Launch Vehicle & Spacecraft Environments Course 2 Days
Environmental forces, whether natural or induced, produce loading on the launch vehicle, spacecraft, satellite and payload. Early in the development of any space system, these loads must be estimated and incorporated into the design, analysis and test programs. Environmental specifications are the basis for test levels which are used to verify the design and workmanship of a spacecraft.
This course provides analysts and test engineers with the necessary background and tools to produce a set of environmental specifications and test levels for a launch vehicle / satellite / spacecraft program. Emphasis is on how to progress from the measurement or analytical estimation of the launch or on-orbit environment to a specification that can be incorporated into the spacecraft test verification program. Testing requirements and considerations for each type of environment are also addressed.
The seminar is also useful for managers and system engineers wishing to gain a good understanding of how spacecraft environments and resulting requirements creep can impact their program risk . A flash drive provided contains PDF files of the course slides and useful estimation spreadsheets. Hyperlinks are embedded in the course slides which link to the related reference material or to outside web resources.
Launch Vehicle & Spacecraft Acoustic Testing Course
One of the major design challenges for launch vehicle, spacecraft, satellite and payload development is addressing the structural response to acoustic loads coming from launch vehicle rocket motors and aerodynamic effects. Spacecraft and payloads can be damaged or suffer performance degradation due to these loads. This seminar is designed for engineers, test personnel and managers who want to improve their understanding of vibro-acoustic phenomena, testing techniques and prediction methods.
The emphasis of the course is on the logical flow though the measurement of the launch vehicle acoustic environment, estimation of test loads and test methods as well as post test analysis and documentation. Acoustic test facility design is also covered in detail. This seminar gives the attendee the tools to create an acoustic test program which results in a spacecraft system that is fully qualified and acceptance tested for flight. A flash memory drive is provided which contains PDF files of the course slides and useful estimation spreadsheets. Hyperlinks are embedded in the course slides which link to the related reference material or to outside web resources.
An integral part of the flight verification process for a spacecraft, satellite or payload is achieved through validation of the finite element model of the spacecraft structure subsystem. Modal survey testing is the method used to meet this requirement.
This seminar provides an in-depth look at modal survey testing of spacecraft systems and subsystems. Emphasis is on the practical aspects of test planning, execution, data analysis and post-test data processing. The techniques discussed provide the attendee with the necessary tools to produce a set of verified natural frequencies and mode shape vectors that represent the mass and stiffness of the spacecraft in the test configuration. A short modal test demonstration is also performed give the attendees a hands on feel for the technique.
