في جزئية تبريد المحرك ..
هذا ما اعنيه بسوء العزل الحراري ( في حالة التايفون ,, أثر ذلك على احترار البدن الملتصق بالمحركات .. نتج ذلك بسبب عدم وجود تبريد كفؤ داخلي كون محركات EJ200 لديها قناة تبريد واحدة )
بينما تباهي الرافال في الجهة الاخرى بكون محركها يحوي قنوات تبريد مزدوجه (Dual Cooling Channel ) وعزل افضل لحرارة البدن
Snecma is developing the M88-2 Stage 4, which has the same thrust as the standard M88-2, but incorporates improvements aimed at extending the service life of the engine and reducing fuel consumption, which Massot says "will also reduce operating costs significantly". Another benefit will be to improve the duration of the low-level penetration missions.
The changes include the introduction of three-dimensional high-pressure (HP) compressor and turbine blades, blisks (one-piece blades and discs) improved thermal coatings on the HP turbine, and advanced cooling channels for the combustion chamber. The Stage 4 development will be ready in early 2001 and the modifications will be retrofitted to the M88-2. It will power the 48 Rafales ordered in the Government's multi-year procurement plan.
