Trans­port re­search

New concepts for future rail transport

New con­cepts for fu­ture rail trans­port

December 16, 2021  In the Next Gen­er­a­tion Train project, DLR sci­en­tists are de­vel­op­ing new con­cepts for fu­ture rail trans­port. Here, the com­plete train fam­i­ly is unit­ed: con­sist­ing of the NGT Link feed­er, the NGT high-speed train and the NGT Car­go for freight trans­port. (from left)

Test pilots needed

Test pi­lots need­ed

September 4, 2017  A na­tion­wide re­cruit­ment drive is start­ing now and will last un­til mid-2019 to find test pi­lots who are keen to use a car­go bike mod­el that suits the trans­port needs in their or­gan­i­sa­tion.

Ac­com­pa­ny­ing re­search dur­ing the test phase

September 12, 2017  Trans­porta­tion re­searchers will ac­com­pa­ny the pi­lot project dur­ing the first two years to anal­yse us­er ac­cep­tance and to es­ti­mate its im­pact on the en­vi­ron­ment and trans­port as a whole.

Wind tunnel and structural model of the Next Generation Train

Wind tun­nel and struc­tural mod­el of the Next Gen­er­a­tion Train

April 26, 2011  The trains of the fu­ture need to be ef­fi­cient, safe and cost-ef­fec­tive. To this end, DLR com­bines skills in, among oth­er things, aero­dy­nam­ics, lightweight con­struc­tion, en­er­gy man­age­ment and com­mu­ni­ca­tions.

Us­ing wind tun­nel mod­els (coloured sil­ver in the il­lus­tra­tion), cross­wind sta­bil­i­ty and pos­si­bil­i­ties for drag op­ti­mi­sa­tion are in­ves­ti­gat­ed. A draft de­sign has been pre­pared (light lat­tice struc­ture) for the topo­log­i­cal op­ti­mi­sa­tion of the train struc­ture, from which con­clu­sions about the main load paths in the car­riage body can be drawn. This gives im­por­tant in­for­ma­tion for the se­lec­tion of the man­u­fac­tur­ing and as­sem­bly tech­nolo­gies to be used for the Next Gen­er­a­tion Train.

Next Generation Train – 50 percent energy savings in future

Next Gen­er­a­tion Train – 50 per­cent en­er­gy sav­ings in fu­ture

June 16, 2011  At 400 kilo­me­tres per hour, a silent dou­ble-deck­er – the Next Gen­er­a­tion Train (NGT) – will trav­el in­to the fu­ture and in do­ing so will re­alise en­er­gy sav­ings of 50 per­cent. In this project, the Ger­man Aerospace Cen­ter (DLR) is com­bin­ing its skills in the field of rail­way ve­hi­cle re­search. DLR re­searchers are work­ing to make the trains of to­mor­row lighter, more en­er­gy ef­fi­cient, more com­fort­able, safer and, at the same time, faster.

June 16, 2011  One-of-a-kind – the per­for­mance of high-speed trains is test­ed un­der un­prece­dent­ed­ly re­al­is­tic con­di­tions in the new tun­nel sim­u­la­tion fa­cil­i­ty at the Ger­man Aerospace Cen­ter (DLR) in Göt­tin­gen.

September 8, 2011  With this dou­ble-deck train mod­el made from car­bon-fi­bre-re­in­forced com­pos­ite, DLR re­searchers mea­sure, among oth­er things, the noise emit­ted by a high-speed train.

In ‘conversation’ with the traffic lights

In ‘con­ver­sa­tion’ with the traf­fic lights

April 26, 2011  In­no­va­tive com­mu­ni­ca­tions and po­si­tion­ing tech­nolo­gies make it pos­si­ble – cars and trans­port in­fras­truc­ture ex­change in­for­ma­tion.

Highly automated: One the touch of a button is enough

High­ly au­to­mat­ed: One the touch of a but­ton is enough

April 3, 2019  With the touch of a but­ton, the driv­er can se­lect the lev­el of au­toma­tion. Road traf­fic ac­ci­dents are of­ten the re­sult of er­rors made by inat­ten­tive, over­stressed or tired drivers. The ob­jec­tive of the EU project HAVEit (High­ly Au­to­mat­ed Ve­hi­cles for In­tel­li­gent Trans­port), in which the Ger­man Aerospace Cen­ter (Deutsches Zen­trum fuer Luft- und Raum­fahrt; DLR) played an ac­tive role, was to min­imise the num­ber of this kind of ac­ci­dents.

The car of the fu­ture

June 16, 2011  Dif­fer­ent DLR ve­hi­cle tech­nolo­gies, such as new propul­sion con­cepts or lightweight con­struc­tion, are eval­u­at­ed and com­pared with a com­put­er mod­el. Sci­en­tif­ic eval­u­a­tion makes rec­om­men­da­tions for pol­i­cy and eco­nomics.

Schlörwagen flow image

Schlör­wa­gen flow im­age

June 16, 2011  The Schlör­wa­gen was an ex­per­i­men­tal car, which caused a stir in 1939. It had an amaz­ing­ly low drag co­ef­fi­cient of 0.186. Mea­sure­ments car­ried out in the sev­en­ties by Volk­swa­gen con­firmed that the drag co­ef­fi­cient of the Schlör­wa­gen was a mere 0.15. To­day's pas­sen­ger cars have a drag co­ef­fi­cient rang­ing from .24 to 0.3; they can­not match the favourable aero­dy­nam­ic shape of the Schlör­wa­gen. This im­age shows a mod­el Schlör­wa­gen in the wind tun­nel. The tight air­flow is clear­ly vis­i­ble.

The free-pis­ton lin­ear gen­er­a­tor (FKLG) – a new kind of range ex­ten­der for elec­tri­cal­ly pow­ered ve­hi­cles

February 19, 2013  DLR re­searchers in Stuttgart have be­come the first team in the world to demon­strate the fea­si­bil­i­ty of the free-pis­ton lin­ear gen­er­a­tor, which they ac­com­plished us­ing a test bench de­vel­oped specif­i­cal­ly for this pur­pose.
