/images/notams/notams22/vsky0920.jpgVSKYLABS 'Test-Pilot': F-19 Stealth Fighter for X-Plane 12 (X-Planeby Laminar Research) - A (very few) interesting facts, referring tothe attached split photo: Canopy:Interestingly, the original Testors F-19 model had a caged canopywith a center-line, similar to the one of the SR-71. However, theMicroProse F19 was equipped with a modern HUD, which was impossible tomount effectively in the caged canopy...The VSKYLABS F-19 v1.0 isequipped with the caged canopy, mainly because it was the authenticdesign and appearance of the aircraft, and one of the advantages isthat it boosts the flying challenge, especially the landings...tobecome the highlights in every flight, both in 2-d and VRenvironments. Intakes:In the original design, the intakes were covered to form aclose-shape with the fuselage. At the time, 'stealthy' was considered'round shape', 'no edges' etc...until the US declassified the F-117Aexistence...and blow all the assumptions to pieces (the F-117 wasnothing BUT sharp edges, corners and non-round shape). As part of the analysis of the 80's concept, it was obvious thatthe narrow slot around the intake covers provides too little airflowfor the engines, giving the fact that it is a jet fighter aircraft,intended for high AOA maneuvers. The 'chin' (the rounded shape aroundthe nose section, similar to the SR-71) provides some lift at highAOA...but it also induces vortexes that makes the air-intakes designeven more troublesome (probable compressor stall with every high-AOAmaneuver). So...the covers were completely removed in the VSKYLABSF-19 realization. In some non-Testors F-19 plastic models, the canards were shifteddown to the chin line. This can be a partial solution to manage highAOA chin induced vortexes and keeping it as far as possible from theintakes. Compressor stall vs AOA is implemented in the VSKYLABS F-19, toreplicate a plausible behavior in certain flying conditions thatinvolves slow speed/high AOA situations. AGM-65 Maverick:Visible in the lower split photo (two of these in a row, the secondis hidden). It was a highly 'popular' weapon in the MicroProse F-19simulation...however...it is not a perfect fit to be carried by astealth fighter aircraft, that was supposed to hit strategictargets. Its range is quite short (~17 miles), and its light warhead(~125 pounds) is aimed for tactical targets as tanks, and ships. TheVSKYLABS F-19 carries the AGM-158 low-observable cruise missile (seenin the other attached screenshot). With a range of ~230 miles and 1000pounds warhead, it could serve as a more 'fit' stealth fighterstandoff weapon. The included manual will cover a thorough analysis of the originalconcept, and of the VSKYLABS realization, in each and every aspect ofa proposed Jet-Fighter aircraft...should be an interesting read!

/images/notams/notams22/vsky0526/vskylabs-f19-1.jpgIn today's post, we will be focusing mostly on the F-19 engines: The original late 80's Testors F-19 Stealth Fighter conceptaircraft was deeply analyzed by VSKYLABS Aerospace Simulation experts,and was re-constructed bottom up, using the most advanced flightsimulation software up to date: X-Plane 12. Reminder: X-Plane is not a combat simulation. The VSKYLABS'Test-Pilot': F-19 Stealth Fighter project orientation is*Test-Flight* simulation of an experimental/concept jet fighteraircraft that allows to explore and challenge its design goals usingX-Plane 12 advanced flight simulation environment (aerodynamics,physics, weather, systems, handling and performance, mission-orientedtest flights and more!). /images/notams/notams22/vsky0526/vskylabs-f19-2.jpgGeneral aircraft specifications of the VSKYLABS F-19 are based onthe original 80's concept specs (which also existed in the 87'MicroProse F-19 Steath Fighter simulations). However, following thethorough analysis and test flights process during development, a fewmodifications/additional systems were added to the basic design,allowing a more probable mission-capable characteristics. One example for such modification is the F-19 engines: The originalF-19 concept aircraft was assumed to be powered by twonon-after-burning F404-GE-100 engines. The F404 engine first flight,btw, was in the 'new' U.S. Navy's F/A-18 fighter/attack aircraft inNovember 1978. In real-life, the F404-GE-100 derivative was flownextensively during the Northrop F-20 Tigershark program (1982 - 1986),delivered 11,000 pounds of thrust dry and 17,000 pounds usingafterburner, along with advanced digital electronic control andimproved reliability. The selection of twin NON-after-burning F404-GE-100 engines in theF-19 80's concept was based on the requirement of reducing the heatsignature of the stealth fighter. The airframe incorporated twosemi-hidden thermal-efficient exhaust nozzles, "hidden" by the largevertical fins, and equipped with an airflow cooling system. /images/notams/notams22/vsky0526/vskylabs-f19-3.jpgThe thorough mission-oriented test flights of the VSKYLABS F-19during development in X-Plane 12 lead to the decision of addingafter-burner capability, to improve its maximum