HUMAN POWERED FLIGHT!! Niall Patterson flies Lazarus MK2 - 31st of June 2021 - Icarus cup flight

[@Jonrobrt]

Really great to see more interest in human-powered flight!

[@nickrich56]

Not bad, maybe try it on a slope like hang gliders do. Once you've managed to get airborne your design kicks in just like the pilot.😊

Am I the only one who notices this one guy who nearly runs into the blade... 0:24

[@raknoknak]

yes

[@yaseen157]

Unfortunately, that was me! Yes it is bad practice, yes I don't recommend doing what I did, and yes I won't do it again. In the moment I assure you I was watching the propeller (it looks worse from this angle because you can't see how far to the side I was. Safety comes first and I have learned :)

[@SunilSundar]

Why aren't HPAs biplanes? Wouldn't it make for a shorter wingspan and a lighter stiffer structure?

[@SUHPA]

While it's possible to arrange the wings in biplane form to reduce span for the same lift, the mutual interference between each wing plane causes additional "interference" drag. Sure it *could* result in a lighter structure, but the drag penalty makes it much harder for a pilot to sustain the required power (humans find it exponentially harder to maintain a given level of cycling power output). The trade-off for weight saving isn't worth it!

[@SunilSundar]

@@SUHPA Thank you. Can I see your structural calculations for the Lazarus MkII. thanks

[@bryanlallen]

You’re describing the MIT Chrysalis. Well, and the MIT BURD, but that one was trash. Look up Chrysalis.

Pretty Shure his name is Tombo. He destroyed the first prototype going down a road

[@jmag579]

Well….. he flew

[@MR-backup]

LOL

[@peterross97]

Ironic that the solution to their problem rides in at the last second. Make your platform a recumbent, and so many problems vanish.

[@aayush_789]

this is fine, but too much flex in elevators

[@mikedee8876]

V1......wheels up!.....stall ....stall....stall....crash at 8 mph....nice try

[@wickedleeloopy2115]

Tour de crash 😆

[@lambdaprog]

Too heavy.

[@Manigo1743]

Lol.
