Updated prop disks, DP and flight model for Baldy's Barracudas!

Updated prop disks, DP and flight model for Baldy's Barracudas!

A good day to everybody! :wavey:

I just uploaded updated 4-blade propeller disc textures for Mike Feilden's, a.k.a Baldy, Fairey Barracuda MkII, MkIII and AI version. Both full disc and single blade textures to choose from.

When I saw the flight model and damage profile derive from the stock CFS2 Avenger, I tried to taylor them more closely to the Barracuda historical specs. I started out by removing stock break effect model numbers to avoid generation of clones when shot down. I then deleted systems and effect boxes for inexhisting TBF wing guns, bomb bay and lower gun turret. I replaced rear gun data from the original single .50" to dual .303" Vickers K guns and adjusted muzzle flash locations. Finally, I replaced GC's British bombs with better sized William Dicken's Beaufighter 250/500lb GP bombs and included a Green Ghost's DAP gauge-controlled exhaust effect.

For the MkIII I took advantage of the hardpoints left free by not carrying the 1,600lb Armour Piercing bomb, carried by the MkII, and added an extra pair of depth charges, fitting more the MkIII submarine hunting specific mission.

In the airfile I removed the stock TBF radial engine (record #505, Engine CFS/FS2000 Piston Engine) and replaced it with the Barracuda real-life powerplant, a 1,645 hp Rolls-Royce Merlin 32, single-stage, two-speed supercharged V-12 engine, which also equipped the Supermarine Seafire LII. In record #1101, "Primary Aerodynamics", I added the missing flap lift and the opening of the rear gunner canopy will add a slight drag with a loss of speed.
The Fairey-Youngman flaps equipping the Barracuda were designed to be operated also as dive brakes, set at a negative angle. When the prototype, equipped with a more conventional Albacore-type tail unit with a low-set tailplane, was tested, the flaps deployed as dive brakes created an air wake which caused tail buffeting, loss of elevator effectiveness and vibration at high speed. The result was a redesigned tail in which the taiplane was strut-braced high up on a taller, narrower fin. Hence the rather odd shape of the Barracuda.

Unfortunately, this animation was not molded in this CFS2 model and the spoiler key activates the rear gunner, instead... So, watch your airspeed when dive bombing the Tirpiz!

Tested in CFS2 with these mods, Baldy's Barracudas match closely historical performance and top (poor) speed reported in Aerospace's "British Warplanes of WWII". The Barracuda was always judged rather underpowered, but, in spite of it, it did well during WWII, a tribute to the skilled pilots who flew Barracudas in combat.

Although you will find a separate airfile for each of Baldy's Barracuda models including the AI, all of the airfiles included in this package will perform fine as AI aircrafts, as I included in all of them MOI values (Moment Of Inertia Values, airfile record #1001) reduced 50% from the aircraft.cfg values for good AI performance.

MOI values represent the amount of force needed to make an aircraft yaw, roll and pitch, in CFS2 aircraft.cfg values are used for the player's aircraft, while for computer-controlled (AI) aircrafts airfile values take precedence. While the player's aircraft may perform beautifully with aircraft.cfg values, usually they are way too high for the simulator engine to handle while governing all other aircrafts, resulting in AI planes behaving badly during missions like refusing to dogfight, drop bombs, dive bomb, do torpedo runs and such. Lighter MOI values will render AI planes nimbler and more willing to play the role assigned to them in missions or execute your radio commands during combat. It's uploaded in the "CFS2-Other" section.

Enjoy!

Kelti,

Congrats on another masterpiece. If you have any further log in problems, please bring it to my attention earlier so your frustration level doesn't rise, my friend! :ernae:
 
Great work KH although I doubt whether she could carry six depth charges - after all she could only carry three 500lb bombs

cheers

baldy

Hi Baldy!

Thank you again for your beautiful Barracudas! I only applied the armament description reported in 1998 Aerospace Publishing's "British Warplanes of WWII", my primary source of info for working on CFS2 British addons. I usually do not like fictional makeups, so I duly check my books before making any change to an aircraft, since I am sure its original designer searched thorugh historical records as well.
If it weren't for CFS2 infamous hardpoint limit I would have added an extra pair to the MkII, too.

I quote "Barracuda MkII - Armament: two 0.303" (7.7 mm) machine guns, plus one 1,620 lb (735kg) torpedo, or up to 1,600 lb (726kg) of bombs, or six 250 lb (114kg) depth charges, or 1,640 lb (744kg) of mines." After all, 6 x 250 makes 1,500 and if she could carry three 500 lb bombs she could carry six depth charges just as well. Unless the depth charges you built and added to your Barracuda payloads are heavier than 250 lb each, then you are right and I screwed up. Is this the case?

Cheers!

