AI Technical Summary

Benefits of technology

In one embodiment, the attachment member is rotatably mounted to the interior portion of the aft skirt. In another embodiment, the attachment member is movably mounted to the interior portion of the aft skirt and the system further comprises a control system to control movement of the attachment member to move the attachment member and thereby position the experiment outside the interior portion of the aft skirt.
In one embodiment, the experiment may be an experimental control surface. In this embodiment, the control system provides steering control of the attachment to thereby steer the experiment while positioned outside the interior portion of the aft skirt. In this embodiment, the system may also comprise a sensor associated with the experiment to generate sensor data and a data storage unit to store the generated sensor data.

Problems solved by technology

The transportation of cargo to space is expensive.
The problem is the cost of the individual operations required to transport cargo to orbit.
The traditional approach to manifesting of space launch systems has been hardware intensive, safety driven and long duration scheduling activities.
Many previous space launch patents in prior art discuss reusable features, but none talk about external payloads designed to permit the testing of the materials required.
U.S. Pat. No. 5,133,517 to Ware, issued on Jul. 28, 1992, uses an access door on the external tank, but fails to associate it to any exterior tests designed to provide samples for thermal protection system (TPS) analysis in the patent.
This involves altering the space shuttle mission trajectory, the salvage of the ET in orbit, a space walk by an astronaut for removal of the TPS samples from the ET, the restowing of the samples aboard a reusable segment of the vehicle and the proper disposal of the ET, which involves significant-additional effort and expense.
The Express Pallet does not address either cycle through the atmosphere, however.
Astrocourier (USA) addresses a similar commercial market, but also does not offer either cycle through the atmosphere, however.

experiment integration facilities

Integration facilities required by experiment support crews vary on a case-by-case basis on other reusable launch vehicles. As a baseline approach, the example. Kistler K-1 will set aside space in its vehicle processing facility (VPF) for use by the experiment's support crew as required. Kistler's K-1 example approach to SLI experiments is to integrate them as part of the normal maintenance and refurbishment process of the K-1 stages.

Therefore, placing the experimenter's support facilities in the Vehicle Processing Facility (VPF) will facilitate experiment integration into the K-1, which is refurbished and maintained in the same room. If required, Kistler can segregate the experimenter's area within the VPF, or provide a separate facility outside the VPF for use by experimenters. If clean facilities are required, Kistler can also provide the experiment support crew with a payload station in its PPF. The availability of the payload station is subject to coordination with Kistler's...

example 1

Passive Experiment Mounting Footprints

Six footprints are available to mount Passive Experiments on the outside of the K-1 Orbital Vehicle (OV). These footprints are attached to the exterior of the vehicle. Kistler's approach for passive experiments is to replace existing K-1 hardware (access panels, doors, tile, or blanket parts) with experiments mounted on Carrier Plates or bonded directly to the K-1 structure.

Passive Stowage with Active Re-Entry Environment Exposure

Commercial service includes the stowage of an experiment in the aft flare volume of the launch vehicle out of the re-entry slip stream and the ability to introduce the movable arm tip upon command or other control into the re-entry slip stream during the re-entry phase of the re-entry trajectory.

Abstract

An experiment system with six different re-entry experiment locations for testing high temperature re-entry materials, creating new thermal protection systems, proving innovative new concepts for spacecraft exterior surfaces and the incremental development of next generation aerospace materials. A commercial transportation system to and from orbit provides a 24-hour return cycle for the experiments on a surface actually re-entering the earth's atmosphere. Now using existing doors, hatches and other points on the reusable launch vehicle's exterior, the actual re-entry environment is experienced by test specimens with quick turn around for a wide variety of different re-entry temperatures ranges for broad testing and development purposes. The reusable launch vehicle launches, remains in orbit for 24 hours and returns to provide an actual test environment for the exterior experiment system.
