69 -- LANDING CRAFT AIR CUSHION FULL MISSION TRAINER MINE WARFARE ENHANCEMENTS DUE 022399 POC Norman Hahn (407)380-4046 WEB: NAWCTSD Home Page, Request for Proposals, http://www.ntsc.navy.mil/contract/procure.htm. E-MAIL: HallCB@Navair.Navy.mil, HahnNR@Navair.Navy.mil. DESC: The Naval Air Warfare Center, Training Systems Division in Orlando, FL is seeking information from potential sources for mine warfare surf zone enhancements for Device 20G6 LCAC FMT. Background: The Landing Craft, Air Cushion (LCAC) vehicle is a high-speed, ship-to-shore, and over-the-beach amphibious landing craft that transports equipment, personnel, and weapons systems from ships located beyond the horizon, through the surf zone, and across the beach to landing points beyond the waterline. The LCAC Full Mission Trainer (LCAC-FMT), Device 20G6, is an LCAC command module simulator providing crew member training in the unique and complex handling characteristics of the Landing Craft, Air Cushion. The trainer provides full mission training, normal and casualty modes, for the LCAC crew -- operator, engineer, navigator, and group commander. The trainee station is integrated with a visual display system, both of which are mounted upon a six-degree of freedom motion system. The dynamic ocean environment includes sea states 0 through 4 as well as a sea state 3 surf model extending about 300 feet from the shore line into the sea. Two trainers were designed and built by Raytheon Systems Corporation. Requirements. System development. Device 20G6 shall be modified to incorporate the items described herein. Existing spare Input/Output and computational resources of Device 20G6 shall be utilized to satisfy the requirements stated herein. Enhancements. The ability to compute and display, in real time, a three dimensional surf zone for sea states 1 and 2 up to the beach and extending 1000' to the sea shall be added to a designated beach in an existing visual data base. The real-time visual and dynamic realism of the surf with waves breaking with natural frequency and size as they approach the beach as a function of water depth and sea state shall be simulated. Simulation requirements shall include the following: a. As a minimum, wave direction shall be parallel to the beach. Wave direction at selectable angles to the beach is preferred. b. Wave patterns shall generate real time dynamic forces and have the appearance of being random, c. Craft dynamics shall accurately respond in real time to waves underneath the craft in the surf zone, d. Craft dynamics shall respond to real time forces as a result of waves impacting the craft structure, e. Craft dynamics shall accurately respond in real time to the existing variable simulated wind, f. Craft dynamics shall respond in real time to the simulated launch of SABRE and DET, g. Craft dynamics shall respond to the simulated location and firing of a sequence of up to 14, 2000 pound, SABRE and DET boxes, h. Craft transitions from open ocean to surf zone to open ocean shall be smooth, i. Craft transitions from surf zone to land to surf zone shall be smooth. j. Visual simulation of the launch, flight, plume, and landing for SABRE and DET shall be incorporated, k. Aural simulation of the launch for SABRE and DET shall be incorporated, l. A Launch Control Box shall be simulated and located at the Group Commander Station, m. The Instructor Operator Station (IOS) shall be updated to provide the appropriate controls and displays for an Instructor at the IOS to play the role of a Launch Controller when one is not at the Launch Control Box and monitor the training situation. The cabin monitor pages of the IOS shall be updated to reflect the revised configuration of the Trainee Station due to the addition of the Launch Control Box. This request is for technical information describing the offeror's current capability to provide solutions to the requirements identified above. An estimate of the time required to deliver a solution shall also be included in the submitted data. Data shall be submitted to: NAWCTSD/Code 25721 Attn: Norman Hahn 12350 Research Parkway Orlando, FL 32826-3224. The purpose of this request is to determine the state of the technology in real time surf zone and hovercraft simulation and to evaluate the feasibility of initiating a program to seek detailed proposals for formal evaluation and development of some or all of the requirements of this request. Any future procurements developed as a result of the findings of this notice shall be synopsized in accordance with FAR 5.205. This is not a request for competitive proposals. no formal solicitation exists at this time. The US NAVY does not intend to award a contract on the basis of responses nor otherwise pay for the preparation of any information submitted. Acknowledgment of receipt of responses will not be made, nor will respondents be notified of evaluation of the information received. PLEASE NOTE A DECISION AS TO WHETHER THIS ACQUISITION WILL BE SET-ASIDE FOR SMALL BUSINESS HAS NOT YET BEEN MADE AND WE THEREFORE RESERVE THE RIGHT TO DETERMINE THE APPROPRIATE METHOD OF PROCUREMENT BASED UPON OUR ANALYSIS AND EVALUATION OF INFORMATION RECEIVED AS A RESULT OF THIS REQUEST. This is NOT a request for proposal, but for investigative purposes only and is not to be construed as a commitment by the Government. See Notes 25 and 26. Posted 02/01/99 (W-SN293372). (0032)
