Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

B64G 100

US Classification:

244158R, 244190, 244172, 244 63

Abstract:

A reusable first stage ( ) includes a booster engine system ( ) for providing thrust during launch, a structural assembly ( ), canards ( ), jet engines ( ), wings ( ), elevons ( ) and retractable landing gear ( ). After separation, the jet engines ( ) and aerodynamic control surfaces are used to return the first stage to a landing strip. The booster system ( ) includes a structurally stable outer skin system such as an isogrid structure. The first stage ( ) is thereby adapted for controlled descent and recovery with minimal structural enhancement or added mass.

International Classification:

C09D 510

US Classification:

106 1421

Assignee:

PQ Corporation - Valley Forge PA

International Classification:

E02D 1506

US Classification:

405222

Abstract:

A method of formless underwater casting of cement is disclosed. The method involves the addition of silicate to water in which a structure bound with Portland cement or high-alumina cement is to be cast. The cementitious mixture as a slurry is then poured into the water to form a structure. The silicate and cementitious mixture can be placed in the water at the same time using concentric nozzle systems.