weight take-offperformance, to allow a low-altitude deep penetration profiles withsupersonic capability, and to increase survivability in case ofdetection or interception by enemy fighters. Following this decision, the VSKYLABS F-19 two non-after burningF404-GE-100 engines were replaced by two after-burning GeneralElectric F414-GE-400 (these are powering the F/A-18E/F variants). The change of power-plant increased the dry thrust from ~11,000pounds to ~13,000 pounds. Maximum thrust however increased from~11,000 pounds to ~22,000 pounds...that is twice the power of thenon-after-burning F404-GE-100 engines. Fuel-consumption wise, the F-19 airframe capability of carryinginternal fuel is limited due to its size and shape, and using theafterburners extensively reduces its combat radius significantly. Forthis reason the use of afterburner power in the VSKYLABS F-19 isrestricted-by-system, and to enable after-burners operation duringflight - the pilot must "pass" through two guard switches (one foreach engine). Some complementary information regarding the attached WIPscreenshots: Weapons - Unlike the 87' MicroProse F-19, the VSKYLABS F-19 is notdesignated as a multi-role attack aircraft, and it can carry a verylimited weapons-suit: Two AIM-120 AMRAMM Air to Air missiles, carriedin two separate forward weapon bays, and a single AGM-158 JASSM(cruise missile) carried in the central belly weapon bay. The VSKYLABS F-19, like the F-117A Stealth Fighter, does not carryguns nor heat-seeking missiles for close-air combat/self defense. Theidea behind the weapons selection in the VSKYLABS F-19 was to adaptthe F-117A operational concept (no air-to-air capability, limited airto ground capability for pin-point targeting accuracy), and to fall inline with the plausible capability of carrying payloads in the F-19airframe (mass and volume). The two AIM-120 missiles are intended for intercepting enemy AWACSaircraft (with BVR capability), and the single AGM-158 low signaturecruise missile is intended for deep penetration, pin-point accuracytargeting. External fuel-tanks - Like the modern usage of non-stealthyexternal fuel tanks in stealth fighters (as seen in the F-35/F-22),the VSKYLABS F-19 is capable of carrying two external fuel tanks,extending its combat radius and allowing certain 'special mission'profiles. These are drop-tanks and can be dropped when needed (toreduce drag, to reduce radar signature, to increase maneuverability incase of 'trouble' etc...). The aircraft is also capable ofair-refueling. Landing gear - The F-19 is a carrier capable aircraft. Noticeable is the tail-hook and the carrier-capable landing gears which are designed following the NAVY carrier based F-18 aircraft landing gears. Using the F-18 landing gears design in the F-19 was part of the original late 80's concept (as well as the F-18 engines). Leading edge slats - Shown extracted in one of the screenshots. Theoriginal F-19 concept did not incorporate leading edge slats. Thesewere implemented into the VSKYLABS F-19 airframe as part of deeperexploration of high angle-of-attack performance and aircraftmaneuverability once the thrust to weight ratio exceeded more than 1:1with the use of after burners. A fascinating insight was with regardsto the small-span elevator flap - where the elevator flap, which ispositioned close and straight in line with the exhaust nozzles, actedas a thrust vectoring vane at high power settings. This configurationallows flying the F-19 at high angle of attack during certainmaneuvers, and the leading edge slats were implemented to explorethese flight envelope regimes. They are not required for takeoff orlanding. Cockpit screenshots - By concept, the VSKYLABS F-19 cockpit designand general systems are based on the F-18 aircraft, which shares a lotin common with the original F-19 80's concept. The VSKYLABS F-19 is afully featured aircraft simulation, includes all aircraft systems suchas pressurization, fuel, oxygen, electrical, pneumatic, hydraulics,engine management, avionics and so forth. Some of the systems aresimilar/identical to the ones to be found in the F-18 (electrical,pressurization, oxygen, hydraulics...), and some are unique, designedspecifically for the F-19 (fuel system, controls, avionics, andother). The result is a highly plausible aircraft design that is beingoperated as a conventional modern jet-fighter. Due to the unique flight model aspects and other simulation relatedaspects, the VSKYLABS 'Test-Pilot': F-19 Stealth Fighter project isbeing developed for X-Plane 12, and will be released exclusively forX-Plane 12. The project is in advanced development stages and is aimed to bereleased as soon as possible after upcoming X-Plane 12 will bereleased. Source

