KC-135 Boom Operator Panel

Boom operator’s panel

Here is a picture of the boom operator’s panel of the KC-135 stratotanker.

• The gauges at the top indicate the position of the air refueling boom. The green arcs represent the air refueling envelope that the receiver aircraft must remain inside of. The red markings on the gauges are the limits of the air refueling envelope. If the receiver exceeds these limits and the tanker’s signal system is in NORMAL, then an automatic disconnect will occur.
• The boom signal coil voltmeter on the right of the panel shows the status of the boom nozzle signal coil when the PUSH TO TEST button is pressed. The voltmeter displays OPEN, GOOD, and SHORTED.
• The TEST CONTACT button advances the signal system to CONTACT when pressed if the signal amplifier is operational.
• The RESET READY button resets the signal system to READY.
• The blue, green, and orange lights display the current status of the air refueling signal system. The blue READY light indicates the system is ready for contact with a receiver. The green CONTACT light indicates that the boom is in contact with a receiver and that fuel transfer can occur. The orange DISCONNECT light indicates that a disconnect signal has been received.
• The TLSCP AT DISCONNECT (telescope at disconnect) switch selects if the boom will automatically retract when a disconnect signal is received. It has two positions AUTO, and MANUAL.
• The PILOT DIRECTOR LIGHTS are controlled by four rheostats for the background elevation & letters and telescope and for the position elevation and telescope pilot director lights.
• The NACELLE ILLUMINATION rheostats control the brightness of the engine illumination lights.
• The A/R FlOODLIGHT rheostat controls the brightness of the tail mounted air refueling floodlight.
• The BOOM NOZZLE rheostat controls the brightness of the boom mounted nozzle light that shines light on the boom nozzle.
• The UNDER BODY rheostat controls the brightness of lights mounted on the inboard side of the inboard engine struts that illuminate the under body of the aircraft to help with night air refueling.
• The UNDER WING rheostat controls the brightness of lights mounted on the underside of the aft fuselage that illuminage the underside of the wings.
• The BOOM MARKER controls turn on ultraviolet fluorescent tube lights mounted in the boom that cause fluorescent markings on the boom to glow for night air refueling. The ON/OFF switch controls power to the lights and the START positions of the start switch each turn on one of the two fluorescent lights. The neon lights indicate the status of the marker lights.
• The DIRECTOR LIGHTS GROUND TEST switch is used to turn on all pilot director lights at once for maintenance testing.

A Convair UC-880 aircraft, the only such aircraft in U.S. Navy service, refuels an F/A-18A Hornet aircraft. The Convair is assigned to Naval Air Test Center, Patuxent River, and is employed in Tomahawk cruise missile testing and refueling aircraft procedures.

The United States Navy purchased one 880 which was modified as an in-flight tanker. Unofficially designated UC-880, it was assigned to the Naval Air Test Center, Patuxent River, and employed in Tomahawk cruise missile testing and aircraft refueling procedures. The UC-880 was destroyed in a cargo hold explosion test at NAS Patuxent River, Maryland in 1995.

Northrop YF-23 – In-Flight Refueling

Design and development

The YF-22 and YF-23 were competing in the USAF’s Advanced Tactical Fighter (ATF) program, conceived in the early 1980s, to provide a replacement for the F-15 Eagle. Contracts for the two most promising designs were awarded in 1986.

The YF-23 was designed to meet USAF requirements for survivability, supersonic cruise (supercruise), stealth, and ease of maintenance. Designed with all-aspect stealth as a high priority, Northrop drew on the company’s experience with the B-2 Spirit and F/A-18 Hornet. The YF-23 was an unconventional-looking aircraft with trapezoidal wings, substantial area-ruling, and a V-tail. It introduced the novel feature of rear jet nozzle troughs lined with heat ablating tiles developed by Allison, which shielded the exhaust from infrared (IR) detection from below. All the control surfaces were coupled together via the Vehicle Management System to provide “net effect” aerodynamic control. The wing flaps and ailerons deflected inversely on either side to provide yaw, while the tail provided pitch. Aerodynamic braking was achieved by deflecting the flaps and ailerons on both sides simultaneously.

