Astra BVRAAM

Didn't see this one when i replied....
By airspeed do you mean subsonic combustion in ramjet....?

Yeah, Subsonic flow and Supersonic flow of air in combustion chamber.

In this case can we called RAMJET the engine of the nazi V1 cruise missile ?

 

[BON PLAN]

I think the main difference between RAMJET and SCRAMJET is that in the first one the air flow speed is reduce so as to be subsonic before injecting the fuel (the missile can be subsonic or supersonic). For the SCRAMJET the air flow remains supersonic (so the missile is supersonic or hypersonic).

I think...

That's pulse jet. But RAMJET was first proposed by Hitler's scientist I believe.

Okay... that's what i thought....airspeed is basically the aircraft speed...so, can't be used as speed of combustion....

 

[Chinmoy]

No , by an Russian scientist Yuri Pobedonostsev, chief of GIRD's 3rd Brigade, carried out a great deal of research into ramjet engines .

Yes. But I believe before him Albert Fono proosed and even designed RAMJET. Anyway the time line for its study is almost similar for all.

Dear Sirs, how the missile's electronics , most of which are stored for years ,get their power ? Is there any service intervals to change the batteries ? I am a novice to this topic, please clarify.

Molten-salt battery - Wikipedia

en.wikipedia.org

Thermal batteries use an electrolyte that is solid and inactive at ambient temperatures. They can be stored indefinitely (over 50 years) yet provide full power in an instant when required. Once activated, they provide a burst of high power for a short period (a few tens of seconds to 60 minutes or more), with output ranging from watts to kilowatts. The high power is due to the high ionic conductivity of the molten salt, which is three orders of magnitude (or more) greater than that of the sulfuric acid in a lead–acid car battery.

Astra Mk1 BVRAAMs, Now Operational with IAF

India’s first locally developed, Astra Mk1 Beyond Visual Range Air-to-Air Missile has gone operational in Indian Air Force (IAF) in limited numbers was confirmed by Indian Air Force (IAF) chief, Air Chief Marshal Rakesh Kumar Singh Bhadauria, after months of media speculation about IAF getting the first batch of 50 Limited Serial produced Astra Mk1 that was ordered by IAF, has now confirmed it and also it now operational which clears it to be equipped to be carried by the frontline Sukhoi-30MKI jets. IAF and Indian Navy have recently, also placed orders for 250 more Astra Mk1 BVRAAMs. Production constraints is been addressed at a rapid pace as more and more jets will be enabled to be equipped with Astra Mk1 BVRAAMs in near future. Tejas Mk1A and Mig-29K/Mig-29UPG are next in line with the later Mirage-2000 fleet also to get Astra Mk1 BVRAAMs. idrw.org has been told, Su-30MKI Squadrons deployed all over India will be receiving in Phases, must require software upgrades for integration between the missile with the Fire Control Radar (FCR) and the Mission Control computer (MC) onboard each Su-30MKI by HAL Engineers in next few months so that pilots can be trained and practice to use new BVRAAM Training rounds before next batch of AAMs starts arriving. Astra Mk1 BVRAAM is, found to be equivalent to the Framed American AIM-120C5 AMRAAM in terms of range and capacities. India’s DRDO is also working on Astra Mk2 with double the range, and with better Electronic counter-countermeasures (ECCM) that will put it into the same league as American AIM-120D (originally designated AIM-120C8).

May be few people here could now lay in rest after incessant crying.

Mk.1 was probably more of a test run for Mk.2 anyway.

 

[lcafanboy]

288 Astra MK1 missiles on the way....

Are you referring to a member whose name starts with V?

Anyways, I won't trust this report of IAF orders of 250 more Astra until I see a better source than IDRW, though I believe that the order is in final stages.

Why is it costing this much? Or is it comparable to other similar A-to-A BVRs?

Refer to other BVR missiles sales some the world. Japan & Australia bought Aim-120C7 for $2.3 million each.

Astra ₹7.5 crores convert to $1mil... Derby & R77 stock models are cheaper.

Tejas carrying 6-meteors will cost as much as 2 Tejas!

 

[johnq]

Astra missile's maximum range (when launched from 15 km altitude) is 110 km vs 90 km for R-77, while its maximum speed is mach 4.5 vs mach 4 for R-77. The R-77's rear grid fins result in more drag vs the Astra's rear fins. The R-77 is also a 2 decade old missile, and there have been improvements in missile technology since then, even within India, so I am not surprised that the Astra outranges the R-77 in spite of it being lighter. The hardware has also gotten lighter due to advances in materials and avionics technology.
Astra is also more advanced in terms of target discrimination by seeker, 2 way datalink, and counter ECM capabilities.

Having said all that it is equally interesting to consider what Pakis will be sending towards us obsolete mirage3 or MIG 21 Chinese copy. Thus, putting meteors to shoot these does not make sense.

Yes we should reserve our old Russian missiles for these Mirages and MiG copies of PAF and PLAAF.

Correct. Plus smokeless & low IR.

These stuff bring up the price. But we can expect some reduction once its fully adopted & maintenance, storage facility etc. are properly set up.
