Sep 8, 2021 | Sources Sought

This is a Request for information (RFI) for written information only.  This is not a solicitation announcement for proposals and no contract will be awarded as a result of this announcement.

The Naval Air Warfare Center, Aircraft Division, Lakehurst NJ (NAWCADLKE) requires Acceptance Testing to validate that the Rescue Hoist Test Stand is properly constructed and performs all aspects of its intended function within its operation requirements for testing the Rescue Hoist Assembly.

The RHTS is functioned to simulate the aircraft operating environment that provides the capability to perform end-to-end test of the Rescue Hoist Assembly as well as to adjust and to fault isolate failed components on the Rescue Hoist as deems repairable and replaceable. The end-to-end test includes dynamic load testing of the rescue hoist up to 600 lbs. and static testing up to 1850 lbs.  The RHTS operates on 480 VAC, 3-Ø, 60 Hz @ 31.2 Amp supplied by the facility. The Operator Control Station (OCS) known as the all-in-one controller contains a Programmable Logic Controller (PLC) using ladder logic program written in Cscape software from Horner Automation that uses inputs from the operator (power push buttons), two load cells, an encoder, a turbine flowmeter, pressure transducers, and the limit switches in the rescue hoist and produces output signals that control the hydraulic and electrical systems via various relays/contactors to operate the test stand for testing the Rescue Hoist Assembly. In addition, the Cscape program provides two Proportional Integral Derivative (PID) elements with auto-tuning function which can be manipulated by the ladder logic program that can be configured from the PID element configuration screen. The PID control function is being implemented to stabilize the system in the process as disruption is encountered during operation.
