Abstract VTOL (Vertical Take Off/ Landing) Aircraft designed on X-Plane®
By: Zak Sky Davalos King

2. The Need for a Jet VTOL Response time of a jet
Versatility of a helicopter
High operational flight ceiling

3. Existing VTOL Designs
V-22 osprey
F-35 JSF
Dornier Do.31

4. Design Criteria for my VTOL
Flight ceiling of 30,000 ft
Jet turbine engine(s)
VTOL capabilities
Payload capacity of at least eight people
Light weight, under 40,000 lbs

5. X-Plane® Software I used to design planes
Developed by Laminar research
Utilizes several programs to design and a simulation program to test
Allowed me to work on project easily and cheaply

6. Designing the Basics
Began with the fuselage(main body) and Nacelles

7. Designing continued
Wings
Misc. bodies
Landing gear

8. Programming the Specifications
All the set data like engine specs and weight had to be programmed in
Not necessarily realistic, just figures decided upon

9. Key designs
AVX2B Cardinal
AVX3B L.E.A.W.
AVX4 Tall Tail
AVX6 T.W.L.E.

10. The Results Only one true success
Several designs were capable of vertical flight
Only one able to transition to horizontal flight
AVX 3B A.F.T.T.E.S.
AVX 6 T.W.L.E.

11. The Prize of the Project
One true success, AVX 3B M.N.T.E.S
Forward nozzles given lateral and vertical cants to add stability to flight during transition

12. Evolution Fuselage changed on occasion
Wings and engine nacelles changed the most in attempt to change balance or improve aerodynamics

13. The “What Went Wrong” factor
Problems were numerous
Fixes often resulted in a new model
Fixes often resulted in a new problem

14. It Works, but it Doesn’t
The designs may work in the program, but in actuality may not be feasible
Certain things are not applied in the software, such as material integrity and individual part weight

15. How they fly 6 designs capable of vertical flight
10 can only fly conventionally
7 cannot achieve flight at this time
1 capable of complete vertical flight and transition

16. Continuation and Completion
Project is not finished, efficiency can be improved, and realism improved
Time is the only needed factor at the moment
Real models would be necessary for to validate results
More expertise would help trial and error

17. Thank you Mr. McGinnis for introducing X-Plane and expertise
Mr. Spangler for guidance on process and finding contacts, as well as founding the class
Dennis for thoughtful questions and ideas
Friends and Family for supportive attitude and asking good questions
