Here at RPI there is research going on in the area. Based on Henry Spencer's post, I thought I'd comment. >Could you use air as propellant? Maybe. A reflective plate with parabolic > hollows carved in it will focus an incoming pulse (provided it's pretty much > perpendicular) to a set of hot spots near the plate, where the air will > break down and absorb the beam, producing miniature thermal explosions > that will push on the plate. It's been tried in the lab; it works. Yes, that is what the RPI concept does, it uses Air as a propellent in the lower atmosphere. Not sure what it uses in a vacumn. > Could you build one today?

Well, I believe in the summer of '91, they are planning on testing a portion of the full scale engine using a laser. It has been tested on smaller scales as Henry suggests. Also, they have done a lot of the aerodynamic testing here at RPI at our Hypersonic Shock Tunnel. As for Person-Rating the system, the current plan that Leik Myrabo (the professor heading up the project) has, was to use a module based on either the Gemini Capsule, or on the extended 5 person Apollo Capsule. (Yes, I know and I am sure he knows the plans are lost etc...). But, he firmly believes that the lifting capability is within the realm of possibility. Further possibilities, and I believe what he thinks is the most economical is to use space-based lasers feed from a Solar Power Satellite. You could also use the same system to power airliners. (We discussed once (very informally) the idea of building 'flying saucer' fighters that could manevour with up to 30g manevours for a split second (within limits of the human body since the period of acceleration is so brief). The problem at that point, is tracking. Gets to be a pain with the atmosphere and most feedback systems.) ------------------------------ Date: 24 Nov 90 22:17:16 GMT From: dog.ee.lbl.gov!ncis.tis.llnl.gov!blackbird!tkelso@ucsd.edu (TS Kelso) Subject: NASA Prediction Bulletins, Part 1 The most current orbital elements from the NASA Prediction Bulletins are carried on the Celestial BBS, (513) 427-0674, and are updated several times weekly.

The New England paper, the closest metropolitan paper to the former Perkin-Elmer plant where the mirror was ground, says that to some extent the failure to detect a flaw polished into the primary mirror in 1980 is a product of the same management climate that led to the fatal explosion of the space shuttle Challenger. The paper says that conditions then discouraged engineers from bringing potential problems to their superiors at NASA and at Perkin-Elmer, in Danbury. The paper quotes an investigation team member, John Mangus, as saying "the culture has to be encouraged where you don't shoot the messenger. People don't like bad news, but what they like worse is not to be told about the problems. I know it has occurred on many of NASA's projects." ___ _____ ___ /_ /| /____/ \ /_ /| | | | | __ \ /| | | | Ron Baalke | baalke@mars.jpl.nasa.gov ___| | | | |__) |/ | | |___ Jet Propulsion Lab | baalke@jems.jpl.nasa.gov /___| | | | ___/ | |/__ /| M/S 301-355 | |_____|/ |_|/ |_____|/ Pasadena, CA 91109 | ------------------------------ End of SPACE Digest V12 #595 *******************
