How Jump Jets Hover: Harrier Nozzles vs the F-35B LiftFan

A comparison of vertical takeoff concepts highlights two distinct approaches to hover capability. The Harrier relies on swiveling four Pegasus nozzles and uses puffer jets to control vertical movement.

In contrast, the F-35B achieves its hover capability with a LiftFan system located behind the cockpit, described as providing 29,000 horsepower of lift propulsion.

The briefing summarizes how these two jet designs manage vertical thrust and control during hover, illustrating the divergent engineering paths within jump jet technology.

No specific incidents, dates, or operational outcomes are provided in the material, and no aircraft details beyond the described propulsion concepts are stated.
