The record thread: How fast can you go...

[golfsierra2]

from Razdolnoye to Sukhumi or vice versa, winds set to zero, summer (20° C), non-stop flight / no AAR ?

 

Please post your best time, type of aircraft, configuration, cruising level and speed.

[Guest IguanaKing]

How about adding "fuel at start and fuel remaining" to the data? Also, for speed, do you want IAS or TAS?

[X-man]

Just gave it a try in the Su-27 and I got a time of 29 min 21 s. :joystick:

 

I took off from Sukhumi and climbed with a angel of 10 and power 10. My cruise alt was 16500 m and once there I used ABs all the way. I slowly accelerated from mach 1 to mach 2.3. I then started my descent, powering back to 8. Turned to finals and landed.

 

Config: Clean

Max TAS: 2320 km/h

Fuel at start: 9000 kgs

Fuel at finish: 3500 kgs

 

:pilotfly:

 

edit: Ok, I attached a track and ACMI of the flight :)

Mach is fine, max fuel would be suggested for a/b....

Well, one can try it with a clean MiG29A of course, but without external fuel and no landings permitted, the time will be at the end of the list....

[Guest IguanaKing]

Not sure about the Russian hardware, but the Mach meter in the US aircraft isn't precise enough for this kind of contest. We only have a limited number of aircraft to pit against each other, so we'll need things down to the last knot/kmh. Shall we go with TAS then? :D

[Corsair7662]

does using the F-5 loaded with loped external fuel tanks apply? or can I not do it :P.

[britgliderpilot]

. . . . . bugger.

 

 

Razdolnoye is the airbase that's sacrificed to give us Merzifon!

 

Gimme the co-ordinates and I'll drop an aircraft on them at minimum speed . . . . .

[Force_Feedback]

Okay, did my first attempt, Mig-29S, 3 legit fuel tanks (2x 1150, 1x1500L, mig-29 vintage), full fuel 6530 or so kg, runway takeoff from default position. Used lowest AB stage for climb to 12600m Talt (F2 view), keeping the throttle on lowest AB, full mil (accelerating with AB, then full mil, and so on). With the outer tanks empty, they went away, I continued this scoot and burn kind of thing until my 1500l tank was empty, then I kept it on lowest AB.

 

 

...and ~90km out I had less than 500kg left, so I went back to full mil, 40km out I started my descent, throttle slightly above idle, 1km from the threshold my speed was 950kph :P, so I did my infamous aerobatic routine, slowed down, dropped the gear down, and landed smoothly, I stopped at 12:26:28, with, I guess, 100kg of fuel left.

 

Starting fuel: 6530 kg

Remaining fuel:~100 kg

 

Speed, between M 1.2 and M 2.2 @ 12600m.

 

I forgot the 'ideal' altitude for the miggie in lomac, so 26.5 minutes is not that good.

[GGTharos]

F-15C,

 

12:22:24 - landing wasn't fast enough, could've shaved off 30 sec.

I used 2 fuel tanks, so starting fuel was some 20000lbs+, ending fuel at th emoment of touch down 349.

 

Highest speed was 1340kts/2.4m.

[britgliderpilot]

Hehehe . . . .

 

I just burned 9500kg of fuel in 23 minutes :D

 

Unfortunately, I overflew Sukhumi at 21 minutes at a speed of 2500km/h, so when I finally did land it was with no fuel, dead engines (not a major problem), and collapsed gear.

 

But! Even so! I did it in 24 mins.

 

Hit a max TAS in excess of 2500km/h, and I think the Machmeter in the Sukhoi was reading in excess of 2.6 at one point . . . . grin.

 

 

With more careful flying and a better approach, reckon it can get down to 20. But not now, I'm going to bed.

MAD PIZZA - Every Pizza delivery around the Krim under 30min!

 

Started in a clean Su-27 with full fuel (9400kg), flightlevel around 10.000 meter. Landed with nearly 200kg fuel left. Total: 27:04 min.

Check briefing with including receipt.

[Guest IguanaKing]

F-15C, standing start from Razdolnoye to full stop at Sukhumi, 26 minutes 57 seconds. Maximum speed 2.5 Mach (I'll get maximum TAS from the track I recorded later). Cruise altitude 37,000'. Burned about 21,000 pounds of fuel. That little trip at the mere cost of only $17,500 in fuel to the US taxpayer. :D

[Frostie]

Took an SU-25T with fuel tanks and an hourglass but unfortunately got a puncture on the Taxiway so threw my dummy out the cockpit and called it all off.:cry:

Without any crosswind, wow, that sucks big time, back to the training missions!

