Orbital Sea
Applied rotational physics for aerospace and defense
Research and development in propellantless propulsion, momentum-exchange systems, and silent drive technologies.
BACKGROUND AND VISION
Orbital Sea is an independent research initiative focused on applied rotational physics for aerospace and defense applications. Current work is led by Wilter Franceschi (Brazilian national, permanent resident of Canada) and is being conducted in preparation for formal establishment of a U.S. entity.
The program develops propellantless propulsion concepts, momentum-exchange architectures, and silent drive systems that are explicitly structured for future compliance with U.S. export-control regulations (ITAR/EAR). Public disclosure is limited to non-controlled, releasable information only; all sensitive technical data will be protected under U.S. jurisdiction upon entity formation.
Selected technologies are being matured with the objective of supporting U.S. government and approved commercial programs. In parallel, Orbital Sea maintains a commitment to open scientific education by publishing non-sensitive experimental results and foundational physics demonstrations.
PROJECTS
ITAR Compliance note
The information shared in this Projects section is limited to non-controlled, publicly disclosable aspects of our research. Orbital Sea adheres strictly to U.S. export control regulations, including ITAR (22 CFR Parts 120-130). Detailed technical data on sensitive aerospace and defense technologies is restricted and reviewed on a case-by-case basis. For inquiries, contact us via the protected email above.Orbital Conveyor Belt (OCB)
Propellantless cargo transfer architecture using momentum-exchange between co-orbital satellites. Payloads are handed off via low-Δv electric thruster or contactless (e.g., magnetic/electrostatic) transfer nodes. System scales with node count; net propellant consumption approaches zero in closed-loop configurations. Suitable for cislunar and GEO logistics.
Gyroscopic Gun (GG)
Electric sling-effect launcher converting sustained torque and multiple revolutions into linear projectile velocity. Eliminates chemical propellants and barrel wear typical of conventional guns while managing reaction forces through the rotating mechanism. Inherent gyroscopic stabilization, silent operation, and scalable muzzle energy. Applicable to small-arms, counter-UAS, and space-based kinetic systems.
Sling Propulsion Transit Network (SPTN)
Surface infrastructure concept using rotating electric launchers and passive aerodynamic or magnetic catchers to transfer kinetic energy to reusable vehicles. Enables high-speed, low-energy point-to-point transport on Earth and airless bodies with minimal continuous infrastructure.
Not publicly releasable (ITAR)
Vortex Sigil (VS)
Silent, pump-less propulsion for submersible platforms using rim-driven magneto-hydrodynamic and/or boundary-layer control principles. Eliminates cavitation and mechanical noise signatures.
Not publicly releasable (ITAR)
FOUNDER
Wilter Franceschi is the founder of Orbital Sea. As a civilian federal technical specialist assigned to the Brazilian Navy, he held a sensitive position with direct responsibility for maintenance, calibration, and operation of ITAR-equivalent controlled systems including naval radars, inertial navigation (gyroscopes), AIS, and military-grade GPS receivers. Since concluding that assignment he has worked as a full-stack software engineer while independently advancing a 20-year research program in applied rotational physics (Anglemetric Theory). All current aerospace and defense inventions are being developed explicitly for future U.S. incorporation and compliance with ITAR/EAR. He follows a strictly experimental approach guided by Richard Feynman’s principle: “If it doesn’t agree with experiment, it’s wrong.”
