Shuttle Core Storage Box
A Shuttle Core Storage Box is a container designed to securely hold and transport solid rocket boosters (SRBs) or, more specifically, the core components of SRBs used in space launch vehicles. These boxes are critical for the handling and maintenance of reusable SRBs, notably those employed by the Space Shuttle program and, currently, by the Space Launch System (SLS).
Material:
The boxes are constructed from robust materials capable of withstanding significant weight and environmental stresses. Common materials include:
- High-Strength Steel: Provides structural integrity and protection against impact.
- Composite Materials: Increasingly used for weight reduction while maintaining strength, particularly in newer designs.
- Insulating Materials: Incorporated to protect sensitive components from temperature fluctuations.
- Protective Coatings: Applied to prevent corrosion and damage during handling and storage.
Purpose:
The primary purposes of a Shuttle Core Storage Box are:
- Protection: Safeguarding the SRB core from physical damage during transport, handling, and long-term storage.
- Containment: Preventing the release of hazardous materials potentially present within the SRB core (e.g., propellant residue).
- Environmental Control: Maintaining a stable environment to prevent degradation of components.
- Facilitating Maintenance: Providing a secure platform for inspection, refurbishment, and component replacement.
Function:
The box functions as a self-contained protective environment. Key features enabling this function include:
- Heavy-Duty Frame: Supports the substantial weight of the SRB core.
- Sealed Construction: Minimizes exposure to the external environment.
- Lifting and Handling Provisions: Incorporates features for safe movement using cranes and other lifting equipment.
- Internal Support Structure: Provides support and stabilization for the SRB core during transport.
- Access Panels: Allow for inspection and maintenance without removing the core from the box.
- Environmental Monitoring Systems: May include sensors for temperature, humidity, and pressure.
Usage Scenarios:
- Post-Flight Processing: Used immediately after an SRB returns from a space mission for initial inspection and containment.
- Transportation: Facilitates the movement of SRBs between launch sites, processing facilities, and storage locations.
- Long-Term Storage: Provides a secure environment for SRBs awaiting future use.
- Refurbishment and Overhaul: Serves as a platform for detailed inspection, repair, and replacement of components.
- Component Removal: Allows for safe extraction of components for individual testing or replacement.
Common Types/Variations:
While the general function remains consistent, variations exist based on the specific SRB model and operational requirements:
- Solid Rocket Booster Segment Storage Boxes: Designed for the individual cylindrical segments of SRBs.
- Aft Field Joint Storage Boxes: Specifically for the aft end of the SRB, containing critical joint components.
- Transport Containers: Larger boxes designed to hold multiple SRB segments or complete SRBs.
- Mobile Storage Boxes: Boxes mounted on transport vehicles for increased portability.
- Environmental Control Boxes: Featuring advanced environmental monitoring and control systems for long-term storage.
Based on the provided information, the following HS codes may be relevant to “shuttle core storage box”:
- 3923.10.20.00: This HS code falls under Chapter 39: Plastics and articles thereof. Specifically, it covers 39.23: Articles for the conveyance or packing of goods, of plastics; stoppers, lids, caps and other closures, of plastics. 39.23.10: Boxes, cases, crates and similar articles. 39.23.10.20: Specially shaped or fitted for the conveyance or packing of semiconductor wafers, masks or reticles of subheadings 3923.10 or 8486.90. This suggests the box is designed for sensitive electronic components.
- 3923.90.00.80: Also within Chapter 39: Plastics and articles thereof, this HS code covers 39.23: Articles for the conveyance or packing of goods, of plastics. 39.23.90: Other. This is a broader category for plastic packing articles not specifically detailed elsewhere.
- 3926.90.10.00: This HS code is under Chapter 39: Plastics and articles thereof, covering 39.26: Other articles of plastics and articles of other materials of headings 3901 to 3914. 39.26.90: Other. 39.26.90.10: Buckets and pails. While not a direct match, if the storage box has a bucket-like form, this could be applicable.
- 4202.92.04.00: This HS code falls under Chapter 42: Articles of leather or of composition leather, of sheeting of plastics, of textile materials, of vulcanized fiber or of paperboard, or wholly or mainly covered with such materials or with paper. Specifically, it covers 42.02: Trunks, suitcases, vanity cases, attache cases, briefcases, school satchels, spectacle cases, binocular cases, camera cases, musical instrument cases, gun cases, holsters and similar containers; traveling bags, insulated food or beverage bags, toiletry bags, knapsacks and backpacks, handbags, shopping bags, wallets, purses, map cases, cigarette cases, tobacco pouches, tool bags, sports bags, bottle cases, jewelry boxes, powder cases, cutlery cases and similar containers. 42.02.92: Other. 42.02.92.04: With outer surface of sheeting of plastics or of textile materials: Of vegetable fibers and not of pile or tufted construction: Other (871). This applies if the box is made of plastic or textile materials.
Regarding HS code 3923.10.20.00, please note that it specifically applies to boxes designed for semiconductor wafers, masks, or reticles. If the storage box is not intended for these specific components, another HS code may be more appropriate.
