Your best bet on that would the MAT books: http://www.macrossworld.com/macross/books/dou_mat3extra.htm but they are rare and in Japanese, other then that I would guess take the figures on the F-14 and up 'em by 25%, as a rough guess, but there is no real way to get official numbers on that.

Does anyone have this "MAT Book" and could give me new information that I could not find elsewhere on the net?

Very good job bro hope it workout, I hope you make one for the MS flight sim also.

I don't know anything about MS flight sim. Maybe there is a way to port X-Plane aircraft over. I know of converters that will import MSFS scenery over to X-Plane. Hopefully, it's something someone else can do in the future.

However, I think you would loose most of the fidelity if you model in MSFS. That's just what I heard.

Well, people are launching Millennium Falcons and Serenities (and a Battlestar, dammit!) out there at X-Plane.org, and talking about importing Lightwave models wrapped around Planemaker models and such nonsense, so I guess you can attach a visual model over a physics model. I guess that's kinda cheating (from an engineering point of view anyway), but, hey, people like their eye candy.

Yep. The physics is what I am concerned with the most, but I guess it's something that someone else can attempt down the road.

Hmm. Maybe I should get a copy of 8.0 and try and model a Viper Mk VII.

However, Austin Meyer really, really, should get to overhaul Planemaker. IMHO, that thing is only good for modeling airliners - I pity whoever try to make a YF-23 or F-117 in it.

There is a pretty good YF-23 floating around on the X-Plane.org downloader.

I used some of its control logic--Ralph Pelican V-Tail configuration--for my own rendition of a VF-4 production aerocraft based on the VF-4-X. I love that Pelican Tail; from my experience, it's weak in yaw, but it's killer in pitch.

BTW, is there any information out there about the Valkyrie's flight characteristics--such as it's variable geometry wings especially--out there besides what is in the Macross compendium? I am trying to nail down spoiler and aileron cut out speeds as the aerocraft transitions to supersonic flight and near full wing sweep. Any information would help.

If anyone has some comments or suggestions, feel free to chime in. I am wrapping this up soon.

I think these are pretty close.

There are some things like wing dihedral and twist that I will not change.

It is even possible for something not made in the X-Plane modeler to work in X-Plane? Last time I checked, it was necessary so the airflow simulation engine could run the simulations. Then again, I haven't touched X-Plane since version 5.0

Yes, I believe that is accurate.

Yeah, those could be used as great reference source for your project.

Thanks.

I'll post some corrections soon.

Sorry to rain on your parade mate, but the proportions DO look off. Nice modding nonetheless.

I don't take constructive criticism personally.

Where are the proportions off?

Does anyone have a picture of a model of a Hornet and a Valkyrie for a basis of comparison?

That's your opinion.

Macross.anime.net

X-Plane 8.60

looks like you squished it in that picture.

It's according to scale. (The featured fighter on the left is a F-22A; the one on the right is a F/A-18E.)

Sub fifty foot fighters often look "squished," at least to me.

Maybe, it's the angle.

This is my first post, and I wanted to let anyone know who is interested that I am almost finished with the Valkyrie.

The flight test team and I have a few issues yet to work out with the flight control logic along with carrier suitability.

I used Macross source material to construct a rendition of the Valkyrie. I used the elements that worked, removed those that didn't, and made alterations for the sim's capabilities. Overall, I am satisfied with the design, and I hope everyone else is too. The paint scheme is reminiscent of what is seen on the X-35C demonstrator with a few tweaks here and there.

I am sorry that this is Robotech Valkyrie, but it is still a Valkyrie.

No one is perfect I guess. Here is the technical data on the flight model. I am sorry for the length.

VF-1A-35 Test Data

All measurements are approximate figures.

Tests were performed with GU-11 on centerline at 34,651 lbs (airport 26 C, 30.04 in Hg).

Class: 1st Generation Veritech/Variable Carrierborne Variable Geometry Aerospace Multi-Role Fighter

Service: RDFN (UNN), RDFS (UNS), RDFM, RDFAF (UNSAF), TASC, TAF, EFS, EFAF, EFM

Height (on gear): 14.68 ft. (-0.95 deg)

Length: 47.5 ft.

Wingspan (unswept, 20deg): 48.76 ft.

Wingspan (swept, 60deg): 32.28 ft.

