A route to learning supersonic aerodynamics in atmospheric flights for engineering students based on a revision of Bloom’s taxonomy

According to Deloitte, the global aerospace industry in 2018 experienced a solid year with the demand of passengers and the strengthening of global military spending that continues to increase. Furthermore, it is expected to continue its growth trajectory in 2019 and the following years, led by the growing production of commercial aircraft and strong defense spending. The growth of aircraft production requires the designs to be supported by the knowledge and experience of qualified personnel. In the case of aerodynamic performance, it is evaluated according to the speed range considering incompressible or compressible flow for subsonic and supersonic speeds, respectively. Based on a revision of Bloom´s taxonomy this article proposes a route to learning supersonic aerodynamics for engineering students, considering and discussing the basic literature and technology used in this area of knowledge. The present work is divided into seven parts, beginning with the introduction which includes the main Fundamental concepts of the supersonic systems. The second part deals with Supersonic Aerodynamics Theory, relevant in this learning route; subsequently, the third and fourth part display a brief description of the Experimental supersonic aerodynamics and Computational Fluid Dynamics - CFD is made. Finally, is approached the Bloom´s taxonomy and a revision and is proposed a route to learn supersonic aerodynamics designed for engineering students.

Identification of identifiable parameters affecting aerodynamic performance

The developed scientific works are directly related to solving the problems of identifying multi-parameter objects. The proposed algorithm is effectively implemented on a computer, which is confirmed by calculations of problems of supersonic aerodynamics

ON THIN OR SLENDER BODIES

This is a review of thin-body and slender-body theories, with indications of some new applications. Topics discussed include bodies with near-constant surface pressure, subsonic and supersonic aerodynamics, ship hydrodynamics, slender bodies in Stokes flow, slender footings in elastic media, and slender moonpools. Mathematical features of the thin- and slender-body approximations are also discussed, especially nonlocal convolution terms modelling three-dimensionality in the otherwise two-dimensional near field, end effects, and the role of the logarithm of the slenderness ratio. This review was presented by the first author as the IMA Lighthill Memorial Lecture at the British Applied Mathematics Colloquium (BAMC) 2004.

Effect of Elevated Temperature on the Flutter Characteristics of FGM Panel

This paper investigates the stability issues of functionally graded material (FGM) panels subjected simultaneously to both aerodynamic and thermal loads. Finite Element Method is employed to model the panel structures and the supersonic aerodynamics is calculated by the first-order piston theory. The critical buckling temperature elevation of the panels is at first predicted. The nonlinear static analysis of the panels is then implemented at certain interval of temperature elevation before buckling onset to obtain structural stiffness matrix. The flutter speed of the panels with updated stiffness matrix corresponding to a certain temperature elevation is estimated. The results show that the FGM panels can offer beneficial effects, especially prevention from buckling. However, if FGM panels integrated with TPS are to be applied on supersonic vehicles, one should pay more attention to the boundary conditions to guarantee the dynamic stability.
