when I look at the digital cockpit of Kowsar I get so impressed . This is because I fully understand what has been involved into making each subsystem of this cockpit. I have worked in Western military aviation all my 40 year career and if you count the number of Electronic subsystems in this aircraft you realize what a mammoth task it has been to design,build,test and airworthy qualify each of them. Now keep in mind that a Western engineer sitting in a nice desk with all the data/spc sheets of every component he wishes to use (and he has at least 6 different choices for each let say microprocessor he intends to select). Compare that to the Iranian engineer sitting on his desk and having to shoehorn his design based on what he can get in the sanctioned market of Iran and he is lucky to get a translated let say Russian or chinese data sheet. Putting all the subsystem together making them work together (integration) is another story...this is all assuming that the aircraft itself is already done all the CAD drawings in place and of course the engine and landing gear and ejection seat also done (which is a whole new story all by themselves)... now the only sin that Iranians have done is that the physical external shape of this aircraft is similar to a f**king F5 and because of that this whole project is poof!....I can understand if an idiot western military observer will try to focus on this single sin and playdown this fantastic achivement ... but for all those Iranian in this forum please do not be fooled by what you read or see in the western media ...have faith and pride in what has been done (no country has ever been able to do such a feast under these condition...the closest I can think of is north korea and they are not even close)
I couldn't have said it better myself. Most people think that just because two planes look similar from the outside, they must also be similar from the inside. But this is completely wrong. A lot of planes look similar from the outside but what differentiates similar looking planes from the outside is a completely different set of avionics and powerplant on the inside. Iran's F-5's and F-14's look similar to American planes from the outside but they need regular maintenance to fly. Since they are flying today, it is a pretty safe conclusion that Iran has replaced US components with its own versions and does its own maintenance to keep them up to the original performance spec. The internals of a US F-14 and an Iranian F-14 would look very different today despite looking similar from the outside since many US parts would be replaced with Iranian components in the last few decades as Iran got better at reverse engineering. In Iran's case, without any kind of manual or guide, upgrading avionics or replacing the engines require them to know exactly how those avionics and engines are designed and function in order to do it on a level of technical self sufficiency. Trying to figure out how avionics or engines work while the plane is powered down on the ground is an insanely complicated, time consuming, and difficult process that few countries can do, and that's WITH a manual. It is easier to understand how the flight systems and engines work inflight but you can't open a plane's assembly while it's flying so you have to learn it all from scratch while the avionics are basically in ground mode and the engine is at low power which makes it harder to replicate flying conditions to build correct components. Iran managed to do it all from scratch without a manual and under sanctions. This is a lot more impressive and difficult than most people realize, especially given the circumstances of Iran's ability to acquire parts, and how few countries in the world can actually manage to understand the inner workings of a plane. Designing a plane from the outside is the easy part, you just look at it. It's the inside that's the hard part which is kept a secret and that's what Iran has mastered, so the technical feat Iran has managed is nothing short of remarkable whichever way you look at it. Iran didn't become a STEM powerhouse overnight, things like learning how avionics and propulsion work and then building their own systems is what got them there.
