As a final word for wankel engines; their "apex seal" wearing problem is their biggest problem that shortens their maintenance lives. You can also check out Mazda's wankel engines for cars, they keep coming back with improvements but still didn't make a success.
I mean the Liquidpiston company started making this engine long time ago, I have been following ever since they first appeared as I have been looking for engines for my projects.
Baykar's VTOL is a hybrid, so are many others. But their configuration uses two seperate systems actually. Electric part does the vertical take off and landing and fuel engine does the forward propulsion in plane mode. It is not very efficient to keep two different power source and propulsors on...
When will you get the VLS capability in the Navy when we go fully domestic as opposed to a Navantia cooperation. If we can wait then no problem, if we can speed up domestic development again no problem but if we will get that capability 5 years later than when we can actually get it then we may...
Navantia haven't been able to find an export customer for the S80. It has a big overlap of capabilities with our Milden. We want to go fully domestic but the timeframes we are looking at might make a cooperation beneficial. If we can speed up domestic development it would be the best.
For military use, cost is not really an issue, but controllability is paramaunt.
Too bad in Türkiye helicopter sector is too weak. Until TAI started making them with help from the Italians there was no achievement at all. There were tiny remote controlled recreational models. In Japan they use...
When it comes to unmanned system where pilot skill is not required I would say helicopers is the only way to go as they are fully controllable. Gyrocopters shine for safety as they are in autorotation at all times and are much safer than helicopters for this reason alone. Again, kindo, this is...