Aspect ratio (unswept): ~5.33

Aspect ratio (swept): ~<2.00

Cruise L/D (35,000 ft, 0.80 Mach): 5.8:1

Max Cruise L/D--VG override (35,000 ft, 0.80Mach): 7.6:1

(L/D is a mark of subsonic aerodynamic efficiency.)

Weight (empty): 29,000 lbs

Weight (combat, typical): 35,700 lbs [12 AMM-1 Stilletos, 1 GU-11]

Weight (maximum): 45,000 lbs

Weight (typical D20, 50% fuel): 300 lbs [enough to maintain limited LEO, SFC .01 lbs/hr]

Engines (atmosphere): 104,000 lbs [overboost, 200%], 52,000lbs [military, 100%]

Engines (space): 104,000 lbs

TtW (military, atmosphere, typical combat weight): 1.46: 1

TtW (military, atmosphere, GU-11 on centerline): 1.60: 1

Max Speed (1,000 ft. AGL, overboost): Mach 1.35

Max Speed (10,000 ft. AGL, overboost): Mach 1.88

Max Speed (30,000 ft. AGL, overboost): Mach 2.50+

Max Speed (60,000 ft. AGL, overboost): Mach 4.50+

Speed (1,000 ft. AGL, military): Mach 1.00

Speed (10,000 ft. AGL, military): Mach 1.10

Speed (30,000 ft. AGL, military): Mach 1.88

Supercruise (40,000 ft. AGL, military): Mach 1.90+

Maximum Service Ceiling: > 400,000 ft.

Take Off Speed (military): 120 knots

Vunstick: 135 knots

Carrier Landing Approach: 135 knots, 8 deg AOA

Stall Speed (generalized): 100 knots, 18.5 deg AOA

Time to Atmospheric Ceiling (takeoff to 120,000 ft, overboost, not in reaction mass mode): 99 s

Climb Rate (during atmospheric ceiling climb): 72,727ft/min+

Note: Climb rate during atmospheric ceiling is less actually than climb rate in atmosphere due to the engine's power loss in thinner air and the vacuum.

Models -J and -S with an additional 6,000 lbs thrust combined in military and 12,000 lbs in overboost should have a better than marginal climb rate when compared to the -A.

The following is representative of the final performance of the airframe with full consideration of a humanoid operator.

FBW Instantaneous G-Load (350knots, 10,000 ft. AGL): 8.5 G

FBW Maximum Roll-Rate (350knots, 10,000 ft. AGL): 310 deg/sec

FBW Maximum Roll-Rate (550knots, 10,000 ft. AGL): 170 deg/sec

FBW Best Instantaneous Turn Rate 180 deg turn (500 KIAS, 1,000 ft AGL, military): max 9.5 G, ~27 deg/s (stall)

FBW Best Sustained Turn-Rate 360 deg turn (400 KIAS, 1,000 ft AGL, military): 9.5 G, ~20 deg/s

FBW Best Instantaneous Turn Rate 180 deg turn (400 KIAS, 10,000 ft AGL, military): max 9.0 G, ~25 deg/s (stall)

FBW Best Sustained Turn-Rate 360 deg turn (400 KIAS, 10,000 ft AGL, military): 8.0 G, ~19 deg/s

FBW Best Instantaneous Turn Rate 180 deg turn (400 KIAS, 30,000 ft AGL, military): max 9.0 G, ~16.5 deg/s (stall)

FBW Best Sustained Turn-Rate 360 deg turn (400 KIAS, 30,000 ft AGL, military): 5.5 G, ~11 deg/s

Models -J and -S with an additional 6,000 lbs thrust combined in military would potentially have better performance throughout the entire flight envelope but especially at higher altitudes.

Maximum Controllable AOA: +55deg/-30deg

Structural G-Limit: +11.5 G/-5.5 G

FBW G-Limit: +10.5 G/-4.5 G

Flying Controls: Valkyrie has a redundant fly by light control system. The main wing is a two section fowler flap (flaperons out board, flapervators in board) with spoiler/speedbrake that occupies the entire trailing edge with full leading edge slats. Midbody LERX has wing fence and conventional outward canted vertical stabilizers with center mounted rudder. Two-dimensional thrust vectoring (20 deg pitch, 10 deg roll) replace conventional tailerions. Assorted vernier thrusters assist in pitch control in atmosphere, and three dimensional thrusters provide attitude control in a vacuum. One pair of small ventral mounted strake elevators to assist in correcting pitching moments, and there is a speedbrake stored behind the fuselage's cockpit.
