Background information

Aircraft morphing, i.e. seamless controlled shape adaptation of the wing geometry hasattracted the research community and industry for more than 30 years because of theinvolved challenging questions in fundamental engineering sciences, the potentialimpact on aircraft emissions and noise and last but not least the possibility to tailoraerodynamics to a large set of different flying conditions.CMASLab has intensively researched for the past 15 years on innovative morphingapproaches, covering structural design, system integration, aerodynamics, actuation,control as well as material and fabrication aspects.

Overall objectives & contents

The proposed project is aiming at demonstrating the possibility to fully control the flightof tailless aircraft (e.g. flying wing) just by selective deformation of the main structure,i.e. without the utilization of movable surfaces. The design approach is considering theintegration of compliant elements into novel lightweight bionic design solutions.

The project will be highly interdisciplinary and include conceptual, embodimentdesign, analysis and simulation, fabrication of components and prototypes, systemintegration, wind tunnel and flying tests. Involved disciplines include lightweightdesign, mechanics, fluid dynamics, control and manufacturing.

Deliverables

We pursue the ambitious target to realize a flying demonstrator with a wingspan ofapprox. 3 m, and a cruise speed up to 40 m/s. The main structures will be made ofCarbon Fibre Reinforced Composites (CFRP) and fabricated at CMASLab takingadvantage of advanced prototyping techniques (3D-printing).

Tasks & timeline

Conceptual phase (Sept-Oct)The initial design study combines design, numerical studies and prototyping withsmall iterations in rapid succession. The realization of flying demonstrators ofincreasing complexity using rapid prototyping and the frequent testing of designiterations will allow for an efficient design phase, reducing the overall risks.

Design phase (Nov-Dec)This phase will be characterized by the realization of the detailed construction,including a thorough numerical evaluation of flight dynamics and aeroelastics, with aspecial focus on aerodynamic peculiarities due to morphing. Selective flight test willcontinue.Production phase (Feb-Mar)Once the design is frozen and the numerical evaluations yield satisfactory results,production and assembly of several flight test models follows. Building a small seriesof prototypes allows for backup in case of any flight test mishaps and for small designadjustments as the need may arise in the flight tests.Flight test phase (Apr-May)A series of standard flight test maneuvers will be flown in order to thoroughly evaluatethe developed concepts, in particular with regard to controllability and maneuverabilitywhere morphing may pose particular challenges.

Organisation

Budget (estimation)The overall project costs are estimated around 60-80 kCHF. A large part of thisbudget should be covered by in kind sponsoring. CMASLab will anyway provide seedmoney, financial backstop and access to potential sponsors.Support from CMASLab

CMASLab has a record of successful focus projects,including CIEO, Carbon Factory, 3D Carb, ftero1,ftero2, ftero3 and Motostudent, and boasts anoutstanding industry network.

Facilities & infrastructure include among others stateof the art simulation capabilities, and well equippedlaboratories for the fabrication and characterizationof composite materials and adaptive structures.

This ambitious focus project aims to develop a first proof-of-concept of a functional quadruped with the form of a lifelike animal robot.

Unlike most existing quadrupeds, this robot design will be based on an animated character created by an artist, which holds as a basis to optimize the kinematics and dynamics.The project will build on RSL expertise within quadruped robot and actuator design and control, and will be co-advised by Disney Research and RSL. The artistic input will be provided by Disney Research.

Goal: build a prototype of an electric race car according to SAE rules (Formula Student Electric).

Team: 12 bachelor students start in the focus project to design a new car.

Projects: The car is designed and built in different modules: chassis, suspension, aerodynamics, batteries, drivetrain, motor controller, electronics and controls

Cooperation: HSLU (Lucerne university of applied science) offers to work on the car as “bachelor project”. Three to four students each year join the team in the electronics module.

Projects are organized under Prof. Dirk Mohr, supervisor: Jörg Heingärtner

Swissloop is a student-led association, founded bystudents from ETH Zurich in 2016. The main goal ofSwissloop consists in researching and advancingHyperloop transportation while developing a state-of-the-art pod prototype over the course of one year. Teammembers are actively contributing to all technical andoperational aspects from the first concept to a finalHyperloop pod and final event in Switzerland as well aspartaking in international events.

Swissloop participated for three consecutive years inElon Musk’s Hyperloop Pod Competition in Los Angeleswhich resulted in a second and a third place worldwideas well as an Innovation Award.

Swissloop

Initial ideas for using vacuum tubes to reduce airresistance date back to the 19th century. However, it wasnot until the publication of Elon Musk’s white paper“Hyperloop Alpha” in 2013 that this idea gained traction.The Hyperloop concept combines the speed of aircraftwith the high frequency of trains. It creates a completelynew and efficient way of traveling, which allowsenvironmentally friendly locomotion due to lower energyconsumption in a vacuum.

Hyperloop Concept

Main objective for next year’s season is to take the nextbig step in Hyperloop Pod development, namelyimplementing a levitating Linear Induction Motor anddesigning a corresponding pod around it. This includesunderstanding how the motor works and can achievelevitation, but that is only the beginning. With high targetvelocities, the structure of the pod needs to withstandhigh forces. As the motor is not inherently stable whilelevitating, the pod needs additional stabilizationmethods, with a focus put on contactless forms ofstabilization. Application of gained knowledge so far inMechanical or Electrical Bachelor’s and as beyond willbe guaranteed.

We are looking for 8 motivated Bachelor Studentscurrently in their 4th Semester from MAVT and ITET.Together with Master Students and Team Leads theywill form a strong team of roughly 20 people in total.