Although possessing an advanced design, in order to reduce costs and development, a number of F-15 Eagle components were utilized including the standard F-15 nose wheel unit and the forward cockpit of the F-15E Strike Eagle. Two aircraft were built. YF-23 #1 (PAV-1) was fitted with Pratt & Whitney YF119 engines, while YF-23 #2 (PAV-2) was fitted with General Electric YF120 engines. The YF-23 featured fixed nozzles. The first YF-23 was rolled out on 22 June 1990, and first flew on 27 August 1990. YF-23 #2 first flew on 26 October 1990.

The black YF-23 (PAV-1) was nicknamed “Black Widow II”, after the Northrop P-61 Black Widow of World War II and had a red hourglass marking resembling the underbelly marking of the black widow spider. The black widow marking was briefly seen under PAV-1 before being removed at the insistence of Northrop management. The gray colored YF-23 (PAV-2) was nicknamed “Gray Ghost”.

Operational history

Evaluation

Both YF-23s were furnished in the configuration specified before the requirement for thrust reversing was dropped. The weapons bay was configured for weapons launch but no missiles were fired, unlike Lockheed’s demonstration aircraft. The YF-23s flew 50 times for a total of 65.2 hours. The YF-22 achieved Mach 1.58 in supercruise. The first YF-23 with P&W engines supercruised at Mach 1.43 on 18 September 1990 and the second YF-23 with GE engines reached Mach 1.6 on 29 November 1990. The flight testing demonstrated Northrop’s predicted performance values for the YF-23.

The YF-22 won the competition in April 1991. The YF-23 design was more stealthy and faster, but the YF-22 was more agile. It has been speculated in the aviation press that the YF-22 was also seen as more adaptable to the Navy’s Navalized Advanced Tactical Fighter (NATF), though as it turned out the US Navy abandoned NATF a few months later.

After losing the competition, both YF-23 prototypes were transferred from Northrop to NASA’s Dryden Flight Research Center, at Edwards AFB, California. The engines were removed. NASA had no plans to perform flight tests with the airframes, but a proposal was put forward to use one of the two aircraft to study strain gauge loads calibration techniques. The possible production configuration of the F-23A has never been publicly revealed.

This unique concept is the product of the vast Sargent Fletcher experience in External Fuel Tank and Probe/Drogue Aerial Refueling systems design. The Sargent Fletcher 370-Gallon wing tank is modified to accept a retractable probe that will permit a F-16 aircraft to receive fuel from a Probe/Drogue-equipped tanker. A proof of concept flight test was conducted to verify the compatibility of the design to the hoop-up loads. No fuel was transferred in this test. Instrumentation was installed to measure loads, deflection, and stiffness. The test confirmed the loads placed on the probe and the ease of hook-up including the compatibility of the system to several different tankers.

VISTA with ARTSA later test was conducted with the ART/S® installed on the specially configured F-16 Variable Stability In-flight Simulator Test Aircraft (VISTA). The VISTA test flights confirmed that the ART/S® was compatible with various aircraft computer programs. When a F-16, and many other aircraft in the USAF inventory, is equipped with an ART/S®, it can receive fuel, not only from the boom/receptacle tankers, but also from any tanker in the worldwide fleet.

The Lockheed Martin F-16 VISTA (“Variable stability In-flight Simulator Test Aircraft”) program, which ran from 1988 to 1997, began as a privately funded joint venture between General Electric and General Dynamics, to produce a Multi-Axis Thrust-Vectoring (MATV) variant of the Fighting Falcon.

The F-16 VISTA testbed aircraft incorporated a multi-axis thrust vectoring (MATV) engine nozzle that provides for more active control of the aircraft in a post-stall situation. The resulting aircraft is supermaneuverable, retaining pitch and yaw control at angles of attack beyond which the traditional control surfaces cannot change attitude.

The VISTA program was considered successful, but the thrust vector control (TVC) never made it into production fighter versions.

The program was also notable for the development of Direct Voice Input and the “Virtual HUD”, which were both eventually to be incorporated into the cockpit design for the F-35 Lightning II. The STOVL F-35 variants also incorporate MATV while hovering to provide attitude control.
