The Department of Defense (DOD) is seeking proposals for the topic of "Real-Time In-Flight Aircraft State Estimation" as part of their Small Business Technology Transfer (STTR) Phase I program. The Navy branch is specifically interested in developing a method that utilizes existing aircraft sensors to estimate important flight parameters such as weight, center of gravity, airspeed, wind speed, and other critical aircraft states. The goal is to reduce the need for redundant sensors, improve mission success rates, and enhance pilot situational awareness. The proposer should validate the estimation methodology using simulation or flight test data and determine the accuracy of the estimations. The project will consist of a Phase I feasibility study, followed by Phase II validation using simulation or flight test data. In Phase III, the estimation methodology will be incorporated into a flight control algorithm to identify failed sensors and provide accurate aircraft state information. The successful implementation of this technology would benefit both commercial and military platforms by reducing system complexity, cost, and weight. The solicitation is currently open, with a closing date of June 12, 2024. For more information and to submit a proposal, visit the DOD STTR website.
