President unveils 1st domestic turbojet engine
The engine, named Owj (Zenith), was unveiled by Dr Rouhani in the presence of Minister of Defence Hossein Dehqan and a number of officials, scientists and experts of the ministry.
Owj, which is one of the most complicated aviation products, was built without any kind of foreign participation, either in the field of knowledge or software and hardware.
The Defence Minister said that this achievement puts Iran among the eight countries that have the knowledge and technology of these kinds of engines.
The first domestic turbojet engine is capable of operating at an altitude of 50,000 feet and has got various systems.
Regarding the engine, Minister of Defence Hossein Dehqan said that this turbojet engine puts Iran at higher ranks in the region and the world, adding: “Increasing national confidence in Iranian youths’ technical knowledge, attempting to accelerate the process of defensive developments to protect our country’s airspace and national interests, and also increasing inspiration and hope through an Islamic model, are the distinctive features of the major achievements of the turbojet engine”.

这个很清真。
貌似就是山寨或改进的F-5的发动机，原准型号貌似J85吧？！
据说J85的许多数据甚至还超过昆仑？

据说J85的许多数据甚至还超过昆仑？
看什么数据了怎么去对比了，一款60年代的发动机，翻修寿命的确很长，能到2400小时，推重比挺高，达到7.32，然后加力推力才2.3吨级，据说昆仑改型的加力推力超过8吨，寿命2000小时。附一个昆仑的性能，真假自辩
昆仑1加力推力7.15吨，推重比6.21
昆仑2加力推力7.65吨，推重比7.0，据说改进后能超过7.4
昆仑3加力推力8.7吨，推重比8.05

2吨的小推力涡喷不好比。

2吨的小推力涡喷不好比。
昆仑热端寿命>1500，冷端寿命>3000，最大加力推力8X千牛，推重比8一级.
推力越大，推重比大比较难！所以先必须做好小的发动机。很多人主张航发应当像美国那样形成GE和PW的竞争机制，否则路越走越窄！发展越来越慢！说这话的网友好像来自陆航！
先做好小发动机，然后呢.......

我也主张发动机和飞机各分两个集团进行竞争。

个人认为不是先做好小发动机，而是大、中、小都得均衡发展。体量不同，很多技术细节是不同的。比如某些部件，小到一定程度时可以忽略弹性，按刚形体进行设计，但是大到一定程度，不考虑弹性是注定吃亏的。

为何加力涡喷普遍细长？而加力涡扇普遍短粗？哪位大佬能给个RD33、WP13、J79、F404的包括尺寸在内的性能参数对比表？
