report examines the geometrical principles of stereoscopic remote sensing upon which the proposed Optical Mapping Instrument system is based. Consideration is given to the cartographic potential of the system in terms of constraints that arise from the viewing geometry, and conclusions are reached concerning the required accuracy and stability of the instrument. The proposed Optical Mapping Instrument (OMI) is a space-based remote-sensing payload designed to produce high-resolution image data from which cartographic information can be derived. An outline specification of the OMI is given in Appendix A. The instrument has the capability of generating a stereoscopic pair of images of a given region, taken from different positions in a sun- synchronous, near-polar orbit. Northings and Eastings (or planimetric data) can be inferred from a single image, however the relative height of the terrain (or topographic data) is only derivable from a stereoscopic pair of images of the desired region. As examined in the present report, the parallax, ie the apparent relative displacement of features in the two images that results from a change in viewing position, is used to calculate the relative height of any point in the scene. The main purpose of the report is therefore to study the geometry associated with this stereo-viewing technique. The geometry has a direct bearing on the cartographic potential of the system since the desired system performance is governed by requirements arising from various geometrical constraints. Section 3 of this Report introduces the relationship between mapping potential and viewing geometry. (KR)
Geopotential harmonics of order 15 and 30 from analysis of 50 orbit determinations of 1967-102B by D. M Walker( Book )

2 editions published in 1990 in English and held by 4 WorldCat member libraries worldwide

The orbital parameters of the satellites 1967-102B, Cosmos 184 rocket, have been determined at 50 epochs from some 3900 observations. For 21 of these determinations, Hewitt camera observations were available. During the time of the orbit determinations the satellite passed through 15th-order resonance. The variations in inclination and eccentricity have been analyzed to obtain six lumped 15th-order geopotential harmonics, with accuracies equivalent to between 0.2 and 3.3 cm in geoid height and four lumped 30th-order geopotential harmonics, with accuracies better than 1 cm in geoid height. The lumped harmonics obtained in this Report have been compared with those from the GEM 10B and 10C models and with those from GRIM3-L1 and the RAPP 1981 models. A comparison has also been made with the lumped harmonics obtained from a new PGS- 3337 model published by NASA, and the agreement with this model is very good.

Temperature control in thermal batteries( Book )

2 editions published in 1991 in English and held by 4 WorldCat member libraries worldwide

Temperature control in thermal batteries, whose operation depends on the melting of an electrolyte by means of pyrotechnic heating, is provided in order to maintain the temperature of the electrochemical elements (EKhE) within the required working range of 350-700 C. Existing methods of temperature control in thermal batteries are classified as active and passive. Passive temperature control provides thermal stability of the EKhE mass by placing around it layers of thermal insulating material. Active temperature control provides for the introduction of heat into the element block from one or another source arranged inside the battery, and for it to be effective over the working period. Thermal insulating layers are commonly achieved by means of materials of low heat conduction which must exhibit chemical stability against molten salts, withstand short-term temperature rise, and be mechanically stable against shock and centrifugal loads. In thermal batteries tough, resilient thermal insulators are employed. Kaolin-based fabric, fibreglass and asbestos are used in such materials. The element block may be wrapped in them; it is also possible to have alternate layers of various materials, for example, ceramic, glass fibre or mica
Evolution of a voltage-time model of thermal batteries by J Knight( Book )

2 editions published in 1991 in English and held by 4 WorldCat member libraries worldwide

A temperature time model of thermal batteries has almost been completed and validated against experimental data. This Memorandum first summarises early attempts to integrate a voltage-time model into this, taking advantage of the instantaneous predictions of temperature, thermodynamic potentials, and internal resistance which the thermal model provides. It then describes how recent refinements of the voltage-time model have led to improved simulation of the discharges of a wide range of sizes and types of thermal battery under an equally wide range of test conditions. The semi-empirical approach adopted has been to provide a universally-applicable framework based on logical concepts to cover various effects such as polarisation etc, but with adjustable numerical parameters. It is shown that a moderately good simulation may be obtained for the majority of available discharge curves, using this one set of equations and without altering parameter values. Further improvements can be obtained when parameter values are optimised for one particular type of battery. Comparisons of model simulations against a body of experimental data have pinpointed remaining discrepancies which will guide further refinement efforts
Integration of flight management and air traffic management systems by Garteur Action Group FM(Ag)03( Book )

2 editions published in 1990 in English and held by 4 WorldCat member libraries worldwide

