    Can thrust vectoring enable use of flaps on pure delta wing?

    Since I asked this question, I have been reading the HBA forum backwards and forwards and found almost all my ideas at least mentioned, while many - discussed in all possible perspectives. Nevertheless, you all, replied to my thread. I appreciate it very much, this is the most welcoming online...

    Can thrust vectoring enable use of flaps on pure delta wing?

    I understand your reasoning, but it sounds kind of dated. There are more than a hundred eVTOL startups https://evtol.news/vectored-thrust, some of them are already delivering and not a single one without computer in the loop.

    Can thrust vectoring enable use of flaps on pure delta wing?

    Batteries are heavy (no ballast required), have much higher density than fuel (less movement), does not change weight being depleted (no trim movement), can be fixed easy and reliably (mechanical pin) and will be moved only twice per flight short after / before landing (can be mechanically mixed...

    Can thrust vectoring enable use of flaps on pure delta wing?

    Thanks, that was one of my questions in the first post. The reason to break a new ground now are new technologies became available. As @Norman mentioned for example power was expensive. But not any more. 1:1 thrust to weight ratio peak is affordable. Electric engines are more flexible as to were...

    Can thrust vectoring enable use of flaps on pure delta wing?

    This is my ultimate goal avoiding all complication with thrust vectoring. It's not about the ailerons being heavy, at low load (pilot only) the nose-heavy state is balanced with ailerons a little up, eating some lift. The cabin inside is 2m deep, you could possibly seat third person in the...

    Can thrust vectoring enable use of flaps on pure delta wing?

    @chris__88, unfortunately I cannot edit anymore the initial post to stack all gathered information in a single place, as here https://aviation.stackexchange.com/questions/71694/can-thrust-vectoring-be-used-to-enable-the-use-of-flaps-on-canardless-tailless-d, but I'll keep updating the reference...

    Can thrust vectoring enable use of flaps on pure delta wing?

    Having battery on-board and given the cost and weight of additional motor - engine redundancy seems to me a must have feature. So, I can optimize the airfoil for cruise only.

    But using them will not get enough lift gain alone nor compensate for nose down pitch.

    Can thrust vectoring enable use of flaps on pure delta wing?

    sorry, fixed the graph. The point is that with more power each pound of thrust is cheaper. My calculation shows, that with just one-third cut of stall speed and Emrax engine the aircraft may become airborne in no time and just 20 meters...

    Can thrust vectoring enable use of flaps on pure delta wing?

    These are the engines I have: https://docs.google.com/spreadsheets/d/1JwkBOlEd-586JH4dOYWpeRn-cwJSJfOzP6lf_C7oIPw Thrust values a measurements for all except EMRAX. Is my estimate for it correct? It seems like even vertical take-off for a single pilot is achievable.

    Can thrust vectoring enable use of flaps on pure delta wing?

    Well, I hope to stay way under the eVTOL budget with home built airplane for two as Marcus Leng did for a while.

    Can thrust vectoring enable use of flaps on pure delta wing?

    No matter how funny it is, it seems that power, thrust and efficiency are things which can make an aircraft aloft faster. With tractor thrust vectoring there seems to be no clear line between V and S, isn't it?

    Can thrust vectoring enable use of flaps on pure delta wing?

    Well, practically speaking, by "delta" I mean roomy cockpit with high EW/MTOW at roadable size. Thanks for idea, will look into it. As @Topaz mentioned, I'm not sure if it can get me close to what rear flaps usually do.

    Can thrust vectoring enable use of flaps on pure delta wing?

    Yes, "Delta" is existing design and is chosen because it checks all the boxes for me. Essentially, I'm fine with some other close designs, like "RMT Bateleur" which is even closer in stall speed but loses in other aspects. It is possible to land it in under 50 meters. That is why I'm looking...

    Can thrust vectoring enable use of flaps on pure delta wing?

    At high AoA there would be no use in flaps, the idea is to land delta "conventionally". Would the drag brake make landing a hard task to nail down or is it just a need for bigger shock absorbers because of high sink rate?
