I could see literally none. Why it may need glide? It was supposed to have parawing for controlled descent.
Orionblamblam said:Giving the re-entry vehicle a decent L/D would give it decent cross-range capability. A parawing would not. Cross range would probably be important for a vehicle like this with limited on-orbit duration,since you'd want to recover the pilot and the onboard systems within the CONUS.
Dilandu said:But it would led to great increase of complication (and inevitably - mass) of the spacecraft, since it would be subjected by lengthier thermal & dynamic stresses during re-entry. For the spacecraft, which was designed to be as light and simple as possible - basically a space F-5 light fighter - it would essentially be way into nothing.
Orionblamblam said:Tradeoffs. If you're happy with your space fighter splashing down in the ocean, with all the logistical headaches that come with it, then by all mens use a low L/D capsule. Or if you are fine with leaving your spaceraft and pilot in orbit for an extra day or so so his low L/D craft can make it to a CONUS base, then, fine. otherwise, crossrange is your friend.
Odd that you should pick that example, because the F-16 was a short-range lightweight fighter whose only function was to dart in the sky and fire two wingtip Sidewinders. Then it got improved into something actually useful.Dilandu said:It's like designing a short-range lightweight point-defense interceptor, which only function is to dart in the sky and shot two wingtip "Sidewinder"s at designated target under ground radar control, and then suggest that it would be better if it have the same range as F-16. Of course it would be better, but the tradeoff would be severe, and your lightweight point-defense interceptor would turn into something strange; medium-weight long-range fighter without serious avionic & with very limited armament. At this point, it would be simpler to just buy F-16 (or Mig-29 from Mother Russia)

That sounds quite awesome. Do we have a good idea of the concept of operations of such?
The vehicle was based on SWERVE. Same strakes as SWERVE.
some additional information I found, not sure if it's been posted already. It mentions that the wind tunnel model of the Spacecruser had small highly swept wings or strakes. I presume they were on the sides of the craft, but surely there must be some sort of strake above and below as well. If so, where would the upper one have been placed? With the pilot right at the back and a hatch over his head for him to look out of the craft, any dorsal strake would be totally in the way.
Please excuse my ignorance, but by which means does the "Space Cruiser" engage/destroy the said satellite archiepeppe?Matej said:Nice drawings. In this case I realized, how complicated is it to have human aboard. Thanks God for progress in technology.
You're right Matej, especially if we take into account that "Space Cruiser" (despite to its so magnificient name) was the closest thing to a "space fighter" ever conceived until now.
It was to be launched by a submarine, through a SLBM, instead of the MIRVs onboard.
High maneuverability, due to its 17 small engines, across 2/3 orbits of lifeflight.
No pressurized section, so the crewman has to wear pressurized suit all over the time. This allows to save weight and to be less sensible to damages in an eventual battle.
The high gees ballistic reentry was to be performed "a la ICMB" pointing nose down. After reentry a "Rogallo wing" was to be deployed, with landing skids, to achive landing or splashdown. In this way it was possibile to have a flexible, high covert (due to its launch nature) and even cheap military space vehicle.
Love that side-mount TAV.What is all my hard work on the SRI Space Cruiser to go un-utilized?

Now…could saddle-tank type inflatable air bladder/ballutes to either side of Space Cruiser give you better cross-range at speed than simply popping a rogallo wing subsonic.
You could launch out of a silo still.
The guy behind the Space Cruiser has a few patents on it:

Search and read the full text of patents from around the world with Google Patents, and find prior art in our index of non-patent literature.patents.google.com
My recollection is that there were more than 2 patents and at least one described the SSBN launch concept, but I may be mistaken.
As the 2030s approach, focusing on "financialized" fringe incremental current upgrades are not going to get one air superiority let alone space dominance. Space is the race and the place. 60-70-80k ft is just the takeoff airfield for not just a few boutique systems if ur not to be left behind.
