MT Propeller was founded by Gerd Muhlbauer in 1980, and he still serves as the company’s president. Most of the propellers that MT makes are a combination of beech and spruce–yes, wood–covered in carbon fiber, Kevlar, or a combination of the two. “There’s nothing new here,” said Muhlbauer, explaining that the basic design can be traced to work that Ludwing Hoffman did in 1928. What is new, in addition to improved coverings for the wood, is a trend toward more blades that are shorter; this can reduce noise significantly and often improves performance, as well. In addition, MT has expanded into nonaviation areas, making propellers for hovercraft; the largest propller the company makes is used in wind tunnels.
Germany has become a multinational place. Late in the afternoon, following lunch at an Italian restaurant run by people from Turkey, we depart on the 20-minute flight to Salzburg, Austria. Taking off VFR, we turn over the Danube River–avoiding overflight of several small villages near the airport–and pick up our IFR clearance before climbing into the clouds.
We’re asked to keep our speed up–to 180 knots until we’re five miles from the runway–and we touch down a minute or so before a Boeing 737. On the ramp, we’re parked next to a Learjet from Switzerland; next to it is a Cessna Citation XLS from Austria and another Learjet from South Africa. The co-pilot of the Citiation walks over and talks with us as we wait for the crew van to pick us up.
Tomorrow is a nonflying day. We’re going to visit Red Bull–the aviaton museum, not the energy drink! I’ll probably enjoy an extra cup of morning coffee, however….
