COMMERCE BUSINESS DAILY ISSUE OF APRIL 5,2000 PSA#2572Naval Air Warfare Center Aircraft Division, Contracts Department,
Building 129-2, Highway 547, Lakehurst, NJ 08733-5083 17 -- CONSTANT RUNOUT VALVE (CROV)/RETRACT SYSTEM SOL
N68335-99-RFI-904 POC Jennifer Vaccaro, (732)323-5129, FAX
(732)323-4822 E-MAIL: Contract Specialist, vaccarojl@navair.navy.mil.
This is a Request for Information (RFI). There is no solicitation
available at this time. The Government will not pay for any information
received in response to this RFI, nor will the Government compensate
any respondent for any cost incurred in developing the information
provided to the Government. The Naval Air Warfare Center Aircraft
Division is seeking sources to design, develop, manufacture, test and
support a new Constant Runout Valve (CROV)/Retract System that utilizes
a microprocessor based feedback control system. The present CROV is
classified as an angle body globe valve, with a 5-inch orifice and is
part of the Mark 7 Arresting Gear. When the aircraft arresting hook
engages the cross-deck pendant, cable payout causes the crosshead/ram
motion to rapidly build cylinder pressure and force fluid through the
CROV into an accumulator. The purpose of the CROV is to throttle, or
regulate the flow of fluid and maintain cylinder pressure at a constant
level throughout most of the arrestment. Cylinder pressure may exceed
11,500 psi range, depending on incoming aircraft energy. Accumulator
pressure is maintained at 400-600 psi. During the course of the
arrestment, the valve closes at a rate which maintains a steady
cylinder pressure, until the aircraft velocity slows to the point where
cylinder pressure drops off and finally to zero when the arrestment is
complete. The present CROV is mechanically operated by a system of
cams, levers and cables. The improved CROV and Control System shall
consist of a control valve, method of hydraulic, pneumatic or
electrical actuation, all equipment necessary to supply power for the
actuation, sensors and computer control equipment to provide a desired
pressure profile in the Mark 7 accumulator, with uninterruptible power
supplies to keep the system operational for up to two hours and 120
complete arrestment and retraction cycles. The improved Mark 7 CROV and
control system is intended to increase the arresting capability aboard
CVN aircraft carriers for any combination of aircraft weight and speed
arrestment situations. The control system shall include preset
programming for any desired arrestment scenario. A more complete
description of the basic performance requirements/goals of the new
system will be provided to respondents. It is anticipated that the
program will be conducted as a phased acquisition, with up to two
awards for initial design to be downselected to a single production
contractor. Respondents will be asked to provide comments regarding
their technical capabilities, comments on the proposed requirements
description, and a discussion of their ability to provide Logistics
support for such a system. Included in the logistics discussion should
be comments on the company's capability/willingness to provide
drawings and software to the Government which will allow for
engineering investigations, and to allow for configuration control
evaluation, etc. Note that any drawings and software provided would not
be utilized for competition or disclosed outside the Government unless
unlimited rights are granted to the Government in the case of
commercial type components. Further, the Government requests comments
regarding the capability to acquire or be granted unlimited rights to
drawings and software in the event that the original equipment
manufacturer no longer makes the required component. It is anticipated
that this procurement will involve Militarily Critical Technology and
will be subject to the ITAR. See Note 8. It is mandatory that
respondees provide a valid executed DD Form 2345. The RFI package is
anticipated to be available no later than 24 April 2000, with responses
to the package anticipated to be due in 30 Days. Requests for the RFI
package shall be submitted to Ms. Jennifer Vaccaro, Naval Air Warfare
Center Aircraft division, Code 252220B129-2, Highway 547, Lakehurst, NJ
08733-5082, who may be reached at (732) 323-5129, FAX (732) 323-4822 or
