AEROPROPSIM / RESEARCH COMPARISON

PROWIM validation

Beaver propeller and rectangular wing. Angles of attack: 0° and 4°.

MODEL & PUBLISHED EXPERIMENT0° / 4°
Zero- and four-degree PROWIM loading comparisons. Solid curves show model predictions, open symbols show experiment, and the lower row shows propeller-on changes and dashed radial BEMT sensitivity.
At zero degrees: model and experimental wing-normal loading, with propeller-on change and radial BEMT sensitivity below.
At four degrees: model and experimental wing-normal loading, with propeller-on change and radial BEMT sensitivity below.

Top: wing-normal coefficient cₙ. Solid curves show the phase-mean prescribed-wake model; open markers show published experiment. Grey: wing alone. Blue: inboard-up. Orange: outboard-up.

Bottom: propeller-on change Δcₙ. Dashed curves show radial BEMT sensitivity. Shading indicates the projected propeller disk; the dotted line marks its centre.

Steady axial, one-way coupling. Wing-normal coefficients use freestream dynamic pressure. This research comparison reproduces the selected panels from the supplied figure; models and validation continue to evolve.
