OBJECTIVE: Design an Inlet Debris Monitoring System (IDMS) to detect when jet engines ingest Foreign Object Damage (FOD) [Ref 1] and quantify its sensitivity to typical Navy/Marine Corps flight and environmental operating conditions.
DESCRIPTION: Foreign Object Damage (FOD) is a top engine removal driver for nearly every platform in naval aviation. Debris ingestion causes unacceptable readiness and safety levels for a variety of fixed- and rotary-wing platforms. FOD is responsible for seven Class A mishaps (i.e., an accident that leads to fatality, dismemberment, or greater than $2 million in damages) (Ref 4) and cost the Naval Aviation Enterprise (NAE) over $400 million in the past three years. The FOD Program, which applies research to understand, quantify, and prescribe solutions to FOD that require coordination across commands and installations, projects FOD will cost the NAE > $2 billion over the next five years.
The FOD Program is developing a method for synthesizing and analyzing data from novel sensing technologies to quantify the risk of operating aircraft in an environment with a dynamic debris field. The prototype, known as the FOD System-of-Systems Approach (SOSA), enables the integration of multiple sensor suites, data logistics, data fusion, data analysis, and automation. The purpose of the FOD system is to calculate and remediate the risk of engine FOD strikes.
The FOD Program requires an on-wing, Inlet Debris Monitoring System (IDMS) capable of detecting when an engine ingests debris and particulate. The IDMS will act as feedback to the FOD SOSA to continually refine the FOD SOSA’s predictive analytical capability and improve the FOD SOSA’s ability to reduce FOD events.
Topic requirements include, but are not limited to:
Flight and environmental conditions an IDMS may experience, and thus affect a Pd and Pfa, include (*Note the following conditions are not a comprehensive list of factors):
Common examples of discrete events, consisting of both hard and soft debris, include (*Note the following materials are not a comprehensive list of FOD):
A Minimum Viable Product (MVP) of an IDMS should be flight qualified and integrated into at least one test aircraft and possess the ability to:
The IDMS should:
PHASE I: Demonstrate the feasibility of the technology through a series of Technology Readiness Level (TRL) maturation events. Demonstrate the technology’s basic scientific principles. Demonstrate the feasibility of applying the technology to an IDMS by designing, testing, and validating a basic breadboard laboratory experiment. The Phase I effort will include prototype plans to be developed under Phase II.
PHASE II: Develop, demonstrate, and validate the breadboard and test it in an environment that represents the speed and particulate size/material typical of a Navy/Marine Corps environment; begin studying Pd and Pfa.
Produce a prototype system that consolidates the breadboard into an operationally representative IDMS configuration; increase the testing rigor to include representative mechanical effects such as engine acoustics and vibrations and aerodynamic effects such as temperature, pressure, and non-uniform airflow. Characterize the prototype’s performance when exposed to these mechanical and aerodynamic effects.
Refine the prototype to be worthy of flight qualification. Quantify the Pd and Pfa under varying operational and environmental conditions (see Description section for details) before exiting this stage and the IDMS does not pose a safety of flight risk to an aircraft.
PHASE III DUAL USE APPLICATIONS: Finalize the prototype for a selected Navy and/or Marine Corps aircraft. Integrate the prototype into the select aircraft and the SOSA. Support flight-testing. Work to enable the retrofit of operational aircraft with the IDMS.
FOD costs the commercial aviation industry over $2 billion per year [Ref 4] and an average of $43 million per year at major U.S. hubs. The FOD Program projects that the FOD SOSA’s risk remediation techniques, enabled by the IDMS subject to this topic, will increase commercial aircraft availability by between 15 and 30 aircraft per airfield per year and reduce cost of ownership for airlines by between $20 million and $50 million per airfield per year where the SOSA is operational.

** TOPIC NOTICE **
The Navy Topic above is an "unofficial" copy from the overall DoD 21.2 SBIR BAA. Please see the official DoD Topic website at rt.cto.mil/rtl-small-business-resources/sbir-sttr/ for any updates.
The DoD issued its 21.2 SBIR BAA pre-release on April 21, which opens to receive proposals on May 19, 2021, and closes June 17, 2021 (12:00pm edt).
Direct Contact with Topic Authors: During the pre-release period (April 21 thru May 18, 2021) proposing firms have an opportunity to directly contact the Technical Point of Contact (TPOC) to ask technical questions about the specific BAA topic. Once DoD begins accepting proposals on May 19, 2021 no further direct contact between proposers and topic authors is allowed unless the Topic Author is responding to a question submitted during the Pre-release period.
SITIS Q&A System: After the pre-release period, proposers may submit written questions through SITIS (SBIR/STTR Interactive Topic Information System) at www.dodsbirsttr.mil/topics-app/, login and follow instructions. In SITIS, the questioner and respondent remain anonymous but all questions and answers are posted for general viewing.
Note: Questions should be limited to specific information related to improving the understanding of a particular topic’s requirements. Proposing firms may not ask for advice or guidance on solution approach and you may not submit additional material to the topic author. If information provided during an exchange with the topic author is deemed necessary for proposal preparation, that information will be made available to all parties through SITIS. After the pre-release period, questions must be asked through the SITIS on-line system.
