Content, Learning Outcome and Preconditions

Content

Based on the preknowledge of Fluidmechanics I/II the gheneral contexts of the fluidmechanics re-entry-able spacecrafts are explained. On the basis of resulting speeds and forces we can elaborate rules of thumbs for the airforces at the reentry. In addition we discuss also the status of the atmosphere in high altitudes. Then we present alto the detailled fluidmechanical and chemical processen in hot highspeed streams. The following subjects from the subject area re-entry-aerodynamics are treated:
- Elementary treatment of the re-entry procedere
- Some basics of gaskinetics and fluents with relaxation
- Procedre to calculate inviscid hypersound streaming around slim and bluff bodies: Newtonsche Theory, Newton-Busemannsche Theory, hypersonic similitude theory
- Structure of hypersonic streaming fields
- Configuration of re-entry missiles
- Aerodynamic heating and ablation
- Heat protection systems
- Hypersound test procedures

Learning Outcome

The students knows the following after the successfull passing of the Modul Reentry-Aerodynamics: (1) Knowledge of the basic context at the reentry, (2) Methods (Rule of thumbs) by means of them the aerothermodynamic strain on a re-entry body can be estimated. (3) the ability to describe the chemical phenomenas of the hot gas fluids in the near of missile surfaces, (4) to describe the different reentrykonfigurations with regard to fluid phenomena, (5) the ability, to estimate the heat transfer in the reentryarea quantitatively, (6) the knowledge of test procedures for high speed streams.

Preconditions

Fluidmechanics I and II, Thermodynamics, eventually heat- und mass transport would be good but not forcely prescribed.

Courses, Learning and Teaching Methods and Literature

Courses and Schedule

Learning and Teaching Methods

Lectures: Presenting teaching procedures

Media

Multimedial based frontal instruction

Literature

Lecture script, Lecture Slides, Anderson "Hypersonic and high-temperature gas dynamics"

Module Exam

Description of exams and course work

The examination performances consist of an oral exam where the contexts of the lecture should be presented in a conversation. The most important is not to learn out formulas by heart but to be able to explain physical processes.

Exam Repetition

The exam may be repeated at the end of the semester.
