Lycoming YT-53-L-1
Lycoming YT-53-L-1 is an experimental historical turboshaft variant identified by NASA as the single 825-shp engine installed in the Curtiss-Wright X-100 tilt-propeller VTOL research aircraft. The X-100 used the engine to drive two tilting propellers; this record represents the exact engine variant and does not count the propellers, pivoting nacelles, or Jetivator thrust-vectoring duct as additional engines. The variant is linked to the broader Lycoming-origin T53 family.

- Note
- NASA's paper identifies the Curtiss-Wright X-100 as powered by one Lycoming YT-53-L-1 engine producing 825 shp, driving two 10-foot tilting propellers, and describes the Jetivator exhaust-ducting arrangement.
