Technically headed by pakistan; What does that exactly mean, if you could please explain in layman terms.
How much of the airframe design, airframe testing, control system validation, material testing is specified by PAF, if so does PAF have any experience in doing so in the field of design, testing and validation?
That would depend on the Chief designer of the JF-17 and the team allocations.
Control systems, Airframe design had CAE involvement.
Each Team had a mix of Chinese and PAF engineers working together.. taking an OJT role.
As for the last part.. THIS WAS THE PAF's EXPERIENCE BUILDER IN THE DTV of aircraft systems.
They learnt on the previous experience of their Chinese counterparts, and added their inputs..
Thats the reason many team leads were Chinese , so that they could guide the CAE engineers working under them in the aspects of aircraft systems design, testing and integration.
Technically headed mean that the projects impetus, its goals.. its deliverable and time-frame were managed by the PAF. Decisions on avionics, performance management, scheduling was carried out in co-ordination with CATIC. Think of it in similar terms to the MMRCA.. the project starts with co-ordination with Dassault..which heads most of the manufacturing.. and gradually turns to focus on HAL taking over most of the aspects.
Except in this case, the Rafale was not sitting at the drawing boards with a few rudimentary blueprints until HAL came along.. and at no point did HAL ever send manpower to Bordeux to move the Rafale along.
For the JF-17, the manpower had to be sent..to supplement the Chinese engineers ..
Team Leaders were trained to supplement and in some cases supplant the Chinese Leads who were needed elsewhere(J-10B and J-xx programs).
