Are radial compressors more subject to FOD? Paul Possibly not - We were working with a APU having a radial compressor.The manufacturers rep mentioned that one had swallowed an engineers flashlight and showed no damage when it was stripped down Craig |

Air Breathing for VTVLo
Peter Fairbrother writes:
Talking of models, I used to use Jetex "augmenter tubes" when I werre a lad. They "captured and entrained" air with the the Jetex exhaust, and heated and accelerated it (supposedly!. Long story, but they did actually work, and far better than the static figures show when at speed and tuned up). Do a google on "air augmentation," or look up the word "entrainment" in a good dictionary. -- Gordon D. Pusch perl -e '$_ = \n"; s/NO\.//; s/SPAM\.//; print;' |
