Aerodynamics and Planetary Atmospheres
(S3, elective, 6 ECTS)
Learning Outcomes:After completion of the course, a student has general knowledge about aerodynamics and atmospheric physics, as well as specific knowledge that allows combining these scientific disciplines in order to understand and analyse aerodynamic phenomena characteristic for a satellite in upper atmosphere or spacecraft landing on surface of a planet.
Knowledge and Understanding:
Acquiring general knowledge about structure and variability of planetary atmospheres, specific knowledge of the characteristics of Solar system planets atmospheres, general knowledge in aerodynamics as well as specific knowledge about aerodynamic and thermodynamic phenomena characteristic for spacecraft atmospheric trajectories.
Applying Knowledge and Understanding:Students are trained to use different models of planetary atmospheres such as Mars-GRAM, Venus-GRAM, NRLMSISE-00, to define equations that describe aerodynamic and thermodynamic phenomena that occur along spacecraft atmospheric trajectories, as well as to conduct numerical analysis of flow around lifting and ballistic configurations.
PrerequisitesMathematics and Classical mechanics, initial courses.
ProgramTheoretical Flow classification and flow field modelling, singularities and discontinuities in flow field, airfoil and wing in transonic and supersonic flow field, hypersonic effects, characteristics of continuum, transitional and free-molecular flow regimes, aerothermodynamic phenomena, chemical and thermodynamic (non)equilibrium in flow field.
Origin of planetary atmospheres, stability and evolution mechanisms, atmospheric dynamics (waves, vortices, turbulence), local and global atmospheric phenomena, vertical and horizontal structure of atmospheres, seasonal, diurnal and altitude variations of atmospheric parameters, chemical composition, key processes influencing atmospheric composition, characteristics of the atmospheres of the Solar system planets and their models.
Description of how the course is conductedSee next point.
Description of the didactic methodsThe course is held entirely by interactive electronic presentations. Every class consists of theoretical introduction and practical implementation of the covered topics by using appropriate numerical tools implemented in Python libraries. Students conduct calculations and visualizations of the problems characteristic for the covered theoretical topics so they do not remain too abstract
Description of the evaluation methodsThe final exam is based on two independent types of learning assessment: a) Students are requested to solve Lambert’s problem, interplanetary and trans-lunar Hohman and bi-elliptic transfer and at least one orbital maneuver by using appropriate tools implemented in Python libraries. b) An oral exam whose objective is to verify that the students have achieved an adequate understanding of basic concepts in celestial mechanics and astrodynamics such as two and three-body problem, modeling of gravity field and non-gravitational perturbations.
