Cleaning up Melmoth

Gemini Sparkle

Key Takeaways:

  • The author successfully reduced drag and improved the performance of his homebuilt composite airplane, Melmoth 2, particularly through the unexpected benefit of closing the nosewheel well, demonstrating that practical optimization can yield significant results.
  • The article expresses skepticism about the future of supersonic business jets, questioning their societal justification, the diminishing returns of extreme speed, and the practical, environmental, and economic impediments to continued speed increases.
  • Beyond current challenges, the author raises concerns about the long-term availability of aviation fossil fuels and explores the radical prediction by Burt Rutan that advancements in virtual reality may eventually render physical air travel unnecessary.

I have been flying my homebuilt for more than four years now, and have been recording performance points on almost every flight while looking for ways to reduce drag. The homebuilding community is full of stories about huge successes in drag reduction, but I think those guys must be starting with Wilgas. It turns out that if you begin with a fairly clean airplane, it’s not that easy to find ways to make it cleaner.

Mine is a somewhat old-fashioned looking airplane, seating four under a bubble canopy – I like the all-around view – like a Navion or a Meyers. If I wanted to be stylish and up to date, I missed the boat. Though it is built of composites, Melmoth 2 does not have the sweeping curves, artfully blended intersections and gracefully cusped afterbody of a Columbia or a Cirrus. It has a 200 hp engine – a Continental TSIO-360 – which seems pathetically weak compared with the 300-plus horsepower of today’s high-performance cruisers.
