Cancelled Projects: SLOMAR
By Jos Heyman
(with some help from the correspondents of the Secretprojects forum)
In 1959 the US Air Force started the Space Logistics, Operations, Maintenance and Rescue (SLOMAR) study to generate preliminary designs of crewed space vehicles that could support manned military space stations.
SLOMAR was one of ten studies that were part of the USAF’s ‘Space Development Planning Study’ that also included studies covering, amongst others, satellite interception, global surveillance, strategic orbital systems (bombardment satellites), lunar operations, and recoverable orbital launch systems.
In November 1959 a Request for Proposals was issued and ten contractors responded. Of these only Lockheed, General Dynamics, Douglas, Martin and Norair (Northrop) received further funding in June 1960 to the sum of $ 120,000 each. This was to cover studies up to June 1961. It was soon obvious to the contractors that the funding was insufficient to study all areas concerned and each contractor emphasized some aspects only.

Martin suggested a lifting body vehicle with a span of 6.65 m and length of 9.40 m with room for a crew of five.

In spite of not receiving funding, McDonnell suggested its model 15 (?) whereas Bell studies its program 7069, whereas it has been suggested that North American also conducted privately funded SLOMAR studies.
Absent from this all was Boeing but that company was already involved in the development of the X-20 Dyna Soar spacecraft.
The contractors’ submission were evaluated and led to the conclusion that it was possible to have an operational system in use by 1968 for support to orbits up to 925 km and that more than one satellite at a time had to be supported during a mission to make the system cost effective (except for the space station). Furthermore it was clear that guidance of the vehicle was to be self contained and that the total capacity of the vehicles, crew plus passenger, was to be six.
These conclusions were passed on to the Lunar Expedition Project (LUNEX), a secret USAF proposal to put a man on the Moon by 1967 and that would employ a lifting body re-entry vehicle for a crew of three. These efforts were suspended when John Kennedy ordered NASA in May 1961 to get a man on the Moon before the end of the decade.

The Astrotug

Tugboat for Space: Spaceborne scientific laboratories and platforms for further exploration into space are an accepted concept based on established engineering techniques. Components would be fired  as individual units into space, on precalculated orbits, and there assembled. To solve the major problems of how men are to live and work in space during the assembly process. Lockheed has prepared a detailed engineering design of an astrotug – a manned vehicle housing a crew of two or three. Missile-launched, the astrotug will be capable of supporting its crew for a number of days in an environments of suitable atmosphere, and with provisions for illumination and adequate food and water.
The Lockheed astrotug is a completely independent working vehicle. Personnel need not leave it in space suits in order to work on the project of assembling the space station components. As shown in the diagram, the tug consists of two double-walled pressure vessels approximately 20 feet long overall and 9 feet inside diameter. Swivelling rocket nozzles are arranged for maneuvering. On the forward end, extending out are four mechanical manipulator arms with interchangeable "hands" for such specialized functions as gripping, welding, hammering, cutting, running screws, etc. "Hands" can be changed by remote control from the inside. Viewing ports provide uninterupted observation. Radar antennas, searchlights, and other equipment necessary to the tug's work are mounted externally. Main controls and instruments including radar, radio, infrared, computers and navigational consoles are duplicated in each of the two major compartments as a safety measure.
Men working in single units afloat in space suits would have little applicable force and could work for very limited periods of time. With the Lockheed astrotug, personnel could carry on the work in relative safety and comfort with maximum efficiency. A special reentry vehicle, separate from the astrotug, has been conceived for ferrying to and from earth. Tugs themselved would remain floating in orbit indefinately, being reprovisioned  and refurbished as fresh crews arrive in relief.

