Has Lycoming got a diesel?

Tuesday, February 18th, 2014

Lycoming isn’t saying much, but General Atomics Aeronautical Systems has said several times that it is testing a 205-horsepower Lycoming DEL-120 diesel engine on one of its military drones, the Improved Gray Eagle. Lycoming has said in the past that while it has shown interest in development of diesel engines, the time isn’t right. That hasn’t changed. AvWeb’s Paul Bertorelli says Lycoming may just be republishing the DieselJet FIAT 170-horsepower engine intended for cars as a 205-horsepower drone engine. The need for a new engine, he says, was driven by the sale of Thielert, the previous engine provider for the Gray Eagle, to China. The U.S. Army doesn’t want to depend on China for its military engines. While Lycoming’s (Fiat’s?) drone engine gives Lycoming additional experience, it may continue to wait until diesel engines for manned aircraft look like a good business decision. This all came up a few days ago after Andre duCros published an item  in his DieselAir newsletter.

Cessna’s test 182 JT-A lands in field

Thursday, August 22nd, 2013

Cessna has confirmed its 182 JT-A powered by an SMA diesel engine landed in a field 30 miles west-northwest of Wichita Aug. 21. It is used for research and development of the diesel-powered 182. No details as yet but a local television station reported an engine failure. The pilot onboard was not injured and apparently was alone in the aircraft. Television news footage shows the aircraft intact amidst tall grass. The aircraft was on a certification flight. It was one of the steps needed to complete certification before deliveries can begin. Congratulations to the pilot for a great emergency landing.

Diesel market special report in “Pilot”

Tuesday, July 23rd, 2013

Just as the deal is announced between AVIC in China, and the bankrupt Thielert diesel engine company in Germany, AOPA Pilot has published a special report on where diesels are headed. There are several general references to a deal to bring Thielert out of bankruptcy in the article, as well as comments on Continental’s plans to stake its future on sales of diesel engines to the world market, if not so much to the United States.

Continental is owned by the same Chinese company, AVIC, that acquired Thielert. The deal means that Continental suddenly can offer a complete line of diesel engines. Before its bankruptcy, Thielert even had a 350-horsepower diesel on several Cessna 206 aircraft, but development ended with bankruptcy. Continental now has access to that technology, along with the smaller engines. Continental certified in December its 230-horsepower diesel based on technology it bought from SMA, the company that used its refined, second generation technology to win the trust of Cessna Aircraft for the Cessna 182 now nearing deliveries.

Check out our special 3,000-word report on where diesel technology is headed in the August issue of AOPA Pilot already released as a digital edition, and reaching mailboxes now.
