Raburn calls the Eclipse "a disruptive technology" in an industry dominated by a few big firms. The killer app of the Eclipse is its tiny engine. Williams, who designed engines for cruise missiles, has been working on reducing engine size for decades. The Eclipse engine, the EJ22, is tiny in airplane terms--85 lbs. (the CJ1 weighs 450 lbs.) and about 14 in. in diameter. But it produces a powerful 770 lbs. of thrust (CJ1: 1,900 lbs.). That's a higher thrust-to-weight ratio than any commercial turbofan engine, and it is the smallest, quietest and lightest...
...surprisingly, some critics think this set of aeronautical physics is pi in the sky. "There will have to be some miracles inside the EJ22," wrote Mac McClellan, a columnist for Flying magazine. But Raburn welcomes the skeptics. He even wears a WCSYC button on his lapel. "It stands for 'We Couldn't, So You Can't,'" says Raburn. "I've seen that mentality before. I worked in the software business. Remember what small personal computers did to those huge, lumbering mainframes?" Point taken. Is your driveway wide enough...
