This is something people with (nowadays so common) turbos in their cars should remember (although most don't know it): You should idle the engine a bit before stoping it, so the turbine has some time to cool down. (The most common problem: stoping at a petrol station after going for some time at full throttle). AFAIK Porsche were the only ones that have build an extra electrical motor to turn the turbo after shut down. As car turbos get turned only by aerodynamic forces it is much more difficult to add an extra motor than with gas turbines or jet engines (that allways need an gear box to get started - execpt perhaps the model engines) CU, Christian -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (MingW32) iD8DBQFDHeDllhWtxOxWNFcRApTbAJsFFRBXUU9G3BvSTHuz0+BBiNb7+QCgkLyh xiMR6GhaeSzVF0X+sMueXno= =2J3g -----END PGP SIGNATURE----- _______________________________________________ Flightgear-devel mailing list [email protected] http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
