EGG PLANE TRIANGLE NOSE (EGG PLANE)

To design this "egg-plane" for high-capacity passenger transport, we must scale the semi-ellipsoidal lifting body to accommodate wide-body seating while maintaining the structural integrity of an ultra-lightweight airframe.
1. Scaling for 350 vs. 700 Passengers
Scaling a lifting body for high capacity requires balancing internal volume with aerodynamic lift. A 350-passenger variant is comparable to a long-range wide-body like the Airbus A350, while a 700-passenger version approaches the scale of a Flying-V concept or a double-deck wide-body.
350 Passengers: Requires a pressurized semi-ellipsoidal cabin approximately 65–70 meters in length. The "6-wide" wing root serves as the primary structural attachment point for the payload.
700 Passengers: Utilizes a "multi-bubble" or intersecting circular tube internal structure to manage pressurization loads across a much wider semi-ellipsoidal span. This creates a large, uninterrupted internal space for double-deck or wide-set seating.
2. MVW Bracing for Ultra-Lightweight Support
To achieve an "ultra-light" rating at these scales, the design moves away from traditional cantilever wings toward Truss-Braced Wing (TBW) technology, using MVW (Multi-Variable Weight-optimized) bracing paths.
Structural Efficiency: Diagonal struts create a large structural triangle between the lower fuselage and the wing, stabilizing the inner section and allowing for thinner, higher-aspect-ratio wings that can be up to 39% lighter.
Load Path Optimization: Bracing members are primarily loaded in tension/compression, reducing the bending moments at the wing root and allowing the carbon-fiber skin to be thinner and more aerodynamic.
3. Ultra-Light V-Shaped Windows
Standard circular windows are replaced with V-shaped (Angular) Windows optimized via Tailored Fibre Placement (TFP) to reduce weight while maintaining safety.
Load Path Redirection: Modern TFP allows fibers to be guided precisely around the V-shaped openings. This reinforces the "corners" of the V-shape, which traditionally act as stress concentrators, making them as strong as rounded windows but with significantly reduced frame weight.
Visibility & Branding: Similar to Boeing's signature V-shaped cockpit windows, these windows provide wide-angle visibility while integrating directly into the aerodynamic lifting surface of the egg-plane’s upper fuselage.
