A -- FY99 ARL BAA AMENDED SYNOPSIS SOL DAAD17-99-R-ARL-BAA SOL DAAD17-99-R-ARL-BAA POC M. Corbett ARL Acquisition Integration Officer (301) 394-3690 mcorbett@arl.mil FY99 ARL Broad Agency Announcement -- Amendment 5 -- This amendment is to announce that the U.S. Army Research Laboratory, Sensors and Electron Devices Directorate, is soliciting concept papers (White Papers) for "an energy absorption system for use in munitions battery testing." This amendment is available in its entirety on the ARL BAA homepage (http:w3.arl.mil/contracts/99arlbaa.htm). "Offeror(s) shall conduct feasibility or concept studies intended to ascertain the potential design and performance of a system to augment or replace an existing device. The energy absorption system will be used to receive impacts from 300-350 gram, cylindrically-shaped, projectiles moving at 190-220 feet per second, which it must decelerate, in a controlled manner, to a complete stop; with impact occurring inside a 12-inch long, 2-inch ID tube, open at both ends, while rotating at speeds up to 300 revolutions per second. The projectile must be brought to a stop in the tube, as it spins. (The projectile currentlyhas two dowel pins extending from its forward face that impale themselves in a column of plywood blocks, that are positioned against a moveable mass. The plywood expands radially upon impact and the resulting friction between the plywood and the bore of the spinning tube yields a high rate of angular acceleration for the projectile.) The duration of the deceleration pulse generated by the plywood blocks is inadequate. This solicitation seeks an energy absorption system that generates a level of deceleration of at least 2400 'gees" ('g') for a minimum of five (5) milliseconds. Offerors must include information regarding any determination, in the analysis and/or preliminary design, that indicates the need for a greater initial velocity and/or longer stopping distance. The concept offered must include an absorption system that causes or permits the projectile to rapidly assume the rotational velocity of the spinning tube. The concept must clearly show that any part of the absorption system that will contact thebore of the spinning tube before, during and after the impact of the projectile must be electrically non-conductive. The absorption system should generate a minimal amount of particulate matter and/or debris during usage. It is expected that the absorption system will be utilized 200 times per year on average, with a maximum use rate of 600 times per year. Offerors whose abstract is determined to be consistent with the intent of this solicitation may be invited to submit full technical and cost proposals. The period of performance of this project shall be 7 April 2000 to 6 April 2001. EVALUATION CRITERIA: Concept papers received shall be evaluated in accordance with the evaluation criteria listed in the FY99-00 ARL Broad Agency Announcement (BAA). Selection of concept(s) for award will be made to the offeror(s) whose concept is considered most advantageous to the Government, price and other factors considered; (i.e. an independent Government assessment of the probability of success of the offered approach and the availability of funding). The Government reserves the right to select for award any, all, part or none of the responses received. Funds are not presently available for this BAA project; and no contract award will be made until appropriated funds are made available from which payment for contract purposes can be made. Questions concerning contractual, cost or pricing or proposal matters may be directed to M. Corbett at (301) 394-3690. Individuals or firms/institutions with questions of a technical nature may contact the Government technical representative, J. Swank at (301) 394-3116. CLOSING: Concepts are due by 2:00p.m. eastern time on 8 May 2000. One original and two copies of the concept are to be submitted directly to: U.S. Army Research Laboratory, ATTN: AMSSB-ACA-P/BAA/M.Corbett/T2, 2800 Powder Mill Road, Adelphi, MD 20783-1197. All responsible sources may submit an offer which will be considered by the Agency. No telephone requests shall be honored. Posted 04/05/00 (W-SN441441). (0096)
