XB-58 Pods

Mar 062021

From well before the B-58 program began, the Convair designers intended for their four-engined supersonic bomber to have a relatively gigantic pod underneath containing fuel and a nuke. The illustration below shows an early B-58 concept with the outboard engine nacelles located above the wing, together with a collection of potential bomb/fuel pods. “Freefall” contains an H-bomb; “Ferret” is electronic intelligence gathering; photo recon is obvious; and PPB is… hmmm. Note that none of these seem to have rockets in the tail, the ferret and photo recon pods doubtless were intended to return with the aircraft rather than be dropped.

Boost-phase interceptor

Mar 052021

An Aerojet concept for a boost-phase ICBM interceptor.

This would be a space-based anti-missile system composed of two high thrust solid rocket motors and a kill vehicle composed of a substantial set of optics, some impressive late 1980’s computers and most likely a hydrazine monoprop divert system. The missile would be meant to physically impact an ICBM while still being lofted by the first stage; this is an bigger, slower and brighter target than the later, faster, smaller stages and warheads, but you have to be *fast* to reach out and tag a missile in the first moments of flight.

A recent crowdfunding success

APR Patrons and Subscribers today helped crowdfund the purchase of a Boeing blueprint, an inboard profile diagram of the 2707-300 SST. An overly expensive item became reasonably affordable, and will be provided to each of the funders as high resolution scans in full color (and cleaned-up grayscale).

If you’d like to be involved in helping to preserve this sort of aerospace rarity, consider singing up for the Aerospace Projects Review Patreon or the Monthly Historical Documents Program.

Fleet Ballistic Missiles

From Polaris through Poseidon to Trident D-5:

Every one of those was proposed for alternate roles, from truck-towed and truck-launched land based strike missiles to air-launched and ground-launched satellite boosting systems. And they very likely *could* have done that. But they are just not really well suited for any role but sea launched ballistic missile due to the somewhat tricky propellants they use… high energy propellants so they can function adequately while still being able to fit in a small submarine. But for above-ground systems, they’d be somewhat dubious. The environment within a submarine is pretty consistent. For a missile stored in a warehouse and then hauled aloft by an airplane? The thermal and vibration environments will be highly variable.

Zenith Star Booster

This photo has popped up online before, but usually in pretty crummy resolution. It’s taken from “Aerojet – The Creative Company” and shows a mockup for a Titan-derived first stage booster rocket. It has double the engines of the standard Titan core stage, either two or four engines depending on how you want to count the LR-87 engines (one set of turbopumps, two combustion chambers) married to a 15-foot diameter core. This is described as a booster designed to loft the Zenith Star space-based laser weapon test system (the ZS was described and illustrated in US Spacecraft Projects #1). Documentation on this specific booster has always been somewhat lacking, though there have been quite a number of Large Diameter Core Titans designed by Aerojet and Martin over the years.

Boeing RC-1

A video about the Boeing Resource Carrier designed to fly oil from far northern Canadian sites to ports. One wonders if this concept could be employed today to take the place of the recently cancelled Keystone pipeline…

More about the RC-1 is available in US Transport Projects #5.

Nuclear Princess Model

Feb 192021

Recently for sale on ebay was a display model of the Saro “Princess” turboprop flying boat, as Convair planned to modify it into a nuclear-powered research prototype. This late 50’s design was ballsy if nothing else: a nuclear reactor would be installed within the fuselage, providing superheated air from the reactor to the inboard above-wing modified turboprops. Unlike the NB-36H, this aircraft would have been actually powered by the reactor.

A description of the concept was written up HERE. A set of detailed diagrams are available as Air Drawing 8.

Mercury Capsule Art

Two pieces of (presumably McDonnell Aircraft) artwork depicting the Mercury capsule:

These were procured from eBay thanks to the contributions of Patrons and subscribers. They have been made available at 300 DPI to all $4/month patrons/subscribers in the 2021-02 APR Extras folder at Dropbox, and at 600 dpi directly to all patrons/subscribers at more than $10/month. If you would like to help fund the acquisition and preservation of such things, along with getting high quality scans for yourself, please consider signing on either for the APR Patreon or the APR Monthly Historical Documents Program.
