MY BACKGROUND Currently Director, ASME Managing Director, Knowledge & Community Started out as an ASME understudy part - simply like you. A part for a long time. BS Temple University, Philadelphia MA, CSUN, Northridge, CA Staff of Congressman Jon Fox (PA/13) Northrop Grumman – Lead Engineer T-38 Talon • F-5E/F Tiger II • F-20 Tigershark • YF-23 Advanced Tactical Fighter, F/A-18E/F Super Hornet Rockwell Space Systems Division (Boeing) Space Shuttle Program NASA Kennedy Space Center Summer Intern - Space Shuttle Launch Facility Design

MODERN FIGHTER AIRCRAFT REQUIREMENTS Air Superiority – controlling the airspace inside a constrained region and inside a restricted time allotment Stealth – seeing the foe before they see you Maneuverability – not beat speed, but rather climbing execution, quickening and turning speed Aerodynamics – wing stacking – flying machine weight partitioned by wing region – a standout amongst the most vital Range – capacity of the flying machine to achieve the battle zone and cover it Engine – push to weight proportion, good fuel utilization, low infrared and smoke Avionics – Vehicle and frameworks administration, lessened pilot workload, all climate ability Armament - kind and amount of stores on load up Reliability and Maintainability – frameworks have a high operational rate and are anything but difficult to repair

Slide 5

THE EVOLUTION OF STEALTH AIRCRAFT From the soonest days, misleading and stealth have been utilized to pick up the favorable position over a foe in battle. Early battle air ship utilized cover to make visual recognition troublesome. The appearance of RADAR in the late 1930\'s and amid WWII empowered the early discovery of flying machine in flight. Romulan "Fowl of Prey" Equipped with "Shrouding Device." Made the art imperceptible to Federation sensors.

Slide 6

THE EVOLUTION OF STEALTH NORTHROP YB-49 BOMBER Designed by Jack Northrop in the late 1940\'s. Part was as a vital plane. Its remarkable wing shape delivered a low radar cross area, in spite of the fact that the objective was enhanced execution.

Slide 7

THE EVOLUTION OF STEALTH DESIGN IN THE 50\'S AND 60\'S Stealth in air ship outline does not mean undetectable – it signifies "Low Observable," diminishing the radar cross segment. Little exertion in the 50\'s and 60\'s. Coordinating low discernible viewpoints implied trading off execution – so originators focused on velocity, mobility, and weapons. A-12/SR-71 has adjusted lines, wing/body mixing, funnel shaped focus bodies, fuselage chine and inclined twin blades to diminish radar reflectivity. Lockheed SR-71 Blackbird

STEALTH CHARACTERISTICS Airframe formed for Low Radar Cross Section Use of Radar Absorbent Material (RAM) Minimized motor commotion Reduced infrared mark Reduced visual mark Use of electronic countermeasures

THE FIRST STEALTH AIRCRAFT F-117A Nighthawk USAF and DARPA considers started in 1973 – venture Have Blue Air Force welcomes recommendations to create innovation model Lockheed and Northrop were finalists and each manufactured a model for a "take off" Lockheed wins creation contract in 1976 Mission – secret observation and incognito surgical strikes Subsonic – restricted execution

FIGHTER GENERATIONS Gen 1 – Earliest stream warriors: Germany\'s Me 262, Britain\'s Meteor, US F-80. Trademark was advance in rate over cylinder motor air ship Gen 2 – Korean War period: USAF f-86 and Soviet MiG-15. Originators augmented execution by customizing airframe to stream motor. (Utilization of cleared wings is an illustration) Gen 3 – late 50s mid 60s: USAF Century Series F-100, F-101, F-102, F-104, F-105, F-106 and Soviet MiG-17 and MiG-21. Included propelled rockets, supersonic speed and advanced motors. F-4 Phantom was late Gen 3 warrior. Gen 4 – mid 1970s: USAF F-15 and F-16 and Soviet Su-27 and MiG-29. Exceptionally flexibility, refined weapons, motors and aeronautics. Gen 5 – today: all angle stealth, interior weapons, attachment and play gadgets and supercruise. USAF F-22 and F-35 coming.

STEALTH GROWS UP 1980 report inferred that B-1 plane would be not able enter Soviet air space past 1990 Positive results from Have Blue (F-117) supported dispatch of a full-scale low-detectable aircraft program (Advanced Technology Bomber – ATB) Lockheed/Rockwell group and a Northrop/Boeing group reacted to demands for proposition Northrop depended on experience concentrating on stealth innovation and its broad involvement with flying wing outlines and was granted the agreement

STEALTH GROWS UP NORTHROP – GRUMMAN B-2 SPIRIT Length – 69ft Height – 17ft Wingspan – 172 ft Max Speed – Mach .85 Range 6300 nm Armament – 40,000 lbs in inner weapons coves Powerplant – four GE F-118-GE-100 turbofans – 17,300 lbs

Slide 13

DEVELOPING A TRULY STEALTH FIGHTER WHY THE NEED? Late 1970\'s – Soviets working much a bigger number of contenders than US Massive Soviet surface to air rocket danger USAF looking to innovation to counter Soviet numerical point of interest In 1981 USAF issued a Request for Information (RFI) for the Advanced Tactical Fighter (ATF) A RFI does not offer any cash or generation contracts, it characterizes mission, the risk, administration passage date and new elements that are alluring and attainable Supercruise (the capacity to accomplish supersonic flight without max engine thrust) and stealth were viewed as fundamental parts, in spite of the fact that stealth was still viewed as an extraordinary innovation

Slide 14

DEVELOPING A TRULY STEALTH FIGHTER THE ADVANCED TACTICAL FIGHTER (ATF) PROGRAM Air Force selects to fabricate a really aerial warrior to take after the F-15 Eagle air predominance contender - intended to enter administration in mid 90\'s In 1983 USAF issues Request for Proposals (RFP) for ATF and the Joint Advanced Fighter Engine (JAFE) General Electric and Pratt & Whitney compete for motor contract Lockheed, Rockwell, Grumman, McDonnell Douglas, General Dynamics, Boeing and Northrop strive for flying machine contract McDonnell Douglas and General Dynamics were thought to have within track as a result of F-15 and F-16 But stealth ended up being the central component. Both Northrop and Lockheed fell back on their stealth encounter and proposed stealthy contenders that could execute and in addition non-stealthy warriors

Slide 15

DEVELOPING A TRULY STEALTH FIGHTER THE ADVANCED TACTICAL FIGHTER (ATF) PROGRAM In October 1986 the USAF honors the agreements to manufacture model air ship to Northrop and Lockheed Northrop cooperated with McDonnell Douglas to construct the YF-23A Lockheed - Boeing - General Dynamics involved the other group to assemble the YF-22A. Air ship first flights in the Fall of 1990. Lockheed Martin honored contract in April 1991. The F-22 is currently underway.

AIRCRAFT DESIGN IS A COMPROMISE It is the assignment of the air ship plan specialist to adjust the client necessities with the physical limitations, cost and time-scale, keeping in mind the end goal to deliver the best flying machine conceivable. Air ship Design Requires Teamwork No "one" configuration gathering is more imperative than the others. Note: All Engineering includes Compromises!
