TRL 2 starts in 2013. It is planned to have a 2 years duration.
Projet and tasks are made according to Lesser Open Bee License 1.3
Bee-Plane TRL 1 Year 2012 : First aeronautical configuration to be studied in details is the one resulting from TRL1.
TRL2 Project Overview
Project description at beginning of TRL2 :
Additional documentation and numerical mock-up
All technical work done according to the open source paragraph of the Lesser Open Bee License 1-3 is available within a dedicated IT server. Access is provide on request.
Guidelines
Basket
Basket is design to be optimum for passengers frequent flight, then it is adapted to other usage (fret, hospitals...)
Basket with three pressure bubbles, Internal structure adapted to 3-4-3 seats configuration
Central luguage area for passenger basket (200 PAX in 2 classes), Only 1 central large main door on each side.
Basket with APU, 4 electric wheels, fuel tanks between bubble spaces
Bee
Flat surface bellow bee with ISO standard dimensions (width 2,44m)
1 pilot behind each other, or only 1, or even none.
Access between basket/bee is planned to be just before front attach system of the main wing.
2 turbopropeller TP400 on main wings, 1 central turbofan (SAM 146) on the back, or even 2 on the back for military usage(Silvercrest * 2)
Variable inlet casing for rear turbofan, behind cockpit and wings, diameter of the turbofan = 1m.
Landing Gears and wings
Bi-taildragger configuration, with lower rear wings that finish with vertical ends for each wheels.
Landing gear with external rotation. Wheels goes behind Turboprop engines
Upper rear wings that goes out at 45°, from the attach system point.
Studies
Studies will includes :
- Configuration definition
- Aerodynamic
- Accoustic
- Mechanical
Projects already finished:
EM Normandy : Partnership strategy
SupMeca : Airport Studies
SupMeca : overall design studies and Collaborative projet
SupMeca : landing gear definition
Projects near completion :
None : "summer time"
Projects planned for september 2013 :
Ecole Centrale Paris : Continue AAS Analysis for Aircraft Sizing tool, and implement lateral flight stability calculation.
Estaca : Cabin Layout, Structural studies, Inboard Energies, certification
INSA Rouen : Continue Engines parametric model (and apply to different future aircraft configuration, including BeePlane)
IPSA : wings studies
Trinity College : Accoustic
Potential projects within universities and engineering schools
EPFL : Impact on transport system
