Boeing has been looking at several TSTO vehicles and has carried out extensive conceptual studies of advanced launch systems for some time. A good reference on this might be: "Comparison of Propulsion Options for Advanced Earth-To-Orbit (ETO) Applications (IAF-92- 0639)." by V.A. Weldon and L.E. Fink from Boeing. The paper describes a propane-fueled TSTO launch system claimed to achieve aircraft-like operational efficiencies without the problems associated with liquid hydrogen fuel. Basically, it's a high-speed airplane launching a Hermes-type spaceplane The design (the concept is also called "Beta") as laid out in the paper can launch at least 10,000 pounds into polar orbit, or 20,000 pounds to space station orbit including a crew of eight persons and life support. System design reliability is .9995. Beta is a 360-foot-long first stage powered by two large ramjets and 12 high- speed civil transport (HSCT) turbofans. A 108-foot- long reusable orbiter is trapeze-mounted in the belly of the first- stage aircraft, which also could accommodate a longer and heavy payload on an expendable second stage. To launch the orbital vehicle, the first stage takes off like a normal HSCT and accelerates to Mach 3. At that point the turbofans, modified to burn catalyzed JP-7, would shut off and the ramjets, would take over. At Mach 5.5 the orbiter or the ELV would swing out, ignite and proceed to orbit. Both vehicles would land like aircraft at the conclusion of their respective missions. Estimated total weight of the combined configuration at takeoff is about 1.5 M lbs, roughly equivalanet to a fully loaded An-225. The orbiter stages weighs about 400,Klbs including 335 Klbs of LOX and subcooled propane to power two 250 Klbs vacuum thrust rocket engines. Propellants would be stored at 91 degrees Kelvin, with the propane in a spherical tank mounted forward of the 15-by- 25-foot cargo bay and the two-seat orbiter crew station. LOX would be stored aft. Weldon and Fink claim the key to this design's success is the structurally efficient airframe and the compact tankage allowed by the high-density supercooled hydrocarbon fuel. The paper compares TSTO design to SSTO design. They conclude while a SSTO has a slightly lower recurring cost, a TSTO is easier, cheaper, and less risky to develop, simpler to build, has greater safety and mission versatility and doesn't carry the hard-to-handle and bulky hydrogen fuel. The conlcude "In conjunction with its major use of airplane type engines and fuel, as well as its inherent self- ferry capability, it is probably the system most likely to provide as close to airline-like operations as possible with a practical configuration, until a single stage airbreather/rocket concept can be shown to be operationally viable." >Is this really news? Does this threaten further work on DC-? Weldon and others at Boeing have been working on TSTO designs for some time. I expect this, or a similar concept (perhaps the HTHL SSTO they proposed for the SDIO SSTO first phase) is being re- examined as a basis for a bid on the first phase of SpaceLifter. Does it threaten DC-???. Possibly -- There is a set of on-going studies trying straighten out the government's future space transportation strategy. MDC and Boeing (as well as other firms) are providing data to a joint study team back in DC. There are various factions and options vying for attention -- including shuttle upgrades, shuttle replacement (what was called the "4-2-3" architecture), SpaceLifter, ELV upgrades, and various advanced vehicles (ALES, Beta, DC-??, NASP, FSTS, SSTOs of several types, etc.) NASA/DOD/DOT are trying to put together a coherent strategy for future US gov't space transportation systems, and trying to juggle near-term launch needs (like for DoD and NASA) against medium-term needs (including commercial considerations), and against the investment and risk of going to "leap frog" new technologies like SDIO/SSTO and NASP and Beta. It's a heck of a problem. The worst part of the problem isn't that there aren't promising ideas and concepts -- there are dozens of them -- but how they balance cost and risk versus real needs in the near term. They should have a draft report in mid-June, with a final report coming by the end of the fiscal year. ------------------------------------------------------------------ Wales Larrison Space Technology Investor --- Maximus 2.01wb ------------------------------ Date: Fri, 30 Apr 1993 18:18:04 GMT From: zellner@stsci.edu Subject: HST Servicing Mission Newsgroups: sci.space,sci.space.shuttle,sci.astro In article <1rrhlo$ajb@access.digex.net>, prb@access.digex.net (Pat) writes: > > After all the space walking, they are going to re-boost the HST's > orbit.

