(Luft) Lockheed Martin F-35 - Lightning II

[revan]

Kommt leider verspätet, aber dennoch empfehle ich die beiden folgenden Artikel. Da diese eben mit vielen Klischees zum Thema VLO aufräumen, so wird z.b der gigantische positive Effekt von ECM in Kombination mit einer VLO Plattform noch einmal erläutert und auch auf die IR Signatur der F35 eingegangen.    

Sehr zu empfehlen.

RF-IR Stealth (Techniques/Benefits)

Brief

The advantage of detecting, identifying and engaging a target while stay invisible  is undeniable,  thus for years designers has been attempting to minimize the ability of radar , RWR and Infrared system  to detect aircrafts . Aircraft with significant  low observability characteristics  embodied in are called stealth aircraft . This article will discuss some common techniques used by stealth aircraft , their benefits and clear out some common misconception....


Temperature from the exhaust pumes:

The biggest contributors of signature in mid-infrared wavelength on a jet aircraft is their exhaust pumes , reduction of exhaust temperature as little as 100 degrees can reduce aircraft infrared emission by more than haft.....


.......One very common misconception about jet engine and infrared signature is : an engine with higher thrust will always have higher infrared signature ,however that is an inaccurate assumption......

Erst durch diesen Artikel ist mir übrigens klargeworden, welch umfangreiche Maßnahmen zur Reduzierung der IR Signatur bei der F35 vorgenommen wurden.

Electronic Countermeasure (ECM)

Brief 

Ever since radar  being used in battle in an attempt to gain superior situation awareness   and guide weapons, various  techniques were created to reduce the effectiveness of those sensors. Whiles  passive countermeasure such as  Stealth techniques were invented to help military  assets hide and stay invisible from enemy’s sensors, electronic countermeasure  techniques were invented to confuse, overwhelm adversary sensors so that they are unable to track or attack friendly assets.This article will introduce and explain some common   countermeasure techniques used by military aircrafts......

RWR/ESM and Passive Geolocation

Brief:

It is undeniable that the impact of RWR-ESM on the design of modern aircraft is enormous. It has been the centre of many heated debates over the years, with many believing that modern RWR/ESM will make powerful radars and low radar cross section obsolete, as aircrafts will be instantly targeted and shot down the moment they turn on their radars. On the other hand, others believe that RWR/ESM are not much better than a warning system. The truth is far more complex than that, however.

To clear out some of the common misconceptions about RWR/ESM and passive geolocation, this article will explain how they work.

F-35 trumps F-15 in latest series of simulated dogfights

U.S. Air Force officials say F-15 "enemy jets" fail to detect or directly engage F-35s • "Feedback from unit operators has been very positive ... not just concerning performance but the ability the aircraft has with other platforms," official says......
