SUMMARY

The discussion focuses on the force generated by small atomic bombs used in nuclear pulsed propulsion, specifically referencing a pressure of 50,000 PSI as noted in Wikipedia. The primary concern highlighted is the excessive thrust and acceleration produced by these engines, which poses significant challenges for spacecraft design. A minimum ship mass of 300 tons is suggested to ensure survivable acceleration for crew members.

PREREQUISITES
  • Understanding of nuclear propulsion concepts
  • Familiarity with pressure measurement units (PSI)
  • Knowledge of spacecraft design principles
  • Basic principles of thrust and acceleration in physics
NEXT STEPS
  • Research the engineering challenges of nuclear pulsed propulsion systems
  • Explore the implications of thrust-to-weight ratios in spacecraft design
  • Study the historical context and designs of nuclear pulse propulsion vehicles
  • Investigate safety measures and survivability in high-acceleration environments
USEFUL FOR

Aerospace engineers, physicists, and anyone interested in advanced propulsion systems and the challenges of nuclear propulsion technology.

Hey there...

for backround see the last post/.

Does anyone know the force (PSI) of a samml atom bomb such as the type used in nuclear pulsed propultion. ??

thanks a lot

Engineering news on Phys.org
Wikopedia has a lot of info. The one pressure number it gives is 50,000 psi.

Too much thrust (therefore too much acceleration) is of course the main problem with these types of engines. The smallest ship wikopedia says was conceived would need to be be 300 tons to have a survivable acceleration.
