I think you may be confusing things.

 

RAZBAM put out a poll asking if we wanted an AV-8B or a GR.5/7/9. The poll came out in favor of the GR Harrier, however due to problems with documentation and systems modeling, it was determined the GR Harriers couldn't be done accurately enough, and so with an apology they stated they'd be instead doing the AV-8B(NA), with provisions of doing the AV-8B+ soon after ED's implementation of ground radar. I've heard absolutely nothing about the GRs being back in the mix.

 

Here you go.

 

Gents:

As many of you are aware, i started a Harrier poll trying to decipher what the community was after "harrier wise", not surprisingly the Gr7/GR9 version was the absolute winner.

BUT, we stumbled into a brick wall, a wall that might put the Gr7/Gr9 at least 2 years behind..and that is weapons systems.

As you may know, the British version of the Harriers used a set of recce/targeting pods that are not available in the sim, being these the DJRP, Sniper and TIALD (which most if not all of it´s operational manuals are still classified). Not to mention also a pod carrying countermeasures in one of the 3 belly stations. Implementation of these pods could take us longer than expected, and i would really like to get a Harrier beta this year (fingers crossed).

I just wanted to be honest with you, no BS statements will come from us, this is the current situation and i put it out as it is.

So..as our 1st Harrier pack, we are going to create the AV-8B Night Attack version, this will allow us enough time to create the other system pods as we can get info on them and implement them in the sim.

So the road map would be AV-8B Night Attack followed by the GR7/GR9 versions and hopefully the AV-8B Harrier II Plus after at the end.

Best regards

Question about the harrier!

 

Is top speed usually limited by engine power/drag or Vne?

 

The harrier has lots of power [citation needed] and is designed for subsonic flight which makes me think it might start acting up as you approach high subsonic speeds.

 

At the same time, it has swept wings and a flying elevator so maybe it doesn't mind high Mach numbers?

DCS modules are built up to a spec, not down to a schedule.

Engines like the Pegasus, even though it's not a high bypass, the inlet diameter is very big, if you fly too fast, the air intake can't control very well the amount of air going into the engine and you can have a compressor stall. This also happens to airliner engines, they don't have the inlet like the F-15 (Intake ramps), which reduces the airflow and speed of the air before hitting the low pressure compressor stage.

 

Aircrafts like the A-10, the wings are big, the vertical stabilizers and etc produce a lot of drag, and also the efficiency of the straight wings is VERY low, the the aerodynamic efficiency is low, i.e it won't be affective at high speeds, so it is limited to low speeds because of the engines and the drag as well.

 

Commercial planes, especially with the high bypass engines can reach high speeds due the huge amount of thrust that they produce, but if they go fast, it will have a compressor stall. Jet engines have Variable stator vanes just after the first stage of the low compressor stage.. it basically controls the airflow and reduces the air speed. (Intake ramps reduces into a subsonic speed).

 

Very basic explanation but you can understand more or less what happens..

Jet engines have the static thing just after the first stage of the low compressor stage.. I forgot the name, it basically controls the airflow going to the high pressure compressor (core), by "changing" the angle of the "blade". (Sorry I forgot the name of it).

 

The Pegasus is definitely a high bypass engine. about 60% of the thrust is produced by the cold section (forward nozzles) with the remaining 40% coming out of the hot section (aft nozzles).

 

As for the wing, a straight wing is very efficient at doing what wings are supposed to do, create lift. Aerodynamically, if you want high subsonic speeds and large lifting capacity a mildly swept wing is ideal which is what I think you are trying to say.

 

The name of the parts you are referring to in the engine is the Variable Stators. That is what controls flow into the engine for optimal performance.

As far as I know it's not a high bypass engine, according to what I've found. Just look at its bypass ratio. When a looked at a diagram of that engine, I find it a bit weird honestly, there is a big bypass going into the first nozzles, and the first pair of nozzles, the air is from the low pressure compressor stage (fan - cold part of the engine). But when I looked at the specifications, it says it's not a high bypass engine.

 

I could be wrong, but I don't think it is a high bypass engine, feel free to correct me.

They call it a vectored thrust turbofan... marketing.

 

Bypass ratio is 1.2

I think I'm in love with the harrier flight manual :lol:

 

https://publicintelligence.net/u-s-navy-natops-av-8b-harrier-ii-flight-manuals/

 

The aircraft has proven to be an efficient manhole cover remover although it displays no discretion in depositing them after removal.

 

V/STOL aircraft are particularly adept at creating their own FOD and then ingesting it.

 

On a more serious note it turns out the harrier definitely does not like going fast. 0.8 Mach is generally considered 1G Vne. 0.72 Mach is safe for maneuvering.

 

The main issue with exceeding Vne is uncommanded roll due to shock induced flow separation over the wings (it doesn't always happen to both wings at once). No mention of Mach Tuck which is nice.

Nice Prowler

Looking forward to this one. Want to show my B in Law who flew for both VMA-513 and 231. Has over 3000 hours in the Harrier. Hopefully can get his stamp of approval.

I was in Art of the Kill D#@ it!!!!

Nice! I'm starting to go a little nuts here (more so than usual...) trying to be patient (yeah, if patience is a virtue I've never been virtuous in my life!) waiting for some of these great planes to be available for purchase... Please lord, give me strength!! I... just... have... to... buy... something... soon! :D

Next six months releases are going to be a cause of divorce for me! :lol:

 

Just have to hope she doesn't take half your modules when she goes!!

 

 

 

While I may not be married, I think my wallet might leave me after all these modules arrive.

Well, I don't know about the modules, but if she takes away the trackir and the warthog I'll be effed!!!
