Garrett AiResearch

Garrett AiResearch was a Torrance, California-based manufacturer of aerospace components, including turboprop engines, turbochargers, avionics, hydraulics, and cabin pressurization systems for aircraft and spacecraft. Operating across multiple facilities in California and Arizona, the company scaled to employ over 6,000 people and eventually generated approximately $2 billion in annual sales as a corporate subsidiary. The manufacturer supplied critical aviation and automotive systems to major commercial and industrial clients, including prominent customers such as Boeing, Douglas, Lockheed, Audi, and Caterpillar. By 1982, the manufacturing unit managed around $200 million in purchasing commitments, though its operations later faced Pentagon scrutiny over procurement deficiencies. The enterprise underwent significant corporate restructuring, merging with Signal Oil & Gas in 1964 before ultimately becoming part of AlliedSignal. The industrial organization was originally founded in Los Angeles in 1936 by John Clifford Garrett.

High-Level Overview

Garrett AiResearch was a pioneering aerospace manufacturer specializing in turbochargers, turboprop engines, cabin air compressors, and auxiliary power units (APUs) for aircraft and industrial applications.[1][2][3][4] It served commercial aviation, military, and industrial sectors by solving critical challenges in pressurized flight, engine starting, environmental controls, and forced induction systems, becoming a leader in high-barrier-entry, technology-driven products like gas turbines and turbochargers.[2][4] The company demonstrated strong growth momentum post-WWII, expanding from aircraft tools to global production, including 20,000 turbocharged engines in U.S. municipalities by 1952 and major contracts like 5,000 turbochargers for Caterpillar in 1955.[1][4]

Origin Story

John Clifford "Cliff" Garrett founded the Aircraft Tool and Supply Company in a one-room office in Los Angeles in 1936, evolving it into the Garrett Corporation by 1938-1939 with divisions including the AiResearch Manufacturing Division.[1][3][4][6] In 1939, Garrett established a small research lab focused on "air research" for pressurized passenger aircraft, developing cabin air compressors as a flagship product.[1] Post-WWII, AiResearch recruited German expert Prof. Werner von der Nüll as Head of Research, accelerating advancements in turbomachinery; by 1945-1952, it produced the first successful gas turbine and shifted facilities to Phoenix.[2][4] Early traction came from WWII turbochargers and avionics, with the 1954 AiResearch Industrial Division (AID) marking a pivot to diesel turbochargers.[4]

Core Differentiators

• Technology Leadership and Systems Integration: Garrett AiResearch excelled in turbomachinery, control systems, materials under extreme conditions, actuation, and valves, building complete systems rather than components (e.g., valves plus controls).[2]
• High-Barrier Business Model: Targeted businesses with high entry costs, prioritizing best-in-class quality over lowest price, supported by powerful sales, government relations for prime contracts (Army, Navy, Air Force, NASA), and field engineers embedded with customers.[2]
• Product Innovation: Pioneered cabin air compressors, first gas turbine APUs for aircraft (providing engine starting, pneumatics, hydraulics, backup power), and turbochargers for aviation, mining, locomotives, and tractors.[1][2][3][4]
• Manufacturing Scale: Operated key sites in Torrance, CA, Phoenix, AZ, and Skelmersdale, UK, with rapid scaling like the 1955 Caterpillar order.[1][2][4]

Role in the Broader Tech Landscape

Garrett AiResearch rode the post-WWII aviation boom and jet age trends, capitalizing on demand for pressurized cabins, reliable APUs, and turbocharged engines amid military contracts and commercial air travel growth.[1][2][4] Timing was ideal: WWII turbocharger production built expertise, while 1950s municipal and industrial adoption (e.g., sewage systems, Caterpillar tractors) expanded beyond aviation.[4] Market forces like high R&D barriers and government priming favored its tech-driven approach, influencing the ecosystem through tech transfers (e.g., German expertise) and innovations like the first passenger aircraft gas turbine APUs, which set standards for environmental controls and propulsion.[2][3] Its dragster experiments in the 1960s highlighted experimental compressed-air tech, though short-lived.[5]

Quick Take & Future Outlook

Garrett AiResearch's legacy endures through spin-offs like Garrett Motion (turbochargers) and Honeywell integrations, having merged into Signal Companies (1964), AlliedSignal, and beyond.[3][4][5] What's next traces to its DNA in modern turbo tech for vehicles and aviation, shaped by electrification, sustainable propulsion, and hypersonic demands. Its influence evolves via Garrett Motion's ongoing production, underscoring how early aerospace bets on high-tech barriers continue powering global mobility—from 1939 labs to today's forced induction dominance.[4][6] This trailblazing path from Cliff Garrett's one-room start defines enduring innovation in compressed air and turbines.
