An F-15 with Phoenix missiles?

Radar cross section trainer. Huh, I didn't know that was how they did that.

I don't know what the white w/dark nose is, I'm guessing some kind of ECM pod but I can't see enough of it to figure it out. That's a weird setup...it looks like an F-15A with conformal compartments?

I don’t know what they are, but I’m pretty sure those outboard missiles are NOT Falcons. Falcons have a detached trailing fin and much smaller forefins than that. They’re twigging my memory hard, but I can’t find a cross reference.

I wonder why they're not presenting the turbine fan blades in the engine nacelles? I thought those were a pretty important part of RCS?

Good find. mlmp08 posted:I had the same thought and wonder if they have a separate test facility to look at fan blades in motion. They have many facilities. That one is probably used for the weird angles that are tough to replicate elsewhere. Godholio fucked around with this message at 20:53 on Sep 2, 2018 |

mlmp08 posted:I had the same thought and wonder if they have a separate test facility to look at fan blades in motion. As mlmp08 alluded to the thing about the fan blades that causes them to have a “high RCS” is not their geometry really, it’s their Doppler returns. The fact that it is moving at a rate characteristic of its engine and it is ducted back toward the source makes it such an important reflector. Really the RCS head on of a fighter with a straight tail is probably smaller than the side profile, but the Doppler shift will give it away. While I’m sure they do engine on measurements, I would guess that they’re done in flight test or from limited angles versus a static mock up. You will know the gain from your Doppler shift versus frequency based on intrinsic properties of a radar system. Stimson’s intro to airborne radar is a good text for this.

We would occasionally see fighter jets take off/land when I was working air-medical in El Paso. Dudes were always inverted.......

The addition of triangular sonar reflective plating to submarines during the Cold War was a major advantageous development for the fleet, in some uses making them completely invisible to enemy detection. Interestingly enough, the same research into acute-angle reflectation would be later used to spur the designs of many of the stealth fighter jets in production today.

Ehhhhhhhhh I mean yea shaping is an important thing but there’s a lot more to EM waves versus acoustic waves particularly when you’re dealing with wavelengths from HF -> mm wave versus sonar which is rather limited in usable bandwidth
