Course Description:     Senior students perform a team-based spacecraft design, requiring application of the education and skills developed in the aerospace curriculum. Components include analysis methods for preliminary design, development of an initial spacecraft and mission concept, and development of a complete numerical model of the mission, culminating in oral and written reports by the teams.

Offered:    Fall and Spring

Pre-requisite:    None

Co-requisite:    None

Required:    Either/Or Option with AAE 45100, Sem 8

Topics:

  1. Analysis Methods to be used for Preliminary Spacecraft Design
    Loads, mass distribution, and center of gravity. Simplified estimation of structural weight. Orbital mechanics above a spherical rotating earth. Newtonian aerodynamics. Skin friction and heat transfer using simplified correlations. Static stability. Lumped heat-capacity model for thermal protection system. Selection among existing propulsion systems. Boost trajectory analysis. Space communications. Instrumentation. Use and adaptation of existing software
  2. Development of an Initial Spacecraft and Mission Concept
    Selection is based on historical background and engineering judgment, plus qualitative studies of vehicle requirements, mission goals, and possible vehicle concepts. Fundamentals of project management. The spacecraft and mission concept will include a number of free parameters, such as vehicle length, slenderness, mass, tank position, orbit selection, power system, attitude precision and so on. First formal report
  3. Development of a Numerical Model for the Vehicle Concept
    Based on sections 1 and 2, a numerical model must be coded and checked. The concept in section 2 must be sufficiently specific that it is feasible to develop this model in the time available. Validation of model for second formal report
  4. Configure Vehicle using Trade Studies based on the Simulations
    Quantitative trade studies performed using the model. Traceability of design parameters to mission requirements. Risk assessment and cost estimation. Selection of final configuration. Reporting of vehicle characteristics and performance. Final report.
