DARPA Scraps Plan To Launch Small Sats from F-15 Fighter Jet
ALASA (Airborne Launch Assist Space Access) was a program to develop a launch vehicle that could be carried aloft by an F-15, with an orbital payload of around 45 kilograms. The design detail that was supposed to make ALASA work was what killed it: the propellant.
ALASA was to use liquid rocket engines. Nothing new there. The propellant combination was acetylene and nitrous oxide; that’s kinda new. But the Really New part of the design was that the two propellants were to be pre-mixed, meaning that the vehicle required only a single tank and simpler plumbing. Pre-mixing fuel and oxidizer is always a tricky proposition, but it has been successfully demonstrated from time to time. But here, in several tests the propellant simply exploded. This should not be overly surprising… acetylene is one of those unstable chemicals that will on occasion blow itself to bits just because it’s cranky. Mixing it with an oxidizer is just asking for trouble.
DARPA seems to have bailed on the launcher program, but is continuing to try to develop the propellant (called NA-7). Tricky though it may be, if it can be reliably stabilized there are undoubtedly vehicle designs that could effectively utilize it.
The ALASA vehicle made another unusual design choice: the rocket engines were near the front, not at the back. The reason for this: the trailing propellant tank could be dropped as a stage, but leave the engines in place. This would theoretically make the vehicle lighter, at the risk of having hot rocket exhaust scraping down the sides of the tank.

Not exactly a “PDF” review, but this should be of interest to many here: “Missiles & Rockets” magazine, a weekly periodical published from 1958 into 1968, was much like Aviation Week except with a more specific focus. And it has been made available on archive.org. I’ve found the search function to be somewhat ineffective, but the system allows for fairly straightforward navigation along with easy downloading of individual pages as high-rez JPEGs. The collection is not complete, sadly; it doesn’t look like it’s being completed, but there are nevertheless a fair number of issues available.

A three stage vehicle to transport 10 passengers to space stations and the like. I’ve recently come into possession of a whole bunch of reports on the Reusable Aerospace Passenger Transport and Reusable Orbital Transport programs; at some point these might make the makings of an APR article.
The third stage bears a vague similarity to the Boeing Dyna Soar in configuration, but is an entirely different vehicle. This concept helped set the course towards the Space Shuttle.

In the last few days a stash of Boeing hypersonic reports and diagrams were sold on ebay. I put in good bids, but got beat *bad* and by a number of bidders. If anyone knows who scored these, I’d sure like to be put in touch with ’em.

The image quality is admittedly terrible (being a scan of a print of a microfilm), but this might be of interest… a piece of NASA art circa 1963 depicting the Saturn V with an S-N third stage rather than an S-IVb third stage. The S-N was not a fixed design, but varied over the years; here, it was a fairly stubby stage ten meters in diameter, same as the S-IC and S-II stage. The S-N would vary in diameter and length from design to design, but one common element was the use of a single NERVA solid-core nuclear thermal rocket engine. As shown here, the distance from the nuclear rocket to the Apollo capsule up front just isn’t terribly far; consequently, this depicted a design with extraordinary levels of shielding, or depicted an unmanned Apollo (but then, why the abort tower), or it was just artistic license.

Boeing art from the late 1970s depicting the construction of a base in low Earth orbit, which in turn would be used to construct components of solar power satellites, which would then be slowly boosted to geosynchronous using electric propulsion. Even though the base would be dwarfed by the SPS itself, the base was monumental in scale compared to any other manned space facility proposed before or since.
The artwork (scanned from a brochure that was folded down the middle, thus there’s a half-repaired fold line) depicts not only a Space Shuttle orbiter, but also the second stage of a ballistically recoverable Heavy Lift Launch Vehicle.
I have posted the full-rez version at the APR Patreon Extras Dropbox folder for 2015-08 (while it’s 2015-09 now, the file began the process of uploading at 11:59 PM by my watch, so…). If interested, please check out the APR Patreon and consider joining. Lots of benefits!
