TRANSPORTING

|  | B64 |
AIRCRAFT; AVIATION; COSMONAUTICS

|  | B64G |
COSMONAUTICS; VEHICLES OR EQUIPMENT THEREFOR (apparatus for, or methods of, winning materials from extraterrestrial sources Fulltext... Hierarchy... Expanded...E21C 51/00)

|  | B64G |
Note(s) The term "cosmonautics" in this sub-class, includes all transport outside the earth's atmosphere, and thus includes artificial earth satellites, and interplanetary and interstellar travel. This sub-class deals only with vehicles, equipment, etc., which are peculiarly adapted for cosmonautics. Thus, vehicles and equipment applicable to both cosmonautics and aeronautics are classified in the appropriate aeronautical sub-class of class Fulltext... Hierarchy... Expanded...B64.

|  | B64G 1/00 |
Cosmonautic vehicles; Propelling or controlling thereof; Equipment for use therein; Equipment for crews thereof (cosmonautical measuring instruments, see the relevant classes; protective clothing Fulltext... Hierarchy... Expanded...A62D)

|  | B64G 1/10 |
· | Artificial satellites; Systems of such satellites (radio transmission relay systems Fulltext... Hierarchy... Expanded...H04B)

|  | B64G 1/20 |
· | Self-propelled vehicles; Propelling, steering or controlling vehicles (producing a reactive propulsive thrust Fulltext... Hierarchy... Expanded...F02K, Fulltext... Hierarchy... Expanded...F03H)

|  | B64G 1/30 |
· | Protecting against or using radiation (Fulltext... Hierarchy... Expanded...B64G 1/20 takes precedence)

|  | B64G 3/00 |
Observing or tracking cosmonautic vehicles (radio or analogous wave systems for navigating or tracking Fulltext... Hierarchy... Expanded...G01S)

|  | B64G 5/00 |
Ground equipment for vehicles, e.g. starting towers, fuelling arrangements (Fulltext... Hierarchy... Expanded...B64G 3/00 takes precedence)

|  | B64G 7/00 |
Simulating cosmonautic conditions, e.g. for conditioning or training crews

|  | B64G 9/00 |
Cosmonautics not otherwise provided for
