The main load bearing landing gear is in a bicycle setup, with 2 outriggers for stability. This allows the gear to be lighter, stay close to the center and out of the way for the jet blast. The Lockheed U-2 also has its gear in the bicycle configuration and takes off and taxies with detachable "pogo" outriggers for stability.

The Harrier is designed around its rather large centerline engine with its 4 non-standard exhaust ports. In order to balance properly, the engine's nozzles have to be in just the right place and we can't have annoyances like landing gear doors opening just before landing and deflecting the thrust stream that is keeping the thing in the air. Fighter jet ...

How does the Harrier avoid engine damage from dirt ingestion during rough-field operations? The short answer is that they don't. They avoid using these FOD-laden strips if possible, but doesn't have any kind of active method for reducing FOD damage from debris ingestion. This is supported by an RFP that NAVAIR put out asking for proposals to reduce FOD for ...

Because when selecting aircraft the requirements were for close air-support and to be able to operate from amphibious assault ships like the USS Tarawa and the USS Nassua. These ships have very small decks that aren't geared towards launching larger aircraft like the F-18.

the F35 has a ton of electronics that the Harrier could only dream about, but I will focus on propulsion differences. The biggest is that the F35B uses a separate lift fan in front of the engine, oriented to provide vertical lift that balances the vectored thrust from the rear of the engine. The lift fan is disconnected when flight speed is obtained and ...

And if the Harrier had been a conventional terrestrial fighter, it probably would have used a ubiquitous tricycle landing gear. The driver for Harrier's unusual landing gear configuration is the requirement to hover via an unconventional single engine vs available fuselage space. This necessitated that the Rolls Royce Pegasus engine to be located directly ...

In the Harrier, the bypass air from the large diameter low pressure compressor of the Pegasus engine is ducted through the front pair of nozzles while the remaining gas output from the engine passes through the rear pair. Rolls Royce designed the Pegasus engine with the main rotating components, the low and high pressure compressors and the corresponding ...

The F-35B can automatically do a VTOL landing while the Harrier is manual. Also the F-35B has a more powerful engine that has an air opening on the top of the jet to increase air intake for VTOL operations. The performance difference is that the F-35B can go faster than the speed of sound while the Harrier cannot. Not to mention the F-35B has all the ...
