Z-pinch and Dense Plasma Focus (DPF) are two promising techniques for bringing fusion power to the field of in-space propulsion. A design team comprising of engineers and scientists from UAHuntsville, NASA's George C. Marshall Space Flight Center and the University of Wisconsin developed concept vehicles for a crewed round trip mission to Mars and an interstellar precursor mission. Outlined in this paper are vehicle concepts, complete with conceptual analysis of the mission profile, operations, structural and thermal analysis and power/avionics design. Additionally engineering design of the thruster itself is included. The design efforts adds greatly to the fidelity of estimates for power density (alpha) and overall performance for these thruster concepts.

“…This concept was developed out of research into pulsed power that resulted in the capability to produce very large electrical energy outputs, measured in mega-joules over nano-second pulses at powers in the hundreds of terrawatts. Recently, SNL's Z accelerator produced 1.8 megajoules in soft X-rays and delivered them at powers of up to 230 TW in 5 ns [9]. This capability has allowed Z-Pinch physicists at SNL to see if this capability is commercially viable for inertial fusion energy development.…”

Buckling of Stiffened Thin-Walled Truncated Cones Subjected to External Pressure

2007

View full text Add to dashboard Cite

The results of external air pressure buckling tests of thin-walled, truncated conical steel shells are presented, along with a description of the equipment developed for the testing program. The testing was conducted in support of Sandia National Laboratories Z-Pinch Inertial Fusion Energy Proof-of-Principle power plant design. Optimized stiffening ring locations were determined by using the finite element method, and were then tested, indicating an experimental improvement in initial buckling pressure of more than 300% over the unstiffened cone. An analytical method of determining buckling pressures of stiffened conical shells is also presented, based on the method of the equivalent cylindrical shell. The results of the analytical method agreed very closely to the finite element method for the stiffened cones, but are 20-40% higher than the experimental results.
