- Description
- Background This is a Request for Information (RFI) only. This is not a solicitation announcement for proposals, there is no solicitation package available and no contract will be awarded as a result of this announcement. The Naval Air Warfare Center Aircraft Division (NAWCAD) Lakehurst is seeking information from industry that will assist in the assessment of new technology for the purpose of detecting intermittent faults in avionics. This information will assist the NAWCAD in determining an acquisition strategy for a Joint Intermittence Tester (JIT). The Department of Defense aviation communities require a Joint Intermittence Tester (JIT) to detect intermittent faults in Weapons Replaceable Assemblies (WRA)/Line Replaceable Assemblies (LRU). These faults are sometimes referred to as: No Fault Found (NFF), Can Not Duplicate (CND), No Evidence of Failure (NEOF) and Nothing to Report (NTF). Intermittent avionic chassis faults have been identified as a major cost and operational degrader for all US armed forces aviation platforms. The following definitions relate specifically to this RFI. Definitions Fault Detection: The ability to identify that an intermittent fault is present in the WRA/LRU Fault Isolation: The ability to spatially locate a fault in the WRA/LRU to the circuit exhibiting an intermittent fault. Persistent Faults: Non-intermittent faults. The anomalies caused by these types of faults do not abruptly appear, disappear, or undergo large changes over time or with changes in state of the aircraft or aircraft wiring system, such as when the aircraft is in flight, is performing ground operations, or is on the ground and not operating. The primary cause of persistent faults is mechanical damage to the insulation on a wire or wires (chafe damage, cuts into the insulation, etc.) that results in the exposure of the metallic conductor to the environment. If the exposed conductor is in continuous (persistent) anomalous contact with another conductor (on a different chafed wire, cable, or wire-harness assembly shield; aircraft components; or aircraft structure), then a persistent short may result. Persistent faults can also be caused by breaks in electrical continuity of the conductors (i.e., opens) due to broken or severed wires. Fault detection for persistent faults is typically accomplished with various electrical meters (an ohmmeter, a digital multi-meter), and fault location is typically accomplished via troubleshooting techniques or by utilizing a time-domain reflectometer or similar tester. Intermittent Faults: Non-persistent faults. The anomalies caused by these types of faults abruptly appear, disappear, or undergo large changes over time or with changes in the state of the aircraft or aircraft system, such as when the aircraft is in flight, is performing ground operations, or is on the ground and not operating. The primary physical cause of intermittent faults in a WRA/LRU is mechanical damage to the insulation on a wire or wires or to lower-level assemblies, including circuit card assemblies (CCA), and loose or broken solder joints that result in the exposure of the metallic conductor to the environment. If the exposed conductor is in close proximity to but not in continuous (persistent) contact with another conductor (on a different chafed wire, cable or wire harness assembly shield, WRA/LRU components or aircraft structure), then an intermittent short condition may arise when the damaged item is subjected to environmental stimuli (e.g., aircraft flight dynamics, airframe vibration, temperature cycling). Similarly, an intermittent open condition may result when a damaged conductor maintains electrical continuity only during static conditions but sporadically loses continuity when the aircraft is subject to certain flight conditions or other stimuli. Intermittent faults manifest when the aircraft is subjected to the previously mentioned environmental stimuli, and they can disappear when the aircraft is not operating on the ground; hence, they are unpredictable and difficult to detect. Fault isolation for intermittent faults at the intermediate level (I-level) of maintenance is typically accomplished via troubleshooting techniques. Depot-level testers require an environmental chamber and vibration table and are not suitable for the I-level. No electrical tester that is able to completely and reliably fault isolate intermittent faults in a WRA/LRU at the I-level is known to be in service and supporting any Department of Defense (DoD) aircraft weapon systems. Joint Intermittent Tester (JIT): An aircraft system tester that can reliably and accurately fault isolate and fault detect intermittent faults in a WRA/LRU. The DoD is seeking to procure / develop such a tester in the near future. Request for Information: The NAWCADLKE is seeking information from industry regarding avionic intermittent fault detection technology. Please provide the following information in your response: 1) General description of your avionic intermittent fault detection product / technology. 2) Identification of critical enabling technologies of your avionic intermittent fault detection JIT. Include technology readiness level (TRL) of your JIT product / technology and a summary of field usage, test and demonstration results. Describe, if applicable, any additional stimuli that must be applied to the unit under test (e.g. physical manipulation to induce faults, etc.). 3) Overview of your JIT concept of operation (including user operating manual if available). Discuss the operator - JIT interface, JIT - WRA/LRU interface and any related issues. Discuss anticipated and demonstrated benefit versus cost of utilization of your JIT and any demonstrated Return on Investment (ROI). 4) Discuss critical information required for the use of your JIT (e.g. lengths and types of wires, chassis schematics; etc.) 5) Discuss fault detection reliability, including types of detectable faults and minimum fault durations, and fault isolation accuracy. 6) Describe environmental testing test methods and results that your JIT has been subjected to. Discuss environmental conditions in which the JIT is approved to operate (e.g., electromagnetic susceptibility or emissions, operating / storage temperature, humidity, altitude, and shock.) Please provide a detailed description of any explosive atmosphere testing. 7) If applicable, provide customer testimonials with references. Provide your point(s) of contact. 8) Provide information about your company /organization including a brief description of your company /organization; Small / large business, 8A, hub-zone, veteran-owned status; and any past or present Small Business Innovative Research (SBIR) awards related to your JIT. 9) Provide any additional information you desire. General Guidelines How to Respond: Responses to this RFI should be submitted via email to Keith Welge at keith.welge@navy.mil, no later than 60 days from the date of this posting. The Government may elect not to discuss submissions received in response to this RFI with individual responders. There is no requirement to respond to the RFI in order to be eligible to propose on the planned RFP. However, the Government places tremendous value on the information received and may utilize it to finalize its acquisition strategy. DISCLAIMER The Government does not intend to award a contract on the basis of this RFI. This RFI is issued solely for information and planning purposes and does not constitute a solicitation. In accordance with FAR 15.201(e) responses to this notice are not offers and cannot be accepted by the Government to form a binding contract/agreement. The Government will not pay for any information received in response to this request, nor will the Government compensate any respondent for any costs incurred in developing the information provided to the Government. Responses to this RFI will not be returned. Respondents will not be notified of the results of the review. NO FORMAL SOLICITATION EXISTS AT THIS TIME.
