A quick question: What are the max G forces that occur during a shuttle launch? Is there a good document that talks to all the launch requirements for a payload...? Thanks, Erik

From memory, I belive that the shuttle is subjected to 2.5 - 3.0 G's during launch, and about 2.? during re-entry. I have the exact numbers at home in a book. I will have a look tonight and post them tomorrow. Andrew | |||||

The Web has a wealth of info. Try starting at http://shuttle.nasa.gov I would not be surprised if it eventually led to info about the requirements for payloads. Burns | |||||

Yup besides the raw static g-force to determine physical support of a payload, there are other requirements such as shock & vibration characteristics that the payload would have to survive. the shock & vibration have complex & multiple frequencies, which probably vary in amplitude and frequency depending on which coordinate (X,Y,Z) which also have to be considered for securing electronics etc. within the payload. I recall an old project over 10 years ago that I worked on where we were asked to meet certain MTBF (reliability) criteria. MTBF can be calculated for different kinds of environments. One of them was referred to as "rocket environment", the most harsh environment one can probably have when it comes to punishment given to electronics. Bob |
