3 1 Team Birth on February 2010 by a group of Professors and Students 2 primordial team layout, made by Professors and Students 3 Presentation of the new activity to the whole University Steps creating a FSAE Team 4 First Recruitment and Team Formation 5 search of Sponsors and partners 6 Working on the Car Design
4 For a proper team start: Receiving university support Good visibility in the university Expos and conferences Building a well structured team Drawing up Internal Rules Setting up the foundation for Getting funds Legal recognition Association and Bank Account
5 Frame And Cockpit Aerodynamics The unina corse Team Powertrain is made up of divisions Suspensions Electronic Devices Public Relations and Communication Building and Testing
6 Our internal rules provide that every team member has to be a SAE member. As our team grows and becomes bigger, we plan to found an SAE Chapter in Naples
7 Year 2010 FSAE Concept Car made by the team Unina Corse: UC10
8 First Year of participation No Previous FSAE Projects Boundary conditions No Previous FSAE Knowledge Low Budget
9 We started from here: A blank sheet of paper and a pencil
10 And we Came up with
13 Technical Specifications (1/2): Engine: Honda Hornet 2010, 4 cyl. In Line, 600 cc Supercharged with intercooler Water Cooled Dry sump Lubrification Engine Control Unit: Completely Self-Developed and Built Gearbox: 4 Gear sequential Electro-actuated with pad shifters Frame: Aisi 4130 Steel tubular spaceframe Tig Welded
14 Technical Specifications (2/2): Suspensions: Aisi 4130 Steel Double wishbone triangles Push-Rod Single Damper at the Front with a T antiroll Bar Double Push Rod Damper at the rear with Adjustable Antiroll bar Brakes: 6 piston Brake calipers Brake distributor Aerodynamics: Biplane Front Wing Flat undertray with Diffuser

19 Aerodynamics For the first time in Europe a Formula SAE team has been able to count among its divisions an entire department devoted to the aerodynamics of the vehicle, where the theory of airfoils and the much-studied Bernoulli equation have found an application to develop effective aerodynamic devices.
20 We particularly Focused our attention on the best solution for the Front Biplane Wing and an efficient rear Diffuser
21 Front Wing Design 1. Airfoil selection 2. 2D CFD Airfoil analysis 3. 3D Analysis of the front nose assembly 4. CFD Evaluation of the Overall effect produced on the car by the wing
22 Undertray with diffuser 1. First we estabilished the geometry 2. Then we analized the advantages
23 Frame The first CAD of the frame was made keeping in mind the following guidelines: the drivers Posture Minimum inner space FSAE rule limitations Engine volume
24 Frame Target: Weight < 40Kg. Stiffness > 100,000 Nm/rad Natural frequency > 45Hz. Constraints: Material (AISI 4130) Drivers posture Engine Result: Weight: 32 Kg
25 Natural frequency Since in slalom competitions the Natural Frequency can be 45 Hz, Our frame, in the final configuration, has its first torsional vibration mode at a frequency of about 50Hz.
26 Torsional Stiffness Finite element method and torsional stiffness BEAM 1500 Nm/deg SHELL 1400 Nm/deg SHELL 1852 Nm/deg Optimized Measured at the maximum rotation point SHELL 3268 Nm/deg according to the Car manufacturers method, measuring the stiffness in the area close to the point of application of the force
27 Impact Attenuator Carbon Fiber Reinforced Average Deceleration: 6 G Maximum: 19,3 G
29 Semi-dry Sump To lower the center of gravity To Ensure good lubrification in every dynamic condition Reduce the loss of Engine ventilation Semi-dry Sump A Dual stage scavenger pump The Same pressure pump An External oil reservoir
30 Intake system Naturally Aspirated engine study Supercharged Engine study 1D Model in GT Power and optimization for Intake and Exhaust in Modefrontier 1D Layout in GT Power
31 Exhaust System Silencer, with Helmholtz resonator
32 Engine performances
33 Suspension Division Steps in Designing the suspensions: 1. Calculation of the geometry and kinematics, keeping control of the variations of the charateristic angles 2. Sizing and CAD of the elements 3. Finite Elements Analisys
34 Front Suspension
35 ROLL BUMP
36 Rear Suspension

38 Communication The design work is being continuously helped and supported. our passion is shared outside the team. Spreading our work to others means giving the students and motosport fans the possibility to experience the world of car racing, organizing events, seminars, and using the powerful internet possibilities.
39 Communication What s a race car? How is it made? What are its secrets? UniNa Corse is not only a lab project, but a meeting point between studies, ambitions and passions: all these sparks ignite enthusiasm!
40 Website Facebook Communication The continuous presence of the Team in popular media channels Forum Media maintains a relationship in vivid colors for those who believe in our project on the outside. Frequent updates, the visibility offered to partner companies and external collaboration, have increased everyone s interest and the participation of all.
