Ogive (ogee) delta wing — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/ogive-delta-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 - An ogee wing curves its leading edge from very high sweep at the root to lower sweep outboard. NASA's ogee test aircraft went from 52.5 deg to 77 deg root sweep and 55.8 deg minimum, cutting AR from 2.02 to 1.70 while adding area (NASA Ames). - Its steady leading-edge vortices showed no detachment to 25 deg AoA and lowered approach speed by 10-15 kt, but pitch stability was neutral to slightly unstable on approach (NASA Ames). Concorde's slender ogival delta had no flaps or slats, only six elevons, and relies on vortex lift to fly slowly (Heritage Concorde). - ONERA estimated about 30% lift increase near the ground for this planform (NASA Ames, ONERA comments). - Used on: Concorde, Douglas F5D-1 (NASA ogee test). - 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 Ogee LE sweep root / minimum 77 deg / 55.8 deg NASA Ames AR basic -> ogee 2.02 -> 1.70 NASA Ames Wing area basic -> ogee 557 -> 661 ft^2 (span 33.5 ft) NASA Ames Vortex steady to 25 deg AoA, 8 deg sideslip NASA Ames Ground-effect lift increase (ONERA estimate) about 30% NASA Ames (ONERA) Concorde control surfaces 6 elevons, no flaps or slats Heritage Concorde Reference build span 335, root 600, LE sweep 77 deg root computed (1:30 of 33.5 ft span) Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - NASA Ames (Drinkwater & Rolls), AGARD Report 538: Flight Experience with the Ogee Wing at Low Speed (1966) — web — Publisher's page; dimensions are facts — https://ntrs.nasa.gov/api/citations/19670020235/downloads/19670020235.pdf - Heritage Concorde: The Wing — web — Publisher's page; dimensions are facts — https://www.heritageconcorde.com/the-wing Free files (Xem Studio Design License, Xem Studio; STEP + STL, 1 parts): https://xemstudio.com/files/hardware/ogive-delta-wing/index.json API: https://xemstudio.com/api/geometry?object=ogive-delta-wing
