Lightweight fighter: a (re)emerging requirement?

Article Abstract:

The lightweight fighter (LWF) concept appears to be gaining credence as the increasing size and sophistication of traditional fighters make them more costly and out of reach of the budgets of small air forces. Moreover, the current fleet of LWFs that were mostly procured between the 1960s and 1970s will have to be replaced by the end of the next decade. Thus, the 21st century LWF can be positioned to fill both traditional market niches: for small air forces where it can be procured at a number to constitute a sufficient force, and for medium and large air forces where it can complement the top-range fighters.

Military helicopter propulsion

Article Abstract:

Manufacturers of military helicopter engines are continuously developing new designs to improve fuel efficiency and performance. The centrifugal compressor approach, which is used in the latest helicopter engines such as the MTR390 and the T800, has been further enhanced due to advances in technology, particularly in 3D computational fluid dynamics. Standardization of helicopter engines has also become a trend due to cost factors.