2.3 ORBITAL RENDEZVOUS
Work during this phase of the project was faced with many unknowns. Initially, a cursory study was made in the area of orbital mechanics to determine what precision was required from thrust control during orbital rendezvous and if there might be a mass trade-off between shock mitigation and thrust control equipment. Again, airframe manufacturers and other agencies contributed to this effort.
The findings are summarized below:
a. The planes of the orbits of the target and intercept vehicles must be within minutes of arc.
b. The orbits must be matched in shape, size, and orientation within minutes of arc and, at time and point of rendezvous, the vehicles come together within close proximity.
c. The vehicles must be closely "in phase'" to affect rendezvous.
d. The vehicles, in the case of earth orbit rendezvous, should avoid lengthy exposure to the lower Van Allen radiation belt.
e. To make a rendezvous possible, corrective vernier rockets will have to operate within extremely precise limitations of thrust and cut-off times to bring relative velocity within acceptable limits.
f.* It was determined that, if each vehicle's velocity vector does not intercept the other's center of gravity on rendezvous, there may be a tumbling problem after contact.
To hold the mass of the shock mitigation equipment to an acceptable percentage of total mass, relative velocities were not to be considered over 35 ft/sec.
Parameters forming the framework for orbital attachment concepts include the same values applied ia-paragraph 2. 1; therefore:
a. 4 "earth" g's max. safe deceleration.
b. 1.5 safety factor applied to deceleration.
c. Vehicle gross weight approximately 20 tons (earth weight).
2.4 EARTH MANEUVERS
In this area, many concepts were submitted. However, since the problem of return to earth and landing are under detailed study in the Air Force as a portion of the Dyna-Soar development, no attempt was made to list a framework for concept formulation concerned with earth maneuvers.
* Any gravitational attraction between two bodies can be discounted with regard to bringing or holding them together. Eg: it takes only 2 (10)-5 radians/sec. rotation about a common C.G. to make two bodies of 100 tons each (whose C.G. 's are 100 feet apart)to balance the gravitational force holding them together.
3. SCOPE OF CONCEPTS
As the project progressed, the concepts submitted were categorized as to earth allghtment or departure, (labeled E-1, E-2, etc.), orbital attachment (0-1. 0-2, etc.), and lunar alightment or departure (L-l, L-2, etc.). They were sub-categorized as logically as possible, as to their nature — mechanical, electro-mechanical, multi-strut, etc.
5. 1 CONCEPTS SUBMITTED
The appendix shows the concepts submitted in pictorial form. They are separated into the three major categories shown above. Class I illustrates earth alightment and departure, Class II orbital rendezvous, and Class III lunar alightment and departure.
The sixteen (16) [only 6  Orbitals] most promising concepts as selected by WADD, are listed below:
Class I – Earth Concepts
……..
Class II – Orbital
3. O-1 Attachment by tail-hook snag.
4. O-2 Attachment by self-guiding probe through hoop.
5. O-7 Attachment by mechanical grappling hook — close range,
6. O-8 Orbital attachment by self-guiding probe,
7. O-11 Long-range attachment by probe and drogue — heat or light sensitive,
8. O-15 Attachment by mechanical parallelogram grappler. [This is the only illustrated concept shown here that made it through.]

Class III – Lunar Concepts
……..
NOTE: The 34 concepts eliminated from further study by WADD were rejected on the basis of (a) insufficient anticipated reliability, (b) lack of
confidence In state-of-the-art advances in that area and, (c) in the case of bags, balloons, and parachutes, cognizance by other WADD Laboratories.

Preliminary Design Concepts
•    Bell Aerosystems Remora Capsule

 1960   REMORA Manned Space Manipulator    Bell Aerosystems (American)
The REMORA configuration (Figure 5-15) is a small, buoy-shaped capsule 6-feet high, 3-feet in diameter, and weighing 540 pounds (leaded). This concept, proposed shout 1960, permits one astronaut to function in space while protected from the space environment. The capsule is tethered by a cable that provides power and retrieval, if necessary, and allows a maneuvering radius of 1,000 feet. A tinted dome provides access to the capsule and allows 360deg visibility. The capsule is oriented by reaction jets and has an operating time of 4 hours (a function of its life support system).

REMORA
In the vacuum of outer space, Bell's Remora capsule could enable men to assemble, inspect, service and maintain satellites and space stations or shuttle men between space vehicles protected from the hazards of meteorites and radiation.
Taking its name from the fish which attaches itself to sharks, Remora is equipped with mechanical grappling arms by which it can attach itself to space stations and satellites. Inside the capsule the spaceman will have freedom to manipulate the arms to engage in assembly and maintenance activities.

Nonanthropomorphic maneuvering units.
As early as 1960, Bell Aircraft Corporation proposed the REMORA system, which combines direct and remote manipulation. The REMORA concept (see above) appears to offer several advantages. First, if necessary, it could be shielded to protect the extravehicular worker in zones of high radiation. Second, a variety of arms may be used, each designed to serve a special type of operation. For example, one pair of arms might be of the gauntlet type for use on jobs requiring delicate manipulation. One arm might hold and provide power for tools such as drills; other arms might simply hold the work, leaving the operator's gauntleted hands free for productive work. (Industrial engineers tell us that the "hold" operation is probably the greatest source of inefficiency in assembly and maintenance operations.) The possibilities are almost infinite. Third, REMORA is pressurized, requiring the operator to inflate his suit only in emergencies. This feature would greatly reduce fatigue and extend useful time of work.
