Raptors and Typhoons train together during Razor Talon
Citat:
The Typhoon is a unique airframe from the F-22 pilot's perspective, offering advanced avionics, improved situational awareness and plenty of power in thrust and speed that pilots don't encounter when going head-to-head against F-15s, F-16s and F/A-18s, Langley pilots said.
"The Typhoon offers the F-22 a unique capability that sort of bridges the gap between the fourth and fifth generation," Skelley said.
Citat:Another one that might be of interest given some of the posts of recent weeks:
While the fighters are the most advanced from their respective countries, they have different abilities and advantages. The agility of the F-22 is what first jumped out to Wells, he said.
"Raptor has vector thrust: Typhoon doesn't," he said. "What the aircraft can do, it's incredible. The Typhoon just doesn't do that."
The Typhoon's strength, however, is in both carrying weapons and deploying them. With its two Eurojet EJ200 turbojet engines producing 20,000 pounds of thrust each and the distinctive wing and canard layout, the jet is strong in both its air-to-ground and air-to-air formats no matter what it's carrying. In its air-to-ground role, the jet flies with four beyond-visual-range missiles, a Lightning 3 designation pod, extra fuel tanks, [4 X 1000 (there is a slight copy error in the original)]-pound bombs and two short-range missiles. These can be aimed by the pilot looking in the direction of an adversary and targeting through a helmet-mounted system, Wells said.
"As we bolt things to the jet ... it still flies like a Typhoon," he said. "High and fast, and that's where she loves to be. She loves being at 40,000 feet and supersonic. It's brilliant in terms of performance and getting places."

Al' su zakrvili Tajfunovci sa ovim F-22  Kazu poslednji deo sage oko Tajfuna, F-22 i TVC.
“Raptor’s thrust vectoring not essential” Eurofighter pilot says in last chapter of the F-22 vs Typhoon saga
http://theaviationist.com/2013/02/21/raptor-vs-typhoon-us/#.USex6zeS-U0
Prica na temu bliske borbe i korisnosti i lose strane TVC u slucaju F-22, a i uopsteno. Treba procitati.
Citat:Typically, when time comes to decide how to achieve the required “nose pointing capability” for high thrust-to-weight ratio airplanes three solutions are on the table:
- extremely high short term sustained Angle of Attack values (characteristic of twin tailed airplanes);
- High Off-Bore-Sight Weapons, preferably supported by Helmet Cueing;
- Thrust Vectoring.
Thrust Vectoring is one of the design elements that can contribute to create a certain advantage during close air combat by generating impressive pitch and yaw rates, but only in a limited portion of the flight envelope at velocities well below “corner speed”.
However, Thrust Vectoring can also transform in a few seconds an energy fighter in a piece of metal literally falling off the sky, making it an easy prey for those who have been able to conserve their energy.
Moreover, Thrust Vector operation requires the pilot to “create the opportunity” for its usage, spending valuable time in manoeuvring the aircraft to achieve a suitable condition and managing the activation of the Thrust Vector Control.
If you are “defensive” and your aircraft has Thrust Vectoring, you can possibly outturn your enemy, but that most likely won’t prove to be a great idea: an energy fighter like the Typhoon will conveniently “use the vertical” to retain energy and aggressively reposition for a missile or gun shot. Also the subsequent acceleration will be extremely time (and fuel) consuming, giving your opponent the opportunity to tail chase you for ever, exploiting all its short range weapon array.
If you are “neutral”, when typically vertical, rolling and flat scissors would accompany the progressive energy decay, similarly performing machines would remain closely entangled, negating the opportunity for Thrust Vector activation.
If you are “offensive”, probably stuck in a never ending “rate fight”, Thrust Vector could provide the opportunity for a couple of shots in close sequence. Make sure nobody is coming to you from the “support structure”, otherwise that could be also your last move.
Talking of twin tailed aircraft, Angles of Attack in excess of 30-35 degrees are capable of creating drag conditions unsustainable no matter the engine/airframe matching, and developing energy decays intrusive of the tactical flying but also of the flight control system protections. Roll rates would also deteriorate at the higher values of AoA and target tracking ability would quickly decay.
Eurofighter has decided to develop for the Typhoon High Off-Bore-Sight Weapons, supported by Helmet Cueing, to retain energy and target tracking ability while manoeuvring WVR (Within Visual Range) at relatively high but sustainable Angles of Attack. For those who may require some additional AoA, the “Strakes” package is progressing well and soon it will be offered to Typhoon’s Customers. Nevertheless, Strakes is not purely about extreme AoA, but also suitable Roll Rates and manageble energy characteristics. Because in the European way of doing things, an all round balanced solution counts more than a single eye opening performance.
It is a fact that against Eastern produced fighters provided with Thrust Vectoring, throughout the years the Typhoon has showed an embarasing (for them) kill-to-loss ratio.
It is a fact that after some initial encounters between the Raptor and the Typhoon, the situation appears of absolute equity. Too early to say if it is the Helmet Cueing or the Thrust Vector, or how much tactics and training are a player in all this. For sure, we are facing two impressively capable machines.

где се тајфун борио против источних авиона са ВКП...
сем у индији где су их индијци ваљано испрашили са сушкама....стим да сушка има много мањи однос потиска масе у односу на тајфуна....
Баш ме интересује оћел прихватити некад ови европејци окршај са сушкама 35, пошто су амери са крептором одбили пре пар година....
милсим да би и миг 29 са ВКП одвалио тајфуна 1 на 1....ко што је прошао и Ф16 са обичном мигушком 9-12Б....
