Project summary

The objective of the present project is the development of a perfect tool for designing supersonic aircraft and aerospace systems. This tool has to comprise:
- results of systematic experimental studies of the total and distributed characteristics of schematized models of flying vehicles in a wide range of Mach and Reynolds numbers. A set of schematized models should be as full as possible to represent the most frequent types of flows formed around full-scale objects;
- development of new models and methods of numerical simulation of characteristics of prototypes of aerospace vehicles in an appropriate range of velocities, implying various levels of approximation, both fast and inexpensive engineering methods for choosing the layout of the would-be vehicle and more complicated techniques based on the Euler and/or Navier-Stokes models;
- results of verification of the developed models and methods both for determining the integral characteristics of a vehicle and for typical local flows formed, for instance, in the region of joining surfaces, upon interference of inpidual elements, etc.;
- careful analysis and identification of applicability areas of methods and specific codes, and formation of a database including software of various levels, experimental data, and their comparison.

Thus, the proposed project is aimed at complex studies performed to have a better knowledge in the field of the flow around super- and hypersonic aircraft, to improve and develop high-quality methods of calculation, and to generate a specialized database containing both experimental and numerical data on aerodynamic characteristics.

The experimental studies of a set of schematized models will be carried out in trans- and supersonic wind tunnels T-112 based at the Central Aerohydrodynamic Institute (M = 0.6 - 1.2) and T-313 based at the Institute of Theoretical and Applied Mechanics of Siberian Branch of the Russian Academy of Sciences (M = 2 - 6). Numerical models and methods will be developed on supercomputers with parallel architecture of the Keldysh Institute of Applied Mathematics.

The obtained results of numerical and physical modeling will be compared, analyzed, and united into a specialized database.

The project implies the use of the effort of scientists who have a large experience in development of military aviation and space vehicles. Thus, the execution of the present project will allow one to develop a tool for creating super-and hypersonic flying vehicles of higher aerodynamic quality with a lower amount of fuel spent for the same purpose, i.e., vehicles that satisfy the demands of environmental protection.

Role of foreign collaborators. The idea of the present series of experimental and computational works was initiated by ESA/ESTEC and "Aerospatiale" (France) who will take an active part in choosing the model configurations and discussing the results obtained.
