H2EM Jet Engine: Electromagnetic Field Hydrogen Combustion Aviation Turbine

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,

Human Integrated Dorsal Frame – Coordinated Force Transmission (HIDF‑CFT)

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,

Hybrid-Electric Propulsion for Regional Jets

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.

Hypersonic Launch - Maneuverable Hypersonic Interceptors Create a 1000km Diameter Protection Dome

The HVP-500 interceptor up to Mach 9 using the Green Launch Light-Gas Launch System and makes the Golden Dome Affordable.

The Green Launch’s HVP-500's interceptor has a 500 km range which allows for early, high speed, intercept compared to the more costly THAAD or Patriot systems with 150 km range at $12.6M, $4M cost respectively.

Integrated Active Empennage Architecture

What problem does the innovation solve?

Rear-mounted pusher-propeller aircraft typically suffer from a severe reduction in control authority at low airspeeds (such as during low-speed STOL operations or VTOL transition phases) because traditional tail surfaces rely on forward velocity to generate aerodynamic force. Mechanically, rear-propulsion architectures introduce massive Center of Gravity (CG) challenges;

Integrated Five-Technology, Four-Layer Active/Passive Defence Architecture for Deep-Space Habitats Including Governed Dust — A Reactive EM Field Architecture for Upstream Capture and Downstream Protection

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,

Layered Resilient Navigation System (L-RNS)

The Layered Resilient Navigation System (L-RNS) is a software-defined, sensor-fused PNT architecture designed to maintain accurate navigation continuity across the full spectrum of electronic warfare threats — from broadband jamming to precision spoofing — without dependency on any single signal source. L-RNS operates as a hierarchy of trust: under benign conditions, a multi-constellation,