Mk 53 depth bomb

Hi KH

I've checked back - the Mk 53 weighed 325 lb - so six would be 1950 lb - too heavy - but if you want to switch to 250 lb depth charges that's fine

baldy
 
That's too much!

Hi Baldy,

I agree, I screwed up, that's way too heavy. I was convinced those Mk 53 were 250 lb each.

Why don't we leave the MkII with four heavy depth charges, since there's no possibility to add two extra hardpoints anyway, and we change the anti-sub MkIII payload to lighter weapons?

Providing I do not want to use old Ground Crew's RAF weps that are badly oversized, which depth charge available in SOH armoury do you suggest I should use?

Cheers!

Some weapons info

Baldy, KH

Excellent work on that Cudas!:applause::applause::applause:

Here goes some Barracuda specifications that might be useful for adjusting DPs

View attachment 70528

There were many others experiments done on the limited Cuda capacity of transport.

Like floats to carry agents
View attachment 70528

Or airborne lifeboats
View attachment 70530

But I think those were only left us just that: experiments.

If someone succeeds in attaching a parachute to depth charges, and making them fall "slowly", It would be a great addition to make an airborne lifeboat. Although it CFS2 engine terms it would be, act and sink like a bomb, it could be used with a trigger to make the same lifeboat (now as a ship) appear in the sea for air-sea rescue operation missions.

Cheers, Discus
 
Depth charges

haven't been able to find other depth charges other than Jim Jacobsen's for the Martin Mariner and they're about the same as mine - as you say the GroundCrew weapons are over sized - now if some one has got any pics and dimensions for the 250lb depth charge ( I haven't been able to find any ) I'm more than happy to make some.

as to the lifeboat or the passenger pods - strictly on-offs iI think

Hi Baldy,

the Cuda specs posted by Discus (thanks, Discus!) confirm the 6 x 250lb depth charge payload and I found more info in the same book I wrote about above.

The Barracuda cutaway drawing, and I'll try to post a scan later on, states the depth charges were the Mk VIII type, and it shows the straight, long cylinder type with no stabilizer winglets. I assume the Mk VIII's weighthed 250 lb, then, but the only one available looking like the Mk VIII is, ....sigh! :rolleyes:, Ground Crew's or Alphasim's old RAF weapon pack where it looks too small.

I know you made the MkVII already, perhaps you could make a Mk VIII as an update of Ground Crew's model by downsizing it a little? It would look great on your Albacores and on the nice Swordfish models out there!

Then we have another problem here, since Discus' specs state Barracudas were armed with a single, fixed 0.303" machine gun :icon_eek:, while I have nothing showing it. Now what?

Below: how she looks with Alphasim's RAF aerial depth charges.

Well.....

When all else fails, use DPEdit, add a single gun barrel pointing forward, and forge ahead !!!
 
Barracuda

Nothing I've read says anything other than 2 x 303s in the rear compartment and those AlphaSim D Cs look OK so I'd leave things as they are

Barracuda & Skua

From Putnams British Naval Aircraft since 1912 - Owen Thetford:-

Blackburn Skua-
Quote "Armament: Four Browning machine-guns in the wings and one manually-operated Lewis gun in rear cockpit." Unquote
The Skua was also the first FAA aircraft to claim an enemy aircraft shot-down during WW2, which was a Dornier Do-18 flying boat off Norway.

Fairey Barracuda-
Quote "Armament: All marks had twin Vickers 'K' guns in rear cockpit." Unquote
 
Just read some more of the book from where I got the Cuda specifications. This is what I´ve found about the foward firing gun:

"A single fixed Forward firing 0.303 machine gun intended for the pilot was never fitted. A single gun was supplied for the observer and fitted to all Mk.ls and a number of Mk.lIs but was removed once with the squadrons."

Here is some more info about the Cuda weapons:
"A twin-gun mounting aft for the TAO was an adaption of the Albacore fitting. The TAO fired his guns from a standing position using, on early aircraft, a prismatic gunsight, but from 1944 a gyro gunsight was fitted which allowed more accurate deflection shooting.
Six underwing hardpoints allowed a combination of bombs up to I ,500rb. Trials with 827 Squadron in early 1943 to carry four 500lb. bombs was abandoned due to poor handling and 108S of performance. Instead a 1,600Ib. mine could be carried or the American 1,600lb armour-piercing bomb."

Sorry it took so long. Discus
 
How about a compromise?

Hi everybody! :wavey:

Sorry for getting back to this thread so late. It seems like all issues about the historical Barracuda armament are settled now.

Baldy, I had the idea of reducing the MkII anti-sub payload to your original 4 x Mk53 and then add an extra 6 x MkVIII (the Alpha weps) payload. How about it?

Cheers!
