11. New staff have been employed to assist in obtaining EASA DOA Approval.

10. Enquiries continue to be received from all over the World for many diverse applications

9. Two well respected manufacturing companies, one in the UK the other in the US are working on building DAIR-100 engines under licence. Production is anticipated late in 2006 or early 2007.

8. The company Luscombe successfully flew for 125 hours on Jet A1 before the engine was removed for evaluation and continued testing.

7. Engines were provided to the U.S. military. These engines had to have a cold start capability at 15,000 ft altitude and high temperature operating capability. One was successfully tested in the Yuma desert at ambient temperatures of 100 deg F.

6. The company has applied for CAA Design Organisation Approval.

5. Several airframe manufacturers are testing DAIR - 100s in their aircraft.

4. Aircraft and airship installations are now flying successfully.

3. The next stage of development is to turbocharge the engine and increase power to 150HP.

2. Weslake Air Services near Hastings are now building engines under licence for Diesel Air Ltd.

1. The Airship Technologies AT-10 airship first flew with DAIR-100 engines on 28th March 2002. The engines mounted in ducts on either side of the gondola produce in excess of 8lbs static thrust per horsepower. The engine nacelle contains air/liquid heat exchangers of sufficient capacity to radiate engine waste heat at full power with no motion-generated airflow over the engines. (Two water radiators and one oil radiator). The engines are not fitted with either air-to-air intercoolers for cooling induction air or secondary exhausts for maximum power delivery and are effectively de-rated to 85 hp at 2400rpm as a result. The AT-10 does not have a requirement for full DAIR-100 power, however the compact size of the engines coupled with their jet fuel burning capability and acceptable weight place them as the ideal engines for this application. From an expanded view of the rear of the engine (see pics) the auxiliary compressor and electrical generator can be observed together with the remote oil filter. The fly by wire controls for the airship are power assisted with compressed air. The large generator provides plenty of excess power for any on-board electrical installations.
