ISRO reference study
PSLV
polar and multi-orbit launch vehicle. Architecture: Four-stage solid/liquid vehicle with optional strap-on boosters.
Use in design studyAeroVectrix Study Notes
- PSLV is a reference case in mixed solid/liquid staging and mission reliability.
- AeroVectrix study focus: stage sequencing, upper-stage restart utility, strap-on variants, and rideshare mission design.
Working Model
Ascent
Mission begins with thrust-to-weight margin, guidance through dense atmosphere, max-Q load management, and staging when the lower stage has delivered useful impulse.
Staging
Separation events must protect vehicle attitude, avoid recontact, confirm engine start conditions, and preserve payload environment limits.
Mission Assurance
Public vehicle studies should track assumptions, review dates, risk areas, and unknowns rather than overclaim exact proprietary data.
