Advanced Suit Laboratory Support Sample Task Order #2 Advanced Space Suit Pressure Garment Laboratory Support for a Month

The Task Order (TO) addresses the standard laboratory support activities. As a sample TO, the scope of this example is limited to a month. Assume that only 1 suited run occurs on a test day.

1. Perform 4 pressurized, manned space suit tests in the laboratory environment in a month

a. Includes test preparation and post-test processing

b. Examples of ‘laboratory environments’ include the Advanced Suit Lab and the Anthropometry and Biomechanics facility

c. Assume 3 tests are performed with controlled hardware under Test Preparation Sheets with Quality involvement, and 1 test is performed with uncontrolled hardware

d. Assume one of the controlled hardware tests is a fit check

i. Includes verification of subject anthropometric dimension using an anthropometer, calipers and measuring tape and anthropometric landmarks

ii. Requires awareness of sizing variability from previous fit checks with people of similar dimensions and hardware dimensions and sizing features in order to select alternate hardware components to have available at the fit check

iii. During the fit check, provide inputs regarding acceptability of fit and alternate sizing configurations to improve fit

2. Performed 2 pressurized, manned space suit tests in a specialized test environment in a month

a. Includes test preparation and post-test processing

b. Examples of ‘specialized test environments’ suit tests (Neutral Buoyancy Laboratory (NBL), Active Reduced Gravity Offload System (ARGOS), vacuum chamber, thermal chamber, thermal/vacuum chamber, or analog test site e.g. the JSC simulated Moon/Mars field)

c. Test preparation includes collaboration and integration with the specialized test facility in order to:

i. Meet physical hardware integration interfaces

ii. Comply with the specialized test facilities specific safety, documentation and procedural requirements

3. Participate in new test planning and preparation

a. Activities may include: meetings with test customers; review of test documentation (test plan, test procedures, hazard analysis, test readiness review presentation, etc.); visit to proposed test area to assess test layout, safety considerations, access to transportation of suit and suit test ground support equipment; discussions of the impact of unique test requirements; discussion of test logistics and scheduling; discussions regarding unique test set-up hardware needs and attainment/fabrication plans

b. Determine if unique suit test ground support equipment is required and participate in obtaining or fabrication of the unique equipment

i. This includes participation in the requirements development for the unique ground support equipment

c. Participate in unsuited and suited engineering dry runs in order to finalize the test plan and procedures and to check out unique test hardware and/or procedures

4. Space Suit and Laboratory Equipment Maintenance

a. Perform standard maintenance on 3 pieces of space suit hardware

i. Assume a pair of gloves; a back pressure regulator; a rear-entry composite hard upper torso

ii. Perform a unique repair on a rolling convolute shoulder

b. Perform standard maintenance on a space suit ground support equipment breathing air supply

5. Fabrication and assembly efforts NOTE: The Advanced Suit Laboratory primary machines include milling machines, lathes, band saws, and drill presses (including radial) in addition to a wide variety of hand tools.

a. Fabrication and Assembly activities

i. Assume production of 5 simple components, 2 medium complexity components, and 1 complicated component

1. Examples of a simple component: aluminum plate to mount on the rear-entry upper torso hatch for the mounting for test support components (flat aluminum plate that screw mounts to the hatch); modify standard fasteners to custom dimension (usually cut to length)

2. Example of a medium complexity component: custom space suit axial restraint bracket pins (small, precise, machining on a cylinder); modification of space suit axial brackets (curved, precise, off-set screw holes, screw hole alignment on suit hardware)

3. Example of a complicated component: microphone mounts for the integrate communication system (small, precise, use of computer numerical control (CNC)) ; retro-fit shaft for the Z-1 prototype hatch latch for actuation from the backside of the suit (interfaces with several components includes gears and detents)

b. Assembly of a structural and leakage and test rig

i. Requires the ability to read and assemble to a drawing in addition to an understanding of the function of the rig

1. Includes translation of the schematic to the physical hardware configuration

a. tube layout and line runs are under the purview of the assembler

ii. Includes pre-use functional testing
