GE Aviation J31 / I-16 Turbojet Engine Manuals Collection
This comprehensive technical archive contains essential documentation for the General Electric J31 (military designation I-16) turbojet engine—one of America's pioneering jet engines that powered the first generation of U.S. military jet trainers and experimental aircraft during the critical transition from propeller to jet propulsion in the late 1940s and early 1950s.

- Parts Catalogs – Illustrated breakdowns with part numbers and specifications
- Technical Orders – Official military technical documentation and service bulletins
- Operating Instructions – Engine operation, limitations, and performance data
- Troubleshooting Guides – Diagnostic procedures and corrective actions
Historical Context:
The General Electric J31 (I-16) was developed in the immediate post-WWII period as GE transitioned from its wartime centrifugal-flow turbojet designs to more efficient axial-flow configurations. Based on GE's experience with the I-40 (J33) engine, the J31 was a smaller, simplified turbojet specifically designed for trainer aircraft and light jet applications.
Producing approximately 1,000 pounds of thrust, the J31 featured a single-stage centrifugal compressor and single-stage turbine in a compact, reliable package. This made it ideal for training the first generation of U.S. Air Force and Navy jet pilots who would go on to fly the F-86 Sabre, F-84 Thunderjet, and other frontline jets of the Korean War era.
Notable aircraft powered by the GE J31/I-16:
- Lockheed T-33 Shooting Star (early variants) – America's primary jet trainer
- Cessna T-37 Tweet (prototype) – Side-by-side jet trainer development
- Ryan FR Fireball – Experimental composite-power fighter
- Various experimental aircraft – Research platforms for early jet technology
The J31 represented a crucial stepping stone in American jet engine development. While it was eventually superseded by more powerful engines like the Continental J69 (license-built Turbomeca Marboré), the J31 served its purpose admirably during the critical years when the U.S. military was building its jet training infrastructure and developing operational doctrine for jet-powered combat aircraft.
GE's experience with the J31 contributed directly to the company's later success with the J47, J79, and subsequent generations of military jet engines that would power American air superiority for decades.
