From L+K 1968/2,

you feel this model had a mid-wing (not low-wing) ?.

 

[richard B]

It is just like in Post #42 : low-mid-low wing ...

Enjoy the Day! Mark

Why they choose T-tail for trainer? It is dangerous while deep stall.

What ?,It's not a problem.

Because

Why they choose T-tail for trainer? It is dangerous while deep stall.

What ?,It's nor a problem.

I have read this:
The flow condition of deep stall is a common problem of T-tail aircraft at high angles of attack. When the aircraft reaches a certain angle of attack (deep stall angle of attack) after the wing stall, the efficiency of the elevator will be reduced due to the wake of the wing, which makes it very difficult to change the deep stall state.

So I think that the T-tail is not good idea for a trainer.

More on the Dornier P.375 from Dornier Post 1/2 1969 in-house magazine attached as a PDF.

Here a German article about the Dornier P.375.

Deutsches Kampftrainer-Projekt mit Weitblick: Dornier plante Jet P.375 als Multi-Talent

In den 60er Jahren erdachte Dornier eine Strahltrainer-Familie, die sogar Überschall- und Senkrechtstart-Versionen beinhalten sollte.

Edit:
I added three pictures from this article to this post today, to show the difference between the versions, either with a sub- or a supersonic wing.

Interestingly, Hawker Siddeley Kingston came up with an almost identical design study for the P.1182.

…and Potez for their Potez 92:

Must have been a case of cross-pollination across the Channel.

 

[Hood]

The Potez P.92 design pre-dates the others, dating from 1964. The HS.1182 study and P.375 were both 1969 designs.
