Yes, it's paywalled, but when sci-hub is working you may be able to get
it there. It's whack-a-mole with Springer's agents killing servers from

As often happens, while searching on another subject, I came upon this excellent paper from the Journal of Propulsion and Power on Advanced Rocket Nozzles, including altitude compensating nozzles.
Some interesting nozzles are in the paper:
RD-0120 Jettisonable Nozzle Insert for Improved Low Altitude Operation (actually proceeded to hot fire testing, noted here on ARocket previously)
Aerospike and Expansion-Deflection Nozzles (seen many times before)
Dual Throat and Dual Expander Nozzles (some interesting concepts)
Advanced Rocket Nozzles
Hagemann, Van Nguyen, and Dumnov
