- Marduck 9y agoMissing tail-sitting rotor wing aircraft: very few components that aren't used in both modes of flight.

- thearn4 9y agoIt's an interesting alternative to visualization of tree-based hierarchies
- mrfusion 9y agoShouldn't the falcon 9 be included?
- TrainedMonkey 9y agoWhile F9 is really awesome, it is not an aircraft ^^
- mrfusion 9y agoHow about a gyrocopter or is that not a short takeoff?
- pdelbarba 9y agoMost are not especially short takeoff but many can pretty much land vertically
- mrfusion 9y agoMany of these become very viable with the advent of electric aircraft. Tailsitters being the simplest.
- TheSpiceIsLife 9y agoWhy would electric power make any of these more viable? All the battery technology we presently have has worse energy density than av gas or jet fuel.
- ge96 9y agoYeah nice thing about gas gets lighter doesn't get weaker unlike batteries, gets weaker, stays the same weight. Guess it depends how far down you run the batteries.
- mrfusion 9y agoThe main thing is a small electric motor can provide a lot of power. It's difficult to provision a gas powered aircraft with an engine powerful enough for vtol but it's not a big deal for an electric.
- TheSpiceIsLife 9y agoAren't all commercially available, and military grade, VTOL aircraft either liquid hydrocarbon powered or rockets? I'm not aware of any electric powered aircraft in the same markets.
- Gravityloss 9y agoA tailsitter has the drawback of being susceptible to winds when landing.
- pdelbarba 9y agoAm I the only one who thinks the X-32 got shafted in the JSF project? It's a pretty good example of keeping a design simple.
- NegativeLatency 9y agoNo, I thought it was a good looking plane. Too bad they changed up the requirements so late in the selection process.
- mrfusion 9y agoSometimes looks do matter :-(. https://m.imgur.com/eb1ltEK https://m.imgur.com/eb1ltEK
- ge96 9y agoDo cyclorotors count or no Also the jet engine stand that they tilt forward and they cruise around on single man. It looks like a flying podium haha. What about jet-tip helicopters or fall under helicopters too yeah
- ge96 9y agoOh man so cool, there are great footages on YoyTube under Nasa Dryden I think. Like old research videos on flat spins, aeroelasticity, one these was in there the Vertol 76 that's a cool video that bubble canopy and those twin rotors.
- whyage 9y agoThis seems to be old; the X-35B is now F-35B: https://www.f35.com/about/variants/f35b https://www.f35.com/about/variants/f35b
- Sephr 9y agoMissing the Lilium Jet and the XTI TriFan 600.
- blorsh 9y agoThey left out the recent DARPA idea of helicopter-style blades that retract into a disk-like wing. They left out designs that transition rapidly and automatically, without sustained hover. For example, an aircraft with a pair of thrust-vectoring engines could be equipped with a nose gear that tosses the front upward, allowing an automated takeoff. (too fast to be done manually) Landing could be similar, with a long and heavy-duty node gear that can take a bit of shock. Another approach is a solid-fuel rocket, again just enough to support the nose.
