Vir­tu­al Rea­li­ty rea­dy for take-off: In con­ver­sa­ti­on with pro­fes­sor Dr. Mari­us Swo­bo­da, Rolls-Royce

Pro­fes­sor Dr. Mari­us Swo­bo­da, Head of Design Sys­tems Engi­nee­ring at Rolls-Roy­ce, talks about his work - The Bri­tish com­pa­ny Rolls-Roy­ce is deve­lo­ping the air­craft engi­nes of the future in Dah­le­witz: vir­tu­al rea­li­ty has long sin­ce beco­me rea­li­ty in avia­ti­on. We spo­ke with Prof. Swo­bo­da about 1:1 visua­li­sa­ti­on, engi­ne health moni­to­ring, safe­ty requi­re­ments, and potholes. 

Visua­li­sa­ti­on tech­no­lo­gies in avia­ti­on: how far are we, whe­re are we hea­ding, Pro­fes­sor Swoboda?

In gene­ral, visua­li­sa­ti­on tech­no­lo­gies in avia­ti­on are con­stant­ly incre­asing and are alre­a­dy being deploy­ed in many are­as - from design through mar­ke­ting to trai­ning and ser­vices. At Rolls-Roy­ce Deutsch­land in Dah­le­witz, for exam­p­le, we are ope­ra­ting a 3D Vir­tu­al Rea­li­ty CAVE for the true-to-sca­le visua­li­sa­ti­on of engi­nes and their com­pon­ents. This not only allows a 1:1 visua­li­sa­ti­on of our pro­ducts, but also a world­wi­de coope­ra­ti­on with col­le­agues on the col­la­bo­ra­ti­ve and opti­mal design of com­pon­ents. Inte­rest and demand have risen rapidly within the com­pa­ny sin­ce the faci­li­ty was estab­lished - the immersi­ve dis­play expe­ri­ence and the prac­ti­cal bene­fits have been con­vin­cing within a short peri­od of time.

Visua­li­sa­ti­on, robo­ti­sa­ti­on, AI in air­craft pro­duc­tion: how lar­ge is the “hands-on” share?

I can only speak for our com­pa­ny here. We are curr­ent­ly working, for exam­p­le, on approa­ches for the auto­ma­tic inspec­tion of assem­bled engi­ne com­pon­ents. The real com­pon­ents are film­ed from many per­spec­ti­ves and com­pared elec­tro­ni­cal­ly with CAD design data. The soft­ware solu­ti­ons deploy­ed here include many AI approaches.

We are even fur­ther in terms of AI ser­vice. We are the pio­neers of ‘Engi­ne Health Moni­to­ring’ (EHM), i.e. moni­to­ring engi­nes in the air. What began deca­des ago is now firm­ly estab­lished with our cus­to­mers and is con­stant­ly being deve­lo­ped by us. For exam­p­le, we are incre­asing­ly using AI to moni­tor the ope­ra­ting data of indi­vi­du­al engi­nes and eva­lua­te them tog­e­ther with a type’s enti­re fleet. What we learn from an engi­ne thus bene­fits the ope­ra­ti­on and safe­ty of all engi­nes - not only retro­s­pec­tively, but also as far as pre­ven­ti­ve mea­su­res are con­cer­ned when cor­re­spon­ding trends emer­ge. We are alre­a­dy recor­ding thou­sands of para­me­ters for the latest Pearl engi­ne for Bom­bar­dier – initi­al­ly, they were only in the dozens.

Does that replace the pilot?

No - not at all. Our ope­ra­ti­ons cen­tres recei­ve the engi­ne data via satel­li­te. Our engi­neers track and eva­lua­te them - manu­al­ly and with the help of AI appli­ca­ti­ons. If mea­su­res beco­me neces­sa­ry, our experts first talk to the ope­ra­tors of the air­craft, and the respon­si­ble manage­ment in turn talks to the pilots. The final decis­i­on for an air­craft in the air is always taken by the captain.

