eDBF V2 - Research Design (IVTOL uTVC)

Updated: Model Scaled Down Further (2nd Oct)

(If you have problems viewing the pictures, please wait for the pictures to upload properly)

Theme
The theme is to design and implement Vertical Take-Off & Landing on a conventional airborne design using Thrust Vector Control

Plan
Since i am an aviation engineer, i feel i can work without a ready-made plan. i plan to do something that will be self-made or maybe take inspiration from fiction work (like star trek etc)

A nice and very abitious theme, i'm listening

that is soo good i like is very much because i like Vertical Take-Off plan best of luck

wating for ur project

Sayem

You have taken on a tough project. I had recently assisted an Emirates Aviation College student in Dubai on a similar project but which was not successful as:

- lateral roll control was not possible
- Even with a contra-rotating gimballed power system, the thrust was inadequate for vertical take-off

The forward flight was good and so were the high alpha landings at very slow forward speeds. In retrospect I think that instead of the central prop system it would have been better to use two gimballed large diameter low KV props in each wing to attain better roll control.

Have a look at this link.

But you being an Aviation Engineer may Inshallah succeed where we couldn't.

@skysailor

i respect you for your concern

yes you are right, lateral roll control is not possible

and about the thrust issue, i believe that it is all about using correct kv's

lets hope for the best and see to what extent can progress be achieved!

and abt your comment on being an engineer. from my past experience, i have come to know that aerospace hobbyists have more practical knowledge than engineering students because of their exposure to flight whereas a student is more towards theory. hope u agree on it.

and i am as inexperienced as any intermediate level hobbyist is! i am still a learner and will always be...
