1.0 Background

The National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC) is preparing to conduct a Moon Landing Test (MLT) under the Human Landing Systems (HLS) Program.

The MLT campaign will involve a series of impact dynamics tests of a mock lunar lander. These tests will be conducted at LaRC’s Landing and Impact Research (LandIR) Facility, also known as and hereafter referred to as the Gantry. At the west end of the facility is the Hydro-Impact Basin (HIB) with approximately 1 million gallons of water available for use if needed for water bag weights. Figure 1 shows the Gantry and highlights relevant areas.

Figure 1: The NASA Landing and Impact Research Facility with upper platform location highlighted.

The planned test setup includes a single winch rated to 60,000 lb. (60 klb.) installed at the top of the center bent of the gantry highlighted in Figure 1, at a height of approximately 240 feet. The cable is pulled out horizontally before running through a sheave off the platform. The cable then runs through a snatch block and is fed back up through the platform via a second sheave and finally anchored to the upper platform. Figure 2 shows a diagram of the lifting system. This winch provides the main lifting capability for the test article and in this setup has a 120,000 lb. (120 klb.) working load limit. This winch and its control panel will hereafter be referred to as the Lifting Winch. The entire system which includes the lifting winch, cable, double sheave, snatch block, and anchor will be referred to as the Lifting System.

The Snatch Block has a swivel hook with safety latch for connecting the load.

The Swing System is a static system consisting of a plasma rope fixed to the Gantry via a custom spindle. The Swing System is designed to hold the weight of the test article and allows for side-to-side movement of the test article unlike the Lifting System which is designed for vertical lifting with minimal angling. There is a davit crane rated to 3,000lb positioned to assist with attaching hardware to the Swing Cable. There is otherwise no inherent lifting capability at the Swing Cable, so any proof load will need to

be lifted and attached to the Swing Cable. The Swing Cable is a 120ft. synthetic rope (Cortland Plasma 12x12) with 2-3/4” diameter and spliced eye ends.

2.0 Objectives

The objectives of this work are to:

1. Prove that the Lifting System can be loaded to 125% of its load rating in the installed configuration.

2. Prove that the Swing System can be loaded to 100% of its load rating in the installed configuration.

NASA will be using the deliverables from this work to close out project requirements. These requirements are noted in this document for reference only.

3.0 Scope

The Contractor will test the Lifting System incrementally up to 125% of the maximum rated load.

NASA personnel will operate the Lifting Winch in accordance with the procedure written by the Contractor. NASA personnel will perform an operational check on the Lifting System after the proof load test. The Contractor will then incrementally load the Swing System up to 100% of the operational load.

The Contractor will be responsible for sourcing the appropriate weights to test each system according to the requirements. The Contractor will provide clear procedures and documentation for each test that will be approved by NASA prior to performing any tests. Completed procedure documentation, otherwise known as an “As-Run” copy of procedures will be provided to NASA after the Contractor conducts the tests.
