NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 31 May 2029.

Abstract

Turbulent motion of fluids appears in many important settings, including weather systems, ocean currents, aircraft flows, wind energy, and industrial mixing. Turbulence looks extremely complicated with swirls of many different sizes. This project addresses a fundamental puzzle: why does violent, intense turbulence often result in little net energy transfer between swirls of different sizes? The reason is that energy…
