Special Issue Information

Dear Colleagues,

The design of structural components for aeronautical and space applications is very challenging since it generally involves several physics fields such as fluid dynamics, heat transfer (convection, radiation, and conduction), elastoplasticity, creep, and so on, that can interact. Then, those physical problems can be coupled, in a weak or strong way, or uncoupled. In the past, several approaches have been developed with the aim of obtaining accurate solutions, but they are usually very expensive for problems that are strongly coupled. 

As such, this Special Issue is devoted to the study of numerical multiphysics analysis and the design of novel approaches able to minimize computation time while not losing accuracy. Particular emphasis can be given to the design of thrust chambers for liquid, hybrid, or solid rocket engines where a multiphysics approach is needed. In addition, works in which the physics involved in the problem are studied in the same numerical framework are welcome. Finally, numerical approaches to simplify the numerical model by means of surrogate and reduced-order models are strongly appreciated since they provide the possibility, for example, to minimize the weight of the component in a reasonable computation time.

The present work describes the development of a graphical environment to represent typical flight instruments on a computer screen. The instruments’ behavior is displayed according to information regarding the aircraft’s flight conditions. Some of the instruments represented in this work, such as the altimeter, the vertical speed indicator, the aircraft speed indicator, and the Mach indicator, use air pressure principles. The algorithms and routines developed for the screen display are created using the C++ programming language and compiled independently to be included as libraries to improve the software performance. The algorithms developed for this purpose also include the corresponding relationship between the physical variables, such as the speed and displacement, and the standard atmosphere to provide an equivalent value. These algorithms are successfully tested using data information to simulate three hypothetical flights, which are divided into maneuvers with the aircraft in a stopped position, running on the ground, taking off and flying away, including some changes in directions. Moreover, the routines for displaying the aircraft path with the instruments’ animation are also successfully tested by comparison. Finally, an approach analysis as a function of the step time (Δt) used for calculation of the aircraft displacement to evaluate the efficiency of the numerical method integrated in the simulator is also described. It is proved that the aircraft instrument representation is appropriate according to the input data of the analyzed flights, and an improvement in the calculation can be easily obtained, making it possible to represent any flight condition on the aircraft instruments.
