About this opportunity
The Defense Advanced Research Projects Agency (DARPA) has issued a Special Notice seeking information on ideas, methodologies, and approaches for a Wing Over Wave Test related to the Liberty Lifter program. The Liberty Lifter program aims to design, build, float, and fly an affordable, innovative seaplane to operate efficiently in ground effect.
The purpose of this test is to generate representative force (lift, drag) and moment measurements for a 12-foot span, 3-foot chord, aspect ratio 4 rectangular wing with a NACA 4415 airfoil section, without any high-lift devices, propulsion, or moving/adjustable control surfaces. The test will utilize a 64-port pressure tap array, a five-port pressure probe, and a six-degree-of-freedom force gauge to measure the aerodynamic forces and moments. Responses to this Request for Information are due by 4:00 PM Eastern Time on July 7, 2024. No set-aside or eligibility criteria are specified, and no intellectual property or proprietary information will be shared outside the U.S. Government.
Notice text
DARPA seeks to evaluate a large scale aerodynamic model of a canonical wing planform in ground effect over waves. A generic wing planform, section, and aspect ratio were chosen to generate representative force (lift, drag) and moment measurements to enable comparison to Computational Fluid Dynamics (CFD) results and tuning of CFD models for Liberty Lifter and future wing-in-ground effect vehicle designs. The test article is a rectangular wing planform with 12-foot span, 3-foot chord, aspect ratio 4, with a constant NACA 4415 airfoil section and no high-lift devices, propulsion, or moving/adjustable control surfaces. Two vertically-oriented support struts in the upper wing are incorporated into the model to enable mounting and orientation in the test facility. The test article incorporates a 64-port pressure tap array, a five-port pressure probe to be mounted ahead of the model in the freestream, and a six-degree-of-freedom Kistler force gauge to be attached to the mount assembly to enable aerodynamic force and moment measurements.