Is ful­ly auto­ma­tic air­craft pro­duc­tion, at least men­tal­ly, clo­se at hand?

As has just been sta­ted: we can only speak about our field of acti­vi­ty. Engi­ne con­s­truc­tion is still lar­ge­ly a manu­fac­to­ry which, on the one hand, has some­thing to do with the extre­me­ly high safe­ty and qua­li­ty requi­re­ments and, on the other, with the ari­sing quan­ti­ties. We are stan­dar­di­sing to a con­sidera­ble ext­ent and are, in part, pur­suing a plat­form stra­tegy that is simi­lar to that of the auto­mo­ti­ve indus­try. Howe­ver, the level of auto­ma­ti­on is also a mat­ter of the “busi­ness case”. Plea­se bear in mind that nowa­days appro­xi­m­ate­ly 25,000 pas­sen­ger air­craft are being actively deploy­ed around the world. That is a very small num­ber com­pared to the num­ber of cars being lar­ge­ly pro­du­ced auto­ma­ti­cal­ly. This rela­ti­on will con­ti­nue: both Air­bus and Boe­ing deli­ver­ed around 700 air­craft in 2017. VW sold about 5 mil­li­on vehic­les in the same year.

Take the buz­zword of self-fly­ing air­craft: the auto­pi­lot of the ski­es has been around for a long time, it is only now that the tech­no­lo­gy is slow­ly arri­ving down on the ground. Why is the auto­pi­lot up in the ski­es so estab­lished and there’s not­hing to be “ner­vous” about, but it’s a dif­fe­rent mat­ter when we talk about auto­no­mous driving ?

Once an air­craft is up in the air, pilots are usual­ly rare­ly con­fron­ted with any chal­lenges from the imme­dia­te sur­roun­dings. On the road, howe­ver, an incre­di­ble num­ber of chan­ging cons­traints have to be taken into account for dri­ving dyna­mics (traf­fic, pot­ho­les, wal­kers, wea­ther, etc.). Sen­sor tech­no­lo­gy and infor­ma­ti­on pro­ces­sing have sim­ply not yet been deve­lo­ped enough to pro­cess the neces­sa­ry amounts of data in the car in real time and con­vert them into sui­ta­ble actions. Flight simu­la­tors for prac­ti­sing the neces­sa­ry actions have been available sin­ce the 1960s, but the first car dri­ving simu­la­tor was only laun­ched on the mar­ket around 1985 (Mer­ce­des Benz Mari­en­fel­de). This is due, on the one hand, to the fact that the flight mecha­nics are very good at describ­ing the move­ment of an air­plane and the things usual­ly run very order­ly (inclu­ding take­off, landing, gus­ting loads), but, on the other hand, the­re is sim­ply too much going on with road traffic!

As a Bri­tish com­pa­ny, you are rese­ar­ching and pro­du­cing just out­side of Ber­lin - Why? What poten­ti­al does Bran­den­burg have now and in the future?

That’s right, we’­ve been here for around 25 years and are ste­adi­ly evol­ving. Ori­gi­nal­ly, we were a joint ven­ture in Ger­ma­ny bet­ween BMW and our Eng­lish parent com­pa­ny, Rolls-Roy­ce plc. At that time, we were loo­king for a con­ve­ni­ent­ly loca­ted and attrac­ti­ve loca­ti­on with access to qua­li­fied spe­cia­lists. That was the case in Bran­den­burg. This is a place whe­re we have a very open-min­ded, com­mit­ted sta­te govern­ment, who has always given us a lot of sup­port, as well as an aca­de­mi­cal­ly chal­len­ging envi­ron­ment with uni­ver­si­ties of appli­ed sci­en­ces such as the BTU Cott­bus or the TU Ber­lin. Ever sin­ce the launch, we have suc­cee­ded in trans­fer­ring responsibility
