من فيكم لقط هالجملة " تخفيص البصمة الرادارية "
كنا نقول ونعيد ونزيد .. لكن للأسف البعض كان يكذبنا لمجرد التكذيب ..
حتى منظمين الحفل يتحملون مسؤولية الفشل التلفزيوني لهم أسبوعين بروفات برتم الحفل النهائي ليه ما قالوا تعالوا ركبوا الكاميراتوش الجديد يعني؟؟
عندنا اسوء اعلام على مستوى العالم
صورة لتاريخ
الي مايطول العنب...بيقوليارجال مواصفاتها زبالة إلى الحين عند بعض الاعضاء!
قبل مدة كم عضو يقول الطائرة مواصفاتها اضعف من طائرات اسرائيل،
ومرات يقولون لاتتقارن مع طائرة العدو الاسرائيلي، ومرات يقولون عنها بقرة ومرات جاموسه.
شيء غريب فعلا.
احد منكم لاحظ رشاقة التايفون ..
التايفون روعه
The primary advantage of the delta wing design is that the wing's leading edge remains behind the
shock wave generated by the nose of the aircraft when flying at supersonic speeds, which is an
improvement on traditional wing designs. While this is also true of highly swept wings, the delta's
planform carries across the entire aircraft, allowing it to be built much more strongly than a swept
wing, where the spar meets the fuselage far in front of the center of gravity. Generally a delta will be
stronger than a similar swept wing, as well as having much more internal volume for fuel and other
storage.
Another advantage is that as the angle of attack increases the leading edge of the wing generates a
vortex which remains attached to the upper surface of the wing, giving the delta a very high stall
angle. A normal wing built for high speed use is typically dangerous at low speeds, but in this regime
the delta changes over to a mode of lift based on the vortex it generates. The disadvantages,
especially marked in the older tailless delta designs, are a loss of total available lift caused by turning
up the wing trailing edge or the control surfaces (as required to achieve a sufficient stability) and the
high induced drag of this low-aspect ratio type of wing. This causes delta-winged aircraft to 'bleed off'
energy very rapidly in turns, a disadvantage in aerial maneuver combat and dogfighting
