MS-357, Lockheed-Martin Aeronautical Patent Collection

Collection Number: MS-357

Title: Lockheed-Martin Aeronautical Patent Collection

Dates: 1844-1988

Creator: Lockheed Martin Corporation

Summary/Abstract: The Lockheed Martin Aeronautical Patent Collection was developed by

the Lockheed Aircraft Company to provide a single source of information concerning aviation-related patents in the United States. The collection spans a period beginning with the initial

experiments with balloons in 1844 to the aviation technologies developed through1988. The

collection is organized according to the United States Patent and Trademark Office 244 Class ofAeronautics and Astronautics. The patents are filed in patent number order according to the sub-

category class number assigned by the Patent Office.

Quantity/Physical Description: 44 Linear Feet (44 Record Center Boxes)

Biographical/Historical Note

The Lockheed Martin Corporation can trace its roots back to the earliest days of modern

aviation. Glenn L. Martin established a company in 1909 that was a major airframe supplier tothe U.S. Military and commercial industries. Around the same time, Allan Loughead founded

the Lockheed Corporation, which also soon became a successful aircraft manufacturer. In 1995,

the two merged to form the Lockheed Martin Corporation. This collection of patents wasoriginally developed and maintained by the Lockheed Martin Corporation.

Scope and Content

The Lockheed Martin Aeronautical Patent Collection documents innovations in aviation from themid-19

thcentury through most of the 20

thcentury. These patents pertain to everything from

dirigibles and gliders to modern day jet engines and in-flight refueling methods. Researchers

who utilize these records can learn much about aviation before the first sustained and controlledheavier-than-air flight and its advancements since. The collection is arranged into series based

on the original classification system for aeronautical patents by the United States Patent and

Trademark Office. Each patent is of the 244 class of aeronautics and astronautics and each seriesis arranged according to the subcategory of this class. Within each subcategory, the files are

arranged according to patent number with the folder indicating the patent number range.

Series I, Miscellaneous, consist of patents pertaining to trailing devices, noise abatement

techniques, lightening arrester and static eliminators, as well as, composite aircraft.

Series II, Aircraft, Heavier-than-Air, contains patents that address weight diminished aircraft,

fluid sustained airplanes and helicopters, and dual propulsion means (horizontal and vertical).

Series III, Aircraft, Lighter-than-Air, houses patents on dirigibles, airships, and hot-air balloons

designs.

Series IV, Aircraft Sustentation, includes patents referring to sustaining airfoils. It also addresses

unique designs for fuselages and struts.

Series V, Aircraft Propulsion and Steering on Land or Water, is the largest series and houses

patents on everything from aircraft control and aircraft power plants, to steerable jets and

floatation devices for planes.

Series VI, Landing Gear, relates to different patents on the design and function of landing gears

for aircraft. Amphibian, retractable, coil spring, fluid pressure, and even inflatable landing gearsare all devised in this series.

Series VII, Retarding and Restraining Devices, contains patents relating to wheel brake

arrangement, water brake arrangement, and aerodynamic retarders.

Series VIII, Landing Field Arrangement, consists of patents on mooring devices and blast

deflectors for aircraft landing fields.

Series IV, Aircraft Structure, includes patents that address fuselage and body designs for cargo

accommodation, seating arrangement for crews, and also shield and other protective devices.Patents relating to aerodynamic resistance reduction as well as airship hull and skin construction

are also found in this series.

Series X, Safety Lowering Devices, consists of patents relating to safely lowering an aircraft to

the ground in the case of an emergency. Parachutes for entire planes and passengercompartments, as well as, safety devices for seats and crew are accommodated in this series.

Some patents on kites are also found in this series.
