It is shown that in the plane of reinforcing of the composite the maximum thermal deformations occur in a direction at 45/spl deg/ to the base of the fabric of the filler and with an increase in heating rate is a significant reduction in its amplitude. The residual relative thermal deformation of the heat-protective material tested according to the program of descent from a trajectory may reach 2% and more. The calculation of thermal stresses occurring in a layer of thermal protection during a spacecraft reentry in dense atmosphere is done using a method of the theory of elasticity with allowance made for physico-mechanical characteristics obtained for conditions simulating the actual ones. The tangential stresses, /spl tau//sub z/spl theta// and /spl tau//sub rz/, at the juncture of the frontal shield with the side surface and also at 1/5th of the length of the reentry vehicle at its both ends, at a depth of 3-3, 5 mm from the outer surface are shown to be the most dangerous for the strength of the heat-protective coating.","PeriodicalId":122871,"journal":{"name":"ICIASF'97 Record.

Two specially designed modifications of direct method of variational tasks solution are disclosed-one (for short-term trajectories with strong restrictions on control functions) based on 5th-7th power polynomials optimal trajectory approximation, the second (for long-term flight on a route trajectories) based on spline approximation. Both from a conditional arch argument, with obligatory satisfaction of phase coordinates and control boundary conditions (a priori) and all limitations (in the process of optimization).

This can only be achieved in full scale combustion chambers by adopting advanced monitoring and control techniques based on non-intrusive combustion diagnostics. This paper reports the development, implementation and test of a laboratory flame 3D temperature sensor which allows for the tomographic reconstruction of the temperature field, based on the flame radiation emitted at /spl lambda/=800 nm and /spl lambda/=900 nm. The current work aims to contribute to overcome the difficulties on the application of tomographic techniques to large scale combustion systems by adopting new strategies for flame data collection and processing. In this paper the various stages for the development of a flame tomographic sensor are presented, namely: a review of the physical concepts involved, together with the selection, development, optimisation and implementation of tomographic algorithms. The design and assembly of the laboratory rig, the experimental procedure, and the evaluation of the results obtained, are also discussed.","PeriodicalId":122871,"journal":{"name":"ICIASF'97 Record.

Many techniques already exist which allow for nonintrusive measurements of pressure, temperature and density; several of which are two-dimensional by design. Holography and holographic interferometry are well established techniques; however, for the most part they provide qualitative data. A computer program for achieving quantitative two-dimensional or axis-symmetric density maps using a phase-shifted holographic interferometer is currently being developed. Several phase unwrapping and data reduction methods were investigated in an effort to produce a computer program capable of correctly analyzing a flow field. Several test holographic interferograms of a candle flame and a heat gun, made in a laboratory setting were used to validate various aspects of the software algorithms. A discussion of the algorithms investigated and the determination of which algorithm best analyzes the flowfield structures will be presented.","PeriodicalId":122871,"journal":{"name":"ICIASF'97 Record.