GARTEUR Action Group FM(AG) 03 was set up in late 1984 to consider how airborne Flight Management Systems and the equivalent ground based Air Traffic Management System could work together to form a genuine Integrated ATM System. A particular problem was how best to utilise the airborne precision 4 dimensional navigation capability that was moving from the experimental realm to airline adoption. The resulting concept of a computer based strategic ATM system utilising 4D trajectories with defined tolerances has become known as the GARTEUR 4D Tubes in Space Concept. These concepts were developed through a series of publications and have proved to be very influential in shaping the thinking of groups such as the ICAO FANS Committee and the PHARE European experimental ATM programme. This final report describes the Group's activities and concludes with recommendations for the work of a successor group
Tracking in uncertain environments by D. J Salmond( Book )

2 editions published in 1989 in English and held by 4 WorldCat member libraries worldwide

A tracking filter is an algorithm for estimating the state (such as position and velocity) of an object from measurements of a sensor such as a radar. This study concerns the problem of tracking a target when the origin of the sensor measurements is uncertain. The full Bayesian solution to this type of problem gives rise to Gaussian mixture distributions, which are composed of an ever increasing number of components. To implement such a tracking filter, this growth of components must be controlled by approximating the mixture distribution. Two algorithms have been developed for approximating Gaussian mixture distributions. These techniques attempt to minimize the number of mixture components without modifying the 'structure' of the distribution beyond a specified limit. Also the final approximation is itself a Gaussian mixture. The performance of the algorithms has been assessed by simulation for the problem of tracking a single target in the presence of uniformly distributed false measurements. This assessment indicates the significant range of problem parameters where the new algorithms give a substantial performance improvement over the well known Probabilistic Data Association Filter (which approximates the mixtures by a single Gaussian component). The tracking example is extended in the second part of this study to show how the Bayesian approach may be applied to more complex uncertain tracking problems, including that of fusing data from several independent sources.

The initial buckling of a long and slightly bowed panel under combined shear and normal pressure by E. H Brown( Book )

1 edition published in 1953 in English and held by 4 WorldCat member libraries worldwide

"American experimental work has suggested that the resistance to buckling of wing skin panels under compression or shear loads is improved by aerodynamic section. A complete theoretical analysis of this problem is very difficult, because compression load necessarily involves the consideration of post-buckling behaviour. An approach is made in this report by considering the restricted problem of the initial buckling of a long, thin and slightly bowed panel under combined shear and normal pressure."--Author's summary
Airfield lighting : future trends by A. J Smith( Book )

1 edition published in 1988 in English and held by 4 WorldCat member libraries worldwide

Airfield lighting is an essential part of the aviation business. Like the aircraft that they support, airfield lighting systems have over the years increased in size and sophistication and the financial and engineering investment in the equipment is a significant factor in the cost of an airfield. It is inconceivable even with a further expansion of the use of avionics that the need for visual signalling will ever by eliminated. However, the time is opportune to review the efficiency of present systems and predict possible future trends. This Memorandum takes a critical look at approach and runway lighting for fixed wing precision approaches including maintenance standards and considers the needs for visual aids to support helicopter operations. The possible applications of new technologies to enhance surface movement, guidance and control systems is also reviewed. Keywords: Great Britain; Air traffic control systems; Runways. (KT)
Application of S1BYL2 to the AGARD WG18 compressor test cases by W Calvert( Book )

2 editions published in 1991 in English and held by 3 WorldCat member libraries worldwide

S1BYL2 is an inviscid-viscous blade-to-blade method for calculating the detailed aerodynamics and overall performance of compressor blades. It may be applied either on its own to predict the flow for individual blade sections, such as the mid span of a linear cascade, or in conjunction with a throughflow calculation to predict the performance of a complete axial compressor
The effect of a splitter plate on the symmetry of separated flow around a delta wing of low aspect ratio by S. B Zakharov( Book )

2 editions published in 1990 in English and held by 3 WorldCat member libraries worldwide

Using the approximation of the theory of slender bodies an investigation is made into the non-uniqueness of solutions for separated flow around a delta wing of low aspect ratio in the presence of a delta splitter plate on the upper surface of the wing and in the plane of symmetry. An improved method of formulation offers increased accuracy, when applied to the solution of similarity problems in vortex sheets. Some substantially asymmetrical solutions to the problem of separated flow around the wing under symmetrical conditions of flow are obtained, as well as some symmetrical ones. Considerable attention is paid to an explanation of the nature of the bifurcations in solutions and to a qualitative description of hysteresis in the aerodynamic characteristics as a result of a quasistationary change in angle of attack and yaw angle by the use of a simplified mathematical model of a vortex sheet 'vortex and cut'
