The Falcon takes off on its mission

The Fal­con takes off on its mis­sion

March 17, 2021  The Fal­con flights help to bet­ter anal­yse the cur­rent­ly large­ly clean at­mo­sphere, which is on­ly slight­ly pol­lut­ed with emis­sions from in­dus­try and trans­port, in­clud­ing avi­a­tion. This gives re­searchers a unique op­por­tu­ni­ty to bet­ter un­der­stand the ef­fects of in­creased emis­sions pri­or to the Coro­n­avirus lock­down.

November 24, 2021  With 10 air­craft and he­li­copters, DLR's Flight Ex­per­i­ments Fa­cil­i­ty op­er­ates the largest fleet of civil­ian re­search air­craft in Eu­rope. The Flight Ex­per­i­ments Fa­cil­i­ty sup­ports in­ter­nal and ex­ter­nal users in plan­ning and con­duct­ing their flight ex­per­i­ments. These flight ex­per­i­ments ei­ther use the air­craft as a plat­form for re­search or con­sid­er the air­craft as an ob­ject of re­search.

December 21, 2018  The Fal­con re­search air­craft ar­rived at DLR in 1976 and has proven its worth in nu­mer­ous sci­en­tif­ic re­search mis­sions and cam­paigns world­wide. Its best-known flights were car­ried out in April 2010, when the erup­tion of the Ice­landic vol­cano Ey­jaf­jal­la­jökull brought large parts of the air traf­fic over Eu­rope to a stand­still. In record time, the Fal­con was con­vert­ed and cer­ti­fied for use over Ice­land, Eng­land and Ger­many. As the on­ly air­craft in the sky, the Fal­con made sev­er­al mea­sure­ment flights.

January 2, 2019  This im­age shows AT­TAS with a changed pro­file. In 1987 a por­tion of the right wing was equipped with what is known as 'lam­i­nar glove'. A fi­bre-glass re­in­forced com­pos­ite glove was placed on the orig­i­nal alu­minum struc­ture. DLR re­searchers in­ves­ti­gat­ed whether longer lam­i­nar flow pro­files would be pos­si­ble in com­mer­cial air­craft as well. If so, the re­sis­tance and thus the fu­el con­sump­tion could be re­duced. In­frared cam­eras mea­sured the lam­i­nar-tur­bu­lent bound­ary lay­er tran­si­tion.
