This is an Air Force SBIR/STTR contract topic for US for-profit small businesses with 500 or fewer employees to build a reduced-order engineering model predicting hydrodynamic spurt formation in shaped-charge jets. It is for defense-adjacent R&D firms with physics, simulation, or warhead-modeling capability; companies without that technical background, and any nonprofit, should not bother applying.

SBIR/STTR Phase I-II contract topic for US small businesses (≤500 employees, majority US-owned) to develop a computationally efficient reduced-order engineering model predicting hydrodynamic spurt formation in shaped-charge jets, enabling faster warhead design iteration for the Air Force.
This topic seeks the development of a computationally efficient engineering-level model to predict the formation and characteristics of the "spurt" in fluid cavity created jets. The hydrodynamic spurt is the initial, often unsteady, ejection of material from the liner, preceding the formation of the main, stable jet. Current hydrocodes can model this phenomenon but are computationally expensive and ill-suited for rapid design iteration. This project will develop a validated, reduced-order model that accurately predicts spurt velocity, mass, and geometry as a function of liner material, geometry, and threat characteristics, enabling faster design and optimization of advanced warheads.

SBIR.gov copies agency solicitations and can lag behind them; the official solicitation is the final word.
Small businesses only: a for-profit US business with 500 or fewer employees, including affiliates.
More than 50% owned and controlled by US citizens or permanent residents (some agencies also accept majority ownership by venture capital, hedge fund or private equity firms; the solicitation says).
SBIR: the principal investigator is primarily employed by the business. STTR: the business partners with a US nonprofit research institution or university, which does at least 30% of the work.
