• Senior Design Project

Task Abstract:

The next spacesuit used on the moon will have a portable life support system (PLSS) that conditions breathing gas for the astronaut. It is necessary to detect and measure the flow rate of the gas. Today’s space suit can detect if there is gas flow, but does not measure the flow rate. A new device will be needed to both detect flow and measure the rate.

Task Objectives:

Students would design, analyze, build and test a low pressure drop prototype vent flow sensor assembly for a lunar PLSS.  The assembly will utilize a commercially available (delta-P) sensing device in an application-specific venture.  Alternate concepts can be considered.

Educator Comments:

The project activity will be given to students as part of their course work. It will help students to know the types of malfunction mechanism and their corresponding symptoms that machine is likely to incur. The student will understand the historical and related events that may have caused changes in machine condition. The project will enable students to present on machine condition in as solid engineering form as possible. They will be able to take prompt action based on the machine diagnosis.
