Abstract:
The removal of tetraethyl lead (TEL) from U.S. automotive gasoline has caused concern within the general aviatin (GA) community because of possible legislated environmental of supply restrictions on TEL, an essential ingredient in existing high octane aviation gasolines (avgas). At the same time, the GA industry which was besieged by numerous product liability suits in the past has seen a resurgence since the passage of the GA Revitalization Act in 1994. Because aircraft typically remain in service for many years, the survival of the industry may well depend on the availability of a high octane unleaded gasoline that provides a safe level of power and antiknock performance to the existing fleet. This paper describes the tools and techniques used by one team to develop fuel that provide the required antiknock quality while meeting most of the other criteria of the existing specification for high octane avgas: ASTM D 910 Standard Specification for Aviation Gasolines.
