RENO CONVENTION 2012Innovation in thetwo-seater classArcus Developement

Preliminiary considerations : Swen Lehner Christoph Wannenmacher Joachim Krauter

Preliminiary considerations: Dr. Werner Würz Director of the laminar wind tunnel of the University Stuttgart

Preliminiary considerations Reference was Ventus 2cxM/Nimbus 4DM: Comparable stall speed Comparable take of speed First start-airfoil: WW99k137 Wing area: 15,6 m2

Arcus - Design: Aerodynamic Aeroelastic Flight characteristics Project: Arcus Structure Airworthiness requirements Operation limits

Arcus – Design: Airfoil optimizing: Werner Würz, LWK Stuttgart Wing geometry - optimizing: Jan Himisch Karl Heinz Horstmann DLR Braunschweig

Arcus - Design: Winglet optimizing: Prof. Mark Maughmer, PSU

Arcus - Design: Aeroelastic optimizing: Andreas Lutz (Aka München, now Schempp-Hirth) Jan Schwochow DLR Göttingen

Arcus – Molding:

First mold Beginning January 2009

Resumee (subjektive CG)• Agil, good manoevrability• Arcus with high wingloading climbs as good as the Duo´s•Advantage by straight flights with high speeds• Starting, landing: Flaps, 3-panel airbreaks, high and springloaded undercarriage, roomy cockpit, comfortable• Performance – for example Reinhard Schramme inBitterwasser/Namibia• makes fun

Quintus Innovation in the Open ClassDevelopement

Preliminiary considerations : -Pilot desire for a fast Open Class selfaunch sailplane -With a high wingload range for competition pilots -AND easy ground handling and agil in the air for record flights, for recreation and expedition and above all: for fun flights New concept necessary!

Preliminiary considerations : Span + wingarea downsizing, high aspect ratio Low weight for wingloads below 39kg/qm (6,9 lb/ft2), With water ballast extrem high wingloading 58kg/qm (almost 12 lb/ft2) ! Solution: new wing design with 23m (75,5 ft) as a result of fruity cooperation with Lange Aviation

Preliminiary considerations : Fuselage - Comfort - Safety (new strict CS 22) - Elegance Wing - Modern airfoil - High performance with high wingloads . and in high speeds

Preliminiary considerations : Propulsion System -New Solo 2625-2i with electronic controlled fuel injection for max. power also at high density altitude -70 HP -New, fully automatic ILEC control for easy operation („ON-OFF switch“) -Integrated steering tailwheel /(System Lange)

First Design Study :

„Sister Ship Antares 23E : Modern airfoils from Loek Boermans for Antares and Quintus

Preliminiary considerations :Winglet optimizing: Prof. Mark Maughmer, PSU
