What is CID™? The Centrifugal Impulse Drive (CID™) is a propellantless propulsion system that generates thrust through the interaction of magnetic fields and centrifugal forces. Unlike traditional propulsion systems, it doesn't need to expel mass to create momentum.
Complete Technical Breakdown of CID Operation and Physics Validation
-------------------
Core System Parameters:
- Magnets: 1" × 1" × 0.5" Nd grade 52
- Rotors: 2x counter-rotating, 6" diameter
- Speed: 150 RPM (ω = 15.71 rad/s)
- 4 magnets per rotor
-------------------
Force Analysis:
F_centrifugal = mr𝜔² per magnet:
- Single magnet: 1.14 N
- Per rotor (4 magnets): 4.56 N
2-millisecond contact when the rotor magnet is fully extended.
Actual thrust 400 to 500 mN
-------------------
Operating Principle:
1. Magnetic-Centrifugal Interaction:
- Magnets held by stator magnetic repulsion
- At gap: magnetic force → 0
- Pure centrifugal throw (20mm)
- Magnetic recapture post-gap
2. Counter-Rotation Dynamics:
- Cancels gyroscopic precession
- Doubles effective thrust
- Maintains angular momentum balance
-------------------
Physics Validation:
Newton's Laws Compliance:
1. First Law: System equilibrium maintained
2. Second Law: F = ma strictly followed
3. Third Law: Action-reaction preserved
- Outward magnet motion (action)
- Inward hub force (reaction)
Conservation Laws:
- Momentum: Balanced through counter-rotation
- Energy: Rotational → Linear conversion
- Angular Momentum: Preserved via symmetry
-------------------
Energy Chain:
Rotational → Magnetic Potential → Kinetic → Thrust
Momentum Analysis:
Δp = mv = m(rω)
- Per magnet: 0.0725 kg⋅m/s
- System total: 0.5800 kg⋅m/s
-------------------
Key Innovation:
Internal force redistribution while maintaining conservation laws through:
1. Precise gap timing
2. Counter-rotating architecture
3. Synchronized magnet release/capture
