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. NASA engineers have devised a test setup to safely lift and swing the test payload. Figure 1 shows the Gantry and highlights relevant areas.

Figure 1: The NASA Landing and Impact Research Facility with winch locations highlighted.

The test setup includes three thirty-foot-tall ground towers each paired with a winch rated to 30,000

lb. (30 klb.). Each winch is installed on a concrete slab and positioned behind the ground tower as pictured in Figure 2. The cable is routed through a sheave and roller guide at the top of the ground tower before connecting to the test article up to 96 feet away. Thus, these winches provide horizontal pullback capability at approximately 30 ft. height for a hanging test article. The tower locations are shown with respect to the gantry and highlighted in Figure 3; two ground towers are near the south foot of the Gantry Center Bent and one ground tower is on the east side of the gantry. These winches and their respective control panels will hereafter be referred to as

Pullback Winches. Each winch system includes a pullback winch, cable, ground tower, sheave, and roller guide and will be referred to as a Pullback System.

The planned test setup also 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 4 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.) lifting 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. Figure 2: Diagram of Ground

Towers with 30klb winches.

2.0 Objectives

The objectives of this work are to:

1. Prove that the Lifting Winch:

a. Is installed correctly.

b. Functions as intended up to 125% of rated load.

2. Prove that each Pullback Winch:

a. Is installed correctly.

b. Functions as intended up to rated load.

3. Train NASA Operators on use of all winch systems

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 provide inspection of the winch systems after they are installed at the Gantry.

The Contractor will NOT be responsible for installing the winch systems. The Contractor will perform routine winch setup functions such as setting the limit switches and auto tuning the Variable Frequency

Drive. NASA will provide an electrician to perform troubleshooting and modifications that the Contractor recommends.

The Contractor will then perform a functionality test of each winch system with up to but not surpassing 5% of the rated load. The contractor will provide clear procedures and documentation for each inspection and test that will be approved by NASA prior to performing any work onsite. Throughout inspection, setup, and functionality testing the contractor will explain operations and train NASA personnel on the operation of the winches. Completed procedure documentation, otherwise known as an

“As-Run” copy of procedures will be provided to NASA after the Contractor conducts the tests.

NASA will be conducting a proof load test with loads up to 125% of rated load for the Lifting

System and an operational load for the pullback systems. The Contractor will review the test procedures and provide feedback prior to the proof load tests. The Contractor will observe the proof load tests and provide supervision and guidance as NASA operates the systems.

NASA is responsible for the winch hardware that the Contractor is inspecting and operating.

NASA will provide the weight used for the functional tests as well as the rigging of all test equipment.
