Good Night
I'm a newbie -more than 5 years of experience- Aeronautic Engineer and Aeronautical Technician (with all the hours of Theoretical Instruction but without license because in Colombia Ultralights doesn't count :mad2::mad2, I participated in all the certification program of the Criquet Fi-156 Storch (75% replica) making some manuals (AMM, KAI, IPC, ......), also I built the LSA Condor and one teenie two, with some experience with composites.
Now i'm designing with the intention of construction the EFA-100 Tigrillo (Eduardo Fadul Aguirre - 100 :gig
The conceptual design is done and structural 30%.
Working currently on the manuals too, and I want to really understand the CG envelope, I have all the cg ranges (empty, zero fuel, take-off) but i dont know what is the range at the WTO
(Airframe Stress Analysis and sizing - Niu - Page 34)
At WTO my cg position is 0.18 %MAC, so why there is a range????
Also I want to ask if there is a book with the new airfoils (I had Theory of wing section, but i want the nasa-GW and all the new), and what is the protocol to design the winglets
Thanks for all
