Adnan Khan

BS Mechanical Engineering — Binghamton University · Queens, NY

I build simulation tools. My main project is Astraea, an open-source rocket engineering workstation — 3D airframe design, Rust/WASM 6-DOF flight simulation, Monte Carlo dispersion, and comparison against real flight logs. I also build RecoverySys, a local-first recovery-bay planner, and Plainhand, a job-application assistant that runs on your own computer.


Background

Rocketry (Aerobing Team, Binghamton) — Led a 4-person dual-deploy recovery system build from design through fabrication (carbon fiber, black powder assembly, precision machining). Separately, ran FEA stress analysis on a composite pressure tester: 308K+ nodes, cross-validated against hand calculations, applied ASME pressure vessel and ASTM D3039 standards. Factor of safety of 3.14 at 2,000 psi working pressure.

NYC DEP (Mechanical Engineering Intern, 2024–2025) — Designed sewer infrastructure plans in AutoCAD, investigated chronic failures using GIS and CCTV inspection data, and built a digital inspection database that automated maintenance scheduling. Also inspected backflow prevention assemblies across all five boroughs.

Formula SAE — Designed suspension components (rotors, tabs) in coordination across drivetrain and steering teams.


What I'm building toward

My simulation work sits at the edge of where physics-based models meet machine learning — surrogate models, physics-informed neural networks, fast approximate simulation. recoverysys-surrogate is now shipped: a neural network trained on 2,000 physics-engine simulations that predicts flight outputs in about 2 µs per sample, roughly 22,000× faster than the solver. That's the direction.
