TNE Only: Solid Fuel Rockets

[snrdg082102]

Hello again everyone,

Book 2 Chapter 9 Sublight (Maneuver) Drives page 70 indicates that solid-fuel rockets with less than 500 kg of fuel mass suffer from inefficient fuel combustion.

Book 3 Chapter 9 Munitions B. Atmospheric Rockets and Missiles page 146 has what appears to be the same requirement for size efficiency.

Book 3 Chapter 9 Munitions C. Space Missiles page 146 indicates that the common thruster used is an EAPlaC solid-fuel rocket. There is no mention
that solid-fuel rockets with < 500 kg of fuel need to check for size efficiency.

Shouldn't space missiles using solid rocket fuel have the same requirements for size efficiency as does maneuver drives and atmospheric rockets or missiles?

Book 3 Chapter 9 Munitions B.7. is just referencing (and partially repeating) the Sublight Drive chapter. Book 3 Chapter 9 Munitions C.1. appears to summarize much of the same information, so I would apply the size inefficiency rule. This should be added to errata.

Evening from the Pacific Northwest of the US elbmc1969,

Book 3 Chapter 9 Munitions B.7. is just referencing (and partially repeating) the Sublight Drive chapter. Book 3 Chapter 9 Munitions C.1. appears to summarize much of the same information, so I would apply the size inefficiency rule. This should be added to errata.

Thank you for the reply which appears to support my conclusion that
a space missile using a SFR with less than 500 kg of fuel should follow the Size Efficiency Rule.