Putting a satellite as high as possible is one thing. Coming back to not only that altitude, but matching the position of it in its orbit on a subsequent mission is another thing. Any misalignment of the plane of the orbit during launch or being ahead or behind the target will require more fuel to adjust. This was considered in the original deployment. I agree though that the demands on the crew and complexity are stupendous. One has to admire how much they are trying to do. Wm.

The problem with your approach is they add up what you can reasonably claim as 'spin-offs', add up what's been spent on space, and then come back with something like, "You spent $X billion for that? Wouldn't it be better just to spend the money on direct research and forget all this space stuff? We could have got all that stuff a *lot* cheaper that way. Space is wasteful and inefficient."

This will be a follow on to our succesful deployment of a 20 kilometer tether on the March 29 flight of SEDS (Small Expendable Deployment System), which released an instrumented payload that reentered the earth's atmosphere and burned up over the west coast of Mexico. This time we want to make a payload that can be recovered. We want to build it from "off the shelf" technology so as to do this as quickly and inexpensively as possible. We want to be able to track the payload after it has deployed its parachute. An idea we have is to put the same kind of radio beacon on it that is used with SARSATs (Search and Rescue Satellites). It would turn on with the opening of the parachute and aid in tracking. These beacons are known in the marine industry as EPIRBs (Emergency Position Indicating Radio Beacon). They are rugged (they have to be to survive a ship wreck!) and cheap. We have several questions: 1. What is the world authority regulating the use of SARSAT beacons. Are there multiple authorites, i.e. military and civilian? 2. What are the regulations regarding the use of SARSAT signals. Can they be used for one of a kind situations with a long lead time of warning the relevant authorities, or are they strictly reserved for life threatening emergencies? 3. What is the coverage of SARSATS? Are they in LEO with only intermittant coverage of a fixed position on the earth, or are they in geosynchronous orbit? 4. Is there an industry organization governing the use and manufacture of these transponders?

Doing this in anything like reasonable time would require more propulsion capability than we can manage. You would have to boost to Pluto and then slow back down. You could do something like a Hohman orbit, but I think that would take ridiculous amounts of time (my Rubber Bible is at home). -- "Insisting on perfect safety is for people who don't have the balls to live in the real world." -- Mary Shafer, NASA Ames Dryden ------------------------------------------------------------------------------ Fred.McCall@dseg.ti.com - I don't speak for others and they don't speak for me. ------------------------------ Date: Fri, 30 Apr 1993 20:02:56 GMT From: Josh Hopkins Subject: Space Manuevering Tug (was HST servicing mission_) Newsgroups: sci.space prb@access.digex.net (Pat) writes: >Given that what i described for the HST seemed to be the SMT, and given >the mass amrgins on the discovery mission is tight enough that spacewalking >has to be carefully constrained.....

Pat, this would be slower, more expensive and worse. Slower: The shuttle mission is scheduled to go up in December. That's less than eight months away. There is no way you could build new hardware, retrain and reschedule the EVA's in that time. More Expensive: Your proposal still requires the shuttle to do everything it was going to do execpt fire the OMS. In addition, you've added significant extra cost for a new piece of complex hardware. According to a GAO report on the OMV I have before me, there are only two currently planned missions that could use such a vehicle -- HST and AXAF. Since AXAF has since been scaled back and HST can rely on the shuttle, there doesn't seem to be any need for your vehicle. -- Josh Hopkins jbh55289@uxa.cso.uiuc.edu "Find a way or make one." -attributed to Hannibal ------------------------------ Date: 30 Apr 1993 19:27:24 GMT From: William F Brown Subject: Space spinn offs Newsgroups: sci.space,sci.astro I just wanted to point out, that Teflon wasn't from the space program.
