The DMS is a high-fidelity model of the ACES II aircraft ejection seat as installed in the F-15 aircraft and includes all of the motors, actuators, linkages, handles, and adjustment mechanisms required to provide motion cueing throughout the aircraft flight envelope.
ACME’s F-15 ACESII dynamic motion seats are a combination of vehicle crew seats with electric motion components built inside the seat. The seats look, feel, and function like actual crew seats, and provide cues to emulate sensations felt during the vehicle or in-flight operations.
ACME seats translate simulator acceleration signals into realistic, convincing motion. True Q® seats provide a higher level of cueing, where the motion IS training, for example feeling unique signature sensations such as translation lift between Helicopters vertical and horizontal flight or the difference between a helicopter rotor out of balance or a blade of track.
The seats use a patented electric system with individual motion plates/pans, providing cues directly to the crew’s body. It’s the effect of multiple channels in the seat working seamlessly together that provides complete, realistic, immersive cueing.
The COTS core motion system inside is adaptable to any external seat shape or form so we can provide motion seats for nearly any Military & Commercial simulator.
In fact, we’ve produced dynamic motion seats for training systems worldwide including land vehicles such as locomotives, and Humvee-trucks, helicopters including AH-64, Multiple H-60 models, NH90, CV-22s, and fighter jets including like M346, F-15, F-16, & T-50. We can pair fighter seats with our G-suit system too for additional cueing capability.
ACME’s True Q® motion seats are an ideal way to cost-effectively add realistic motion cueing to any Sim. Motion Seats are much less expensive that motion platforms and offer much greater cueing than seat or platform shakers and ACME seats can provide unique cues such as yaw twist simply not available in platforms or shakers.
The McDonnell Douglas (now Boeing) F-15 Eagle is an American twin-engine, all-weather tactical fighter designed by McDonnell Douglas to gain and maintain air superiority in aerial combat. It is among the most successful modern fighters, with over 100 aerial combat victories. Following reviews of proposals, the United States Air Force selected McDonnell Douglas’ design in 1967 to meet the service’s need for a dedicated air superiority fighter. The Eagle first flew in July 1972, and entered service in 1976.
The Eagle has since been exported to Israel, Japan, and Saudi Arabia, among other nations. The F-15 was originally envisioned as a pure air superiority aircraft. Its design included a secondary ground-attack capability that was largely unused. The design proved flexible enough that an all-weather strike derivative, the F-15E Strike Eagle, was later developed, entering service in 1989. The F-15 Eagle is expected to be in service with the U.S. Air Force past 2025. Newer models are still being produced for foreign users. The F-15 production line is set to end in 2019, 47 years after the type’s first flight.
The F-15 uses a ACES II ejection seat system manufactured by the United Technologies Aerospace Systems (UTAS) division of the United Technologies Corporation (UTC). ACES is an acronym for Advanced Concept Ejection Seat. It is used in Fairchild Republic A-10 Thunderbolt II, McDonnell Douglas F-15 Eagle, General Dynamics F-16 Fighting Falcon,Lockheed Martin F-22 Raptor, Lockheed F-117 Nighthawk, Rockwell B-1 Lancer, WB-57, and Northrop Grumman B-2 Spirit aircraft. Over 10,000 ACES II seats have been produced with over 5,000 actively flying throughout the world as of 2013. It is known throughout the industry as the lowest life cycle cost third generation seat due to theUSAF owning the rights to the seat, facilitating competitive replacement part procurement. In addition, the buying power of 5,000 in-service seats and previous service life extension programs have further driven down support costs.
The seat is considered third generation and includes advanced features. For example, it senses the conditions of the ejection (airspeed and altitude) and selects the appropriate drogue and main parachute deployments to minimize the forces on the occupant. The seat is controlled by a fully redundant digital electronic sequencer which makes the decisions and initiates the appropriate seat components to allow the seat to fly through the air and safely descend the aircrew to the ground. The sequencer includes a crash data recorder that contains ejection information that can be later analyzed during crash investigations to understand the dynamics of the ejection as well as loads on the aircrew during the event. The seat propulsion system is specially designed with technology to compensate for aircrew weight so that the 103 lb small female aircrew gets a similar acceleration to the 245 lb male pilot. The seat has been updated over the years through pre-planned product improvement programs to include digital sequencing, additional redundancy, enhance stability, limb restraints, structural upgrading, and passive head/neck restraints. The ACES II seat ejection injury rate is one of the lowest in the world as proven in over 600 live ejections. Back injury rates occur in only 1% of ACES ejections compared to 20% to 40% in most other ejection seats.
The A-10, F-15, F-117, B-1, and B-2 use connected firing handles that activate both the canopy jettison systems, and the seat ejection. Both handles accomplish the same task, so pulling either one suffices. The F-22, WB-57, and F-16 have only one handle located between the pilot’s legs, due to cockpit space limitations.
The minimal ejection altitude for ACES II seat in inverted flight is about 140 feet (43 m) above ground level at 150 KIAS. The seat performance is in accordance with MIL-S-9479 as tailored for each aircraft application. Excellent terrain clearance performance under 250 KEAS is achieved by deploying the main parachute immediately after exiting the cockpit. It is the only ejection seat that can deploy the main parachute this early in the ejection sequence.
The ACES seat was originally developed and produced in Long Beach, CA by McDonnell Douglas. Weber Aircraft company also produced the seat as part of a USAF mandated “leader/follower” program. In the late 1980s the McDonnell Douglas production line was relocated from Long Beach, CA to Titusville, FL. The Weber Aircraft ACES production line eventually closed as USAF needs for ejection seats declined. In the late 1990s, Boeing and McDonnell Douglas merged with the combined company retaining the Boeing name. In 1999, Goodrich acquired the ACES product line from Boeing and eventually relocated the production line to Colorado Springs to the Aircraft Manufactures Inc. (AMI) facility owned by Goodrich. In 2012, United Technologies acquired the Goodrich Corporation. Today the ACES seat product line continues to be manufactured in Colorado Springs, Colorado.
ACME Worldwide Enterprises Dynamic Motion Seats are in the 5th Generation of evolution. The product line is robust and well-tested to be used in a high-intensity training environment. ACME offers a military grade solution for delivering patented motion cueing to any F-15 Simulator or Part Task Trainer.
ACME’s F-15 ACESII dynamic motion seats also have the tactile/visual details like: the ejection/arming/oxygen levers with I/O, the switches for transponders and survival kit deployment, the headbox, harnesses, pitot probes, cushions, and also replicates the 17 degree declination of the aircraft seat.
