**R-2A activity** of project 613002 — Aerospace, Chemical and Material Sciences  
**Program element:** 0601102F — Defense Research Sciences  
**Component:** U.S. Air Force · **Budget Activity:** 1  
**Vintage:** President's Budget PB2027

## Summary

This activity requests $28.3M in FY2027, 34% of project 613002, down 8.1% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** - Continue investigating the characterization, modeling, and exploitation of interactions between the unsteady aerodynamic flow field and the dynamic air vehicle structure to enable enhanced performance in next-generation Department of the Air Force systems. - Continue to explore the synergy gained from an interdisciplinary integration of fluid mechanics, high-performance structures, and thermodynamics research.

**FY2026 to FY2027 change.** FY 2027 decreased compared to FY 2026 by $2.490 million due to decreased emphasis on Aero-Structure Interactions and Control. This reduction reflects programmatic adjustments to the DAF Science and Technology portfolio for strategic realignment to optimize core research areas and improve resource efficiency. This will result in approximately 10 fewer grants awarded in Aero-Structure Interactions and Control.

## Before the request year

**FY2026 plans — current year.** - Investigate the characterization, modeling, and exploitation of interactions between the unsteady aerodynamic flow field and the dynamic air vehicle structure to enable enhanced performance in next-generation Department of the Air Force systems. - Explore the synergy gained from an interdisciplinary integration of fluid mechanics, high-performance structures, and thermodynamics research.
