Cancelled – May AIAA Social


The AIAA Houston summer kickoff / networking and social event scheduled tomorrow (Thur. May 16) at Nobi is cancelled.

Weather forecasts suggest heavy rain Thursday afternoon and evening in the Houston area, and a
flood watch is in effect Thur. May 16 1pm until Friday 7am.

Stay dry and stay safe – see y’all another time.

by May 17th

As a reminder, we have our section Social every third Thursday of the month.

We also have an upcoming virtual LunchnLearn with special guest Dr. Hashima Hasan.

Happening every Saturday: Join us via Zoom every Saturday for all things space, exploration, engineering,
and more!

“The Interstellar Ramjet: A Technical History”

In 1960 Robert Bussard published a solution to the mass ratio problem for interstellar flight. He laid out
the design of a starship that scooped interstellar hydrogen compressed it in a fusion reactor, extracted energy
and produced thrust. The process is similar to a terrestrial ramjet.
Bussard outlined the propulsion method, presented the equations of
motion and made general assessments of performance and
propulsion efficiency.

Sagan suggested magnetic ‘scoops’ for collecting working
matter from the interstellar medium. Fishback in 1969 calculated
important limitations on the ramjet magnetic intake and quantified
drag and radiation losses for the ramjet.
Fishback showed there was a limiting Lorentz factor for an
interstellar ramjet imposed by the material properties of the scoop

Tony Martin expanded Fishback study and made some
important observations. The main problem with the concept was
using proton-proton reactions for fusion, this proves very difficult.
In 1975 Dan Whitmire made progress towards solving the fusion reactor problem of the interstellar ramjet
by noting that one could use the CNO process rather than the PP mechanism as method of fusion operation.
Bond and Jackson suggested alternative ramjet operation using augmentation. An alternative to the
Bussard Ramjet was presented in 1977. The Laser Powered Interstellar Ramjet, LPIR. This vehicle uses a
solar system-based laser beaming power to a vehicle which scoops interstellar hydrogen and uses a linear
accelerator to boost the collected particle energy for propulsion bypassing fusion reactor problems.
