Failure of a high pressure HP turbine blade in a military turbofan engine is investigated to determine the root cause of failure. Forensic and metallurgical investigations are carried out on the affected blades. The loss of coating and the presence of heavily oxidized intergranular fracture features including substrate material aging and airfoil curling in the trailing edge of a representative blade indicate that the coating is not providing adequate oxidation protection and the blade material substrate is not suitable for the application at hand. Coating spallation followed by substrate oxidation and aging leading to intergranular cracking and localized trailing edge curling is the root cause of the blade failure. The remaining portion of the blade fracture surface showed ductile overload features in the final failure. The damage observed in downstream components is due to secondary effects.

Berlin, Germany. June 9—13, When analysing the performance of aero-engines with incomplete input data, it is often necessary to estimate the value of the missing parameters. This paper describes the work completed to develop correlations linking various turbojet parameters using a database of nearly data points. The study was limited to small single-spool turbojets with static thrust up to about N lbf.

Allison designed a new wide-chord snubberless or clapperless titanium fan and low-pressure turbine. Ten months after the programme launch, the GMA was first ground tested in mid and flight-tested on a Cessna Citation by mid It was tested at these altitudes in February at the Arnold Engineering Development Center in Tennessee and the first was delivered in May More than 3, engines have been delivered. The AE is a direct drive turbofan engine with a single stage fan, a stage axial compressor with 6 stages of variable vanes including inlet guide vanes, an annular combustor , a two-stage high pressure turbine and a 3-stage low pressure turbine. The accessory gearbox is mounted at its bottom and two single channel FADEC units are mounted in the aircraft. It has fore and aft mounting provisions for underwing pylon or aft fuselage installation.

Introduction

 А-га. - Не хочешь составить мне компанию. У меня на столе пирог с сыром. - Хотела бы, Джабба, но я должна следить за своей талией. - Ну да? - Он хмыкнул.  - Давай я тебе помогу. - Ах ты, пакостник.
