Pyrotechnic Shock Testing, Measurement, Analysis and Calibration Training

Introduction:

Pyrotechnic Shock Testing, Measurement, Analysis and Calibration Training Course Description

This is a three- day introduction Pyrotechnic Shock Testing, Measurement, Analysis and Calibration Training to the theoretical and practical aspects of high frequency shock testing, commonly called “pyroshock” or “pyrotechnic shock” testing.

The basic physics involved in pyroshock, including meaningful measurement and analysis of the environment, will be presented and discussed. The presentation encourages attendees (having varied structural dynamic backgrounds and experience) to contribute their personal experiences and observations, and thus to collaborate with the teaching staff and their fellow attendees. Their experience, if any, might range from the quantification of the flight environment to test simulation and/or qualification and flight acceptance of flight articles.

Duration:3 days

Skills Gained:

The objective of this course is to introduce the designer, technician and/or engineer to the phenomena of high intensity, short duration field and test laboratory transients and the possible deleterious effects on equipment.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