/images/notams/notams22/vsky0518.jpgComing soon for X-Plane by Laminar Research (developed exclusively for upcoming X-Plane 12). The VSKYLABS 'Test-Pilot': F-19 project is a fusion of *fiction*and *science*...where the main development goal was to create a deep,plausible, scientifically-based aircraft. NOT a science-fiction /"arcade" aircraft with the visuals of the F-19 "skin"... During the in-depth process of bringing the fictional (yetplausible) 80's concept of the F-19 Stealth Fighter to life, VSKYLABSdecided to derive some of the F-19 aircraft systems and cockpitarchitectures from a real-world, advanced jet-fighter: The F-18. As aresult, some aircraft architecture and cockpit design features weremodeled and engineered based on references of the real-world, advancedjet-fighter design, contributing to the depth and "plausibility" ofthe F-19 design and aircraft operations aspects. The F-19 80's concept and the F-18 are similar in many ways; Bothaircraft are twin-engine, all-weather, fighter/attack aircraft withcarrier-operations capability. The 80's F-19 stealth fighter conceptaircraft was powered by two F404-GE engines variants, of the samepower-plant family of the F-18. Obviously the systems are not 100% identical as the F-18 and F-19are not sharing the exact same systems and fighting roles. Forexample, the F-19 fuel system is different than the one on-board theF-18 (including the air-refuel system). Other differences exist due tothe fact that the F-19 consists of a whole different airframe andcontrols layout, and it does not carry some of the F-18 equipment andweapons. On the other hand, the landing gears, hydraulics, ejectionseat, oxygen and pressurization systems, engine controls, electricalsystems and part of the weapon systems are almost identical byconcept. The VSKYLABS F-19 cockpit was modeled with the unique systems andfeatures of the F-19, but with the general approach and designfeatures of the F-18 cockpit environment. At first sight, the cockpitmay look quite familiar for the F-18 pilots. However, when digging in,it is not identical and some things/systems are done/operated andmonitored quite differently. Avionics and weapon systems: X-Plane is not a combat flightsimulator, and the main orientation of the project is of an advanced'Test-Plane', trying to challenge the 80's concept in the fascinatingworld of X-Plane. One example is the service ceiling of the proposed80's concept...being 60,000 feet. Is this feasible with the givenairframe, powerplant, designed combat airspeed and fuel/payloadon-board? Other example is carrier ops - takeoff and landing speeds,AOA and other considerations. Challenging the concept goes reallyfascinating when testing the proposed flight controls layout in"combat-like" situations and in dead-stick landings. There are manymore aspects that are being challenged in the most scientificallyapproach, thanks to X-Plane 12. To add that by concept, the projectwill include a thorough manual booklet that is breaking down the F-19concept, bit by bit, demonstrating and explaining its design featuresand consequences in-flight (in X-Plane 12). The late 80's MicroProse F-19 game/simulator (1987) was equippedwith 4 separate weapon bays and was able to carry a huge variety ofpayloads: Air to Air heat-seeking missiles, Active radar missiles,Anti-radar missiles, Laser-guided bombs, Cluster bombs and more. The VSKYLABS 'Test-Pilot': F-19 has (only) 3 separate weapon bays,designed to carry (only) total of 2 BVR active radar Air-to-Air guidedmissiles plus a single Low-observable (stealthy) standoff air-launchedcruise missile. These are modeled into the project, extending its'Test-Pilot' experience (such as experimenting with the releaseenvelope of a cruise missile...you cannot just launch themini-aircraft...without paying attention to flying speed, g-load, AOAand so forth...). Similar to the F-117A, the VSKYLABS F-19 does notcarry guns or additional "self-defense" Air-to-Air missiles. The decision of this weapons selection was a result of two generalconsiderations: a) The proposed mission of the stealth fighters totarget AWACS aircraft, and b) The proposed mission of the stealthfighters to launch stealthy attacks, deep inside enemy territory,using stealthy weapons. Additional information and screenshots will be shared once"DECLASSIFIED"... Source

/images/notams/notams20/vsky1023.jpgMeanwhile at VSKYLABS...Last preparations before taking off toanother exciting test flight in the (Work In Progress) VSKYLABS F-19Stealth Fighter (X-Plane 11). The 2015 project, which was initiallydeveloped for X-Plane 10, is being heavily re-designed and re-modeledso that it will fall in line with the latest VSKYLABS developmentstandards, and with the latest X-Plane 11 features sets. At the time, the F-19 was a fictional aircraft which was based onspecialists and experts insights and estimations. A few years after itwas introduced as a plastic kit-model and in the classic 80's 'F-19Stealth Fighter' flight simulator game, the real stealth fighter, theF-117A was exposed to the public eye, and it was found that theenvisioned F-19 concept was quite close to the *real thing*. The VSKYLABS F-19 project is a fascinating scientific journey intothe plausibility aspects of the aircraft, and although it represents afictional concept, several real world fighter pilots are deeplyinvolved in the making of it, bringing the most authentic andplausible characteristics to life, in X-Plane.