 

I'm thinking of doint my run again, but with 2 fuel tanks and only full mil power, maybe I can supercruise at M1.3.

Argh, it's either that, or 3 tanks and better jettison management. The miggie is a b*tch to deal with, but that makes it fun, better than the 27 or 15c, where all you do is put it in full ab, set autopilot, and go away for a piss.

I think, the total flight time is the main thing, not the max speed achieved during cruise. Considering the fixed distance between Sukhumi and Razdolnoye you can calculate the average speed.

You beat me there with 2 seconds, I have 27:06 min! :badmood:

Or not if I would have calculated like you did: I should have 26:50 ! :D

[Force_Feedback]

Oh, the 'land' times count, that is a bit unfair, as you could land with 450kph, and it would take half a minute to slow down.

 

Take-off is always at noon, so that's fixed, but then again, no 'custom' take-off positions, just the default one whith 'from runway' selected at waypoint 0.

 

In my attempt, I stopped the counter when my plane came to a complete stop, on the runway, and not when the wheels touched down...

[S77th-GOYA]

Maximum speed 2.5 Mach

 

Could you post that track?

[Guest IguanaKing]

Absolutely! I'll post it shortly. :D

[golfsierra2]

I just tried this myself, first attempt worked out so far.

MiG29S with 1500 liters centerline.

I climbed out without a/b to 12100 m cruise level and engaged a/b to 1.65 Mach until the centerline was dry, then I dropped it and slowed down to 1.2, that was the speed the MiG could maintain without a/b. 160 km out of Sukhumi I had enough fuel for a last boost to 1.6 Mach again, and 90 km out of Sukhumi I slowed down again after the first warning (fuel 1500). I landed with 800 liters internal left.

 

Total flight time: 32:30, until full stop of the aircraft: 33:08.

[Force_Feedback]

I couldn't beat my own 26:29 in the mig-29S, but I did a 26:12 in the su-27.

 

Su-27 record flight details:

 

Starting fuel: 9400kg

remaining fuel: 0kg :p

 

I did a full AB take off and climbed to 13.1xx (forgot exactly how high) m, then I accelerated until M 2.2, then eased off on the AB, letting it in the lowest afterburning setting, did some time acceleration, 50-something km out I had 300kg left, and engines were running on full military, the gas guzzlers flamed out about 2-3 km from the runway threshold, my speed was 1300-something in F2 view. Extended the big metal sail, did some horrible energy bleed maneuvers, and landed at 460kph (12:25:54), kept her straight till it stopped.

[Guest IguanaKing]

Here's the track. After viewing it though, it looks like something is hosed. My Mach meter was well above 2.4 when I went to the outside view. In the outside view, my TAS reached 2518km/h, possibly 2519. But, according to Mach at 29,000', this is actually a bit less than 2.4. I very rarely fly the F-15C, so I hadn't noticed before, but the RPM gauges are porked too. Has anyone else noticed how they read "Percent PRM", instead of "Percent RPM". And what's with the fuel flow gauges? Mine topped out at around 9200 pounds per hour, each. So, according to those gauges, I should have been able to fly to Sukhumi and turn right around and go back to Razdolnoye, on burners the whole way, and land with about 5000 pounds of fuel left. What's the point of the fuel flow gauges if they don't show actual fuel flow? :( Heh...I noticed that eye-sore again on the UFC too. A transponder cannot produce a mode A code of 8 in any of the four digits.

 

Anyway...here's the track.

[GGTharos]

You need to fly higher - and yes, the F-15 is a bit porked in many ways. I have a custom fuel flow gauge myself for dealing with this.

 

And did I say to fly higher? Go to 36000 (make sure you got good speed to begin with) and accelerate a bit there, then resume the climb to some 45000' ... dump the tanks once empty, you'll have enough fuel to make it while staying in burner all the way.

 

Though the F-15 should be able to hit a higher speed than it does in LO, it seems to be a little underpowered.

[Guest IguanaKing]

GG, I was at 37,000', dropped all three tanks when they were dry, and continued in burner until the last 5 minutes during which I was setting up for approach. I landed with plenty of fuel, and the trip was less than half an hour. According to fuel flow, I was burning 18,400 pounds per hour, which should have gotten me a round trip and given me twice the fuel I ended up landing with after my one-way trip. I wonder if maybe its a metric/imperial error in the gauge. If it were Kg per hour, that would seem about right. :)

[golfsierra2]

F-5 ?? You mean F-15C, right ? No please don't lope the aircraft, try it with the conventional loads.
