The Dual‑Ring Superconducting Artificial‑Gravity Habitat is a counter‑rotating, magnetically levitated deep‑space habitation architecture designed to provide long‑duration artificial gravity without the gyroscopic penalties of single‑ring centrifuges. The system consists of two concentric toroidal rings: an outer habitation ring with a 100‑metre diameter delivering 0.8 g at a rotation rate of 3.78 RPM,
The Griffiths Free-Flying EVA Logistics Sled (NGLS) is a purpose-built EVA logistics vehicle designed to solve a capability gap that traditional astronaut maneuvering units were never intended to address. Systems like SAFER and the historical MMU were built for personal mobility and emergency return, not for transporting heavy equipment, structural components,
The H2 EM Aero Engine is a field governed, ammonia fuelled hydrogen combustion architecture designed for piston propeller aircraft. It eliminates the storage problem that has made hydrogen impractical for general aviation by cracking ammonia on demand and producing only the hydrogen required for the next combustion cycle. No hydrogen is ever stored on board.
Beyond Whittle proposes a replacement architecture for aviation combustion: an electromagnetic field‑governed reaction kernel that stabilises hydrogen combustion without swirl, without geometry‑anchored flameholding, and without the thermoacoustic and flashback instabilities that make hydrogen fundamentally incompatible with Whittle’s 1940s combustor topology. As the document states, “hydrogen’s ultra‑high flame speed,
GRFF v8.0 — the Griffiths Reactive‑Field Framework — is a four‑layer, five‑technology active/passive defence architecture engineered for long‑duration deep‑space habitats operating beyond Earth’s magnetosphere. It addresses the full spectrum of deep‑space hazards: hypervelocity micro‑debris, micrometeoroids, charged‑particle flux, dust clouds, and solar‑particle events. Deep‑space structures face “persistent,
This project presents a bio-mimetic wing system designed for human-scale flight, modeled with 1mm precision in Onshape. Unlike rigid traditional wings, this design utilizes a series of "human feathers" that mimic the skeletal structure and plumage of large birds of prey.
Key Technical Features:
Parametric Design: Utilizing Onshape’s variable studios,
Subtitle: A Modular Approach to Sustainable Regional Aviation
Regional aviation is essential for connectivity, yet short-haul flights are disproportionately carbon-intensive. Our hybrid-electric propulsion system offers a practical, scalable solution to reduce emissions while maintaining operational efficiency.
The Challenge
Short-haul flights produce high emissions per passenger.
Modern aerospace faces a fundamental propulsion paradox: systems optimized for atmospheric flight are poorly suited for vacuum operations, and vice versa. Rockets burn through propellant at enormous cost; electric thrusters offer efficiency but negligible thrust. The result is a fragmented launch-to-orbit pipeline that drives up mission cost, mass, and complexity. The PEMMA Drive,
The HIDF‑CFT is an experimental human‑powered force‑transmission system based on a dorsal trunk support point, designed to explore how coordinated activation of the arms, legs, and torso may influence mechanical efficiency. The concept reinterprets the classical ornithopter principle by shifting the external fulcrum from the ventral side of the body—as seen in historical designs—to the posterior side,
