Airbus

i built a turbofan https://app.confbuild.com/p/z459 now I want to build a complete Airbus as detailed as possible with give budget

A rigorous top-level engineering document: mission profile and payload-range targets, regulatory framework summary (CS-25/FAR-25 scope), weight and sizing estimation with worked calculations, configuration trade studies (wing planform, engine count/placement reusing the user's turbofan project, fuselage cross-section), and a frozen baseline specification sheet that all later milestones build against.

Complete airframe geometry expressed as runnable parametric CAD code (CadQuery/OpenSCAD + Python): fuselage loft with frames and stringers layout, wing with spars, ribs, control surfaces and high-lift devices, empennage, landing gear geometry and retraction kinematics, plus structural load-path notes and a build script that exports STEP/STL per assembly. Delivered as a documented code repository.

Integration of the user's turbofan into the airframe: nacelle and pylon design, inlet/exhaust sizing, fuel system architecture. Plus full systems engineering for hydraulics, electrical generation/distribution, environmental control, flight controls (fly-by-wire architecture), and avionics — delivered as schematics-as-code (Python/Graphviz/SysML-style text models), interface control documents, and failure-mode tables per system.

A working Python simulation package: aerodynamic model (lifting-line/panel-method implementation), stability and control analysis, 6-DOF flight dynamics model, takeoff/climb/cruise/landing performance calculators, and an automated test report comparing results against the baseline spec from Milestone 1. Includes a runnable demo flight scenario as proof the digital aircraft 'flies'.

A production engineering package: full hierarchical bill of materials with material specs and realistic cost estimates, manufacturing process selection per major part (composite layup vs. machined vs. sheet metal), assembly sequence plan with jig/tooling concepts, and an honest budget reconciliation document mapping what the user's stated budget can actually achieve (e.g., subscale demonstrator vs. full article) with staged spending options.

Certification-style closing package: functional hazard assessment, system safety analysis for critical systems, structural reserve-factor summary, a phased flight test plan (ground tests, taxi, first flight, envelope expansion) with test cards, plus a polished project showcase document tying all milestones together for backers.
