Task 510: EP04 Analysis Reproduction Expansion
Status: DONE
Summary
Added 11 reproduction tests expanding EP04 coverage from 13 to 24 tests, pinning Uranus departure parameters, plasmoid momentum perturbation, and fleet intercept scenarios.
Tests Added
Uranus departure (4 tests)
- Titania escape ΔV = 1.510 km/s
- Escape velocity at Titania orbit = 5.156 km/s
- Titania circular velocity = 3.646 km/s
- Acceleration at full mass = 0.1327 m/s² (consistent with brachistochrone)
Plasmoid momentum perturbation (4 tests)
- 3 scenarios: nominal, enhanced, extreme
- Nominal velocity perturbation negligible (< 1e-12 m/s)
- All scenarios: correction-to-orbital ratio << 1
- Force increases monotonically: nominal < enhanced < extreme
Fleet intercept (3 tests)
- Arrival time at Titania = 9.7 hours
- 5 fleet ships
- Saturn-Uranus distance scenario at 1,438,930,000 km
Impact
EP04 was the least-covered episode in reproduction tests (13 tests). Now at 24 tests, on par with other episodes. Pins plasmoid momentum perturbation values that confirm momentum effects are negligible.
