STATEMENT OF WORK (SOW)/PERFORMANCE WORK STATEMENT (PWS)

( Impact Modeling)

1.0 Background

Naval Undersea Warfare Center Division, Newport (NUWCDIVNPT), is being funded by the to execute a 6.1 basic research project investigating the physics of high-speed water entry. One sub-task of this effort involves modeling the water impact forces and associated structural response. This Statement of Work (SOW) describes the need for analytical modeling that enables analysis without the need for computational fluid dynamics (CFD) and finite element analysis (FEA) simulations.

1.1 Places of Performance

The work shall be performed at the Contractor’s facilities

1.2 Authorized Users

1.3 Sponsors

1.4 Types of Funding

2.0 Scope

The Contractor shall perform analytical modeling to describe the structural response of a simplified two-body compliant body during water impact. The analysis should accommodate arbitrary nose shapes. The Contractor shall validate this model against experiments performed by the contractor in their laboratory. The Contractor shall also perform analytical modeling to describe the structural response of a continuous elastic body during water impact. By analytical modeling, we mean a modeling approach that yields a set of equations that can be evaluated in Matlab over a range of parameters, without requiring the use of CFD and/or FEA.

3.0 Applicable Documents

None.

4.0 Technical Requirements

4.1 Generation of model documentation

The contractor shall:

4.1.1 Derive and document an analytical model to describe the structural response of a simplified two-mass compliant body during water impact. The analysis should accommodate arbitrary nose shapes. The contractor shall express the resulting model in a set of mathematical equations that can be implemented in MATLAB software. A computational fluid dynamics (CFD) finite element/finite volume model is not an acceptable form of the model.

Deliverable: CDRL A001 – Technical Report.

4.1.2 Perform experiments to validate the model derived in 4.1.1. The experiments must consist of a two-mass compliant body that contains an on-board accelerometer to measure impact accelerations during impact with water at speeds ranging from 1-4 m/s. The water impact must occur with the body velocity vector nominally perpendicular to a flat water surface. The impacts must also be captured with high speed cameras. At least 3 distinct water impact velocities are required, with at least 4 repeats at each velocity (12 tests).

Deliverable: CDRL A002 – Test Report

4.1.3 Derive and document an analytical model to describe the structural response of a continuous elastic body during water impact. The contractor shall express the resulting model in a set of mathematical equations that can be implemented in MATLAB software.

A computational fluid dynamics (CFD) finite element/finite volume model is not an acceptable form of the model.
