Abstract VTOL (Vertical Take Off/ Landing)
Aircraft designed on X-Plane®
By: Zak Sky Davalos King
The Need for a Jet VTOL
• Response time of a jet
• Versatility of a helicopter
• High operational flight ceiling
Existing VTOL Designs• V-22 osprey• F-35 JSF• Dornier Do.31
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
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
Designing the Basics
• Began with the fuselage(main body) and Nacelles
Designing continued
• Wings• Misc. bodies• Landing gear
Programming the Specifications
• All the set data like engine specs and weight had to be programmed in
• Not necessarily realistic, just figures decided upon
Key designs
AVX2B Cardinal AVX3B L.E.A.W.
AVX4 Tall Tail AVX6 T.W.L.E.
The Results
• Only one true success• Several designs were capable of vertical flight• Only one able to transition to horizontal flight
AVX 6 T.W.L.E.AVX 3B A.F.T.T.E.S.
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
Evolution
• Fuselage changed on occasion
• Wings and engine nacelles changed the most in attempt to change balance or improve aerodynamics
The “What Went Wrong” factor
• Problems were numerous
• Fixes often resulted in a new model
• Fixes often resulted in a new problem
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
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
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
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
