Summary

The Department of Defense (DOD) is seeking proposals for a Small Business Innovation Research (SBIR) Phase I project titled "Test Noise Reduction / Energy Capture Study". The research topic focuses on the development of potential solutions for noise reduction and energy recapture in future engine test cell designs. The goal is to comply with the Air Force's objective of achieving 100% carbon-free electricity by 2030. The project will involve evaluating jet engine test energy recapturing and noise reduction through computer modeling and a developed subscale physical model. The project duration is 24 months, and the deliverables include a documented Analysis of Alternatives, noise measurements in decibels (db), and final electrical recapture in watts. The Phase II project will demonstrate a feasibility plan, implementation plan, and a functional physical sub-scale model. The Phase III project aims to integrate design elements into the Agile Common Engine Test Cell (ACETC) construction projection. The technology and research have potential applications in the commercial industry, especially for new construction opportunities.

OBJECTIVE: Development of potential solutions for noise reduction and energy recapture to be used in future engine test cell designs. Documented Analysis of Alternatives and sub-scale system should be produced to demonstrate the optimized solution.

 

DESCRIPTION: Initial study to determine the feasibility and identification of potential solutions for the incorporation of energy capture and advanced noise reduction in future ACETC facility plans in an effort to comply with the Air Force's goal of 100% carbon-free electricity by 2030. The testing of jet engines produces an immense amount of heat, vibration, and air. There is potential opportunity to capture the forced air and heat to recycle energy. To protect those working in the facility and provide a safe working environment, advanced noise reduction solutions should be considered to avoid the need of excessive PPE.

 

PHASE I: This will be a SBIR phase I project with a 24 month Period of Performance. This project will evaluate jet engine test energy recapturing and noise reduction.  The scope of the project validation through computer modeling and verification through a developed subscale physical model utilizing a minimal of 20 pound thrust jet engine to analyze energy recapture and noise reduction. PMXG is open to evaluations of all energy recapturing opportunities as well as all noise reduction opportunities, through a documented Analysis of Alternatives.   Noise measurements are expected to be is Decibel (db). Final electrical recapture is expected to be in Watts.  Sub-scale computer model will be generated/developed by applicant, demonstrating the test envelope, engine, air flow, electric consumption, electric production, a noise levels. It is important to keep air flow in the test envelope laminar, so the performance of the engine is not compromised. An optimized demonstration of physical sub-scale model with measured electrical and noise parameters is expected as part of the deliverable.  An initial study, multiple presentations, a working prototype (with 20 lb-thrust or higher engine test) and air flow monitoring and noise level readings are some milestones in this project.

 

PHASE II: This will be a SBIR phase II project with a 24 month Period of Performance. This project will demonstrate a feasibility plan, implementation plan, and a demonstration of a functional physical sub-scale model (with 20 lb-thrust or higher engine test) with physical measurements. Documented Analysis of Alternatives shall be evaluated to show a robust poka-yoke design to optimize airflow constraints and reduce backflow opportunities, utilizing the physical sub-scale model for confirmation. Airflow, noise reduction and energy production shall be evaluated for variations in Type, Model, Series (TMS) engines.  It is important to keep air flow in test envelope laminar, so the performance of the engine is not compromised. Scalability plans for test cell, engine, models and supporting documents shall be provided to Air Force jet engines to project requirements. Simulation models will be delivered with editable features to the test cell and TMS for internal Government use. Implementation plans to store captured energy into a local sub-station will be a deliverable. The optimized demonstration of physical sub-scale model with measured electrical and noise parameters is expected as part of the deliverable. Applicate will provide the Government formal studies, multiple presentations, a working optimized prototype (with 20 lb-thrust or higher engine test) with air flow monitoring, energy recapturing and noise level readings, scalability plans are some milestones in this project.

 

PHASE III DUAL USE APPLICATIONS: This will be a SBIR phase III project is to integrate design elements, where feasible, into the Agile Common Engine Test Cell (ACETC) construction projection.  This “Test Cell of the Future” concept opens up the perfect aperture to explore innovative green technology ideas and actively seek to reduce known safety challenges.  If economically feasible, these concepts could apply to the commercial industry, especially for new construction opportunities.  With construction conceptionally planned to begin in CY29, the opportunity to change tomorrow starts with today.
