Parasol wing — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/parasol-wing/ (sheet CC BY 4.0; files Xem Studio Design License, https://xemstudio.com/license/) Basis: Design rules and figures from the cited sources; example geometry by Xem Studio Catalog version: 2026-10-20 Sizes: see table below - A parasol wing sits above the fuselage on struts or a pylon. NASM contrasts the Catalina's parasol wing, which needed external bracing, with the Mariner's gull wing that did not (Smithsonian NASM). - Like a high wing it adds stable dihedral effect, so it needs little geometric dihedral (Kitplanes, Wainfan, on high wings). - On flying boats the raised wing keeps engines and props above spray (NASM, PBM entry). - Used on: Consolidated PBY Catalina. - The file is a reference example built by Xem Studio from the numbers above. Sizes the sources do not fix are illustrative; scale the example to your own vehicle. parameter value or range source Bracing parasol wing needed external bracing (Catalina) Smithsonian NASM RC with ailerons, high/parasol about 0-2 deg dihedral McCombs 1994 (high wing) Reference build 1000 x 200 mm, 2 deg McCombs Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Smithsonian National Air and Space Museum: Martin PBM-5A Mariner — web — Publisher's page; dimensions are facts — https://si.edu/object/martin-pbm-5a-mariner:nasm_A19730270000 - Kitplanes (B.
