Description Spike Aerospace is seeking experienced powerplant engineers with knowledge of turbine engines and engine integration. Three XRS-2200 engines were built during the X-33 program and underwent testing at NASA's Stennis Space Center. It will have a cruising speed of mach1.6 (1,100mph) and a stall speed of 105kt. Exhaust recirculation in the base zone of the spike can raise the pressure in that zone to nearly ambient. CSULB students had developed their Prospector 2 (P-2) rocket using a 1,000 lbf (4.4 kN) LOX/ethanol aerospike engine. Both are working on smaller demonstrator aircraft with different engines designed to … The first thing you’ll notice upon entering the cabin of the S-512 are the expansive, high-definition screens spanning each side. Designed for corporate and investment executives, the … Flying at Mach 1.6, it is 450 mph faster than any other civilian aircraft which enables Spike S-512 travelers to do more and enjoy more of life. Spike S-512 engine and performance Spike Aerospace has not yet finalised the engines to be used by the S-512. The recirculation zone at the base of the spike maintains the pressure in that zone to a fraction of 1 bar, higher than the near-vacuum in front of the vehicle, thus giving extra thrust as altitude increases. Spike Aerospace is looking for low to medium by-pass ratio (BPR) engines with approximately 20,000 lb sea-level thrust. This rocket design was never launched. In theory this requires an infinitely long spike for best efficiency, but by blowing a small amount of gas out of the center of a shorter truncated spike (like base bleed in an artillery shell), something similar can be achieved.  It belongs to the class of altitude compensating nozzle engines. Lockheed Martin chose to not continue the VentureStar program without any funding support from NASA. Thirty years later their work was revived for use in NASA's X-33 project. An aerospike rocket engine seeks to eliminate this loss of efficiency. Later models of these engines were based on their highly reliable J-2 engine machinery and provided the same sort of thrust levels as the conventional engines they were based on; 200,000 lbf (890 kN) in the J-2T-200k, and 250,000 lbf (1.1 MN) in the J-2T-250k (the T refers to the toroidal combustion chamber). For example, a milestone was achieved when a joint academic/industry team from California State University, Long Beach (CSULB) and Garvey Spacecraft Corporation successfully conducted a flight test of a liquid-propellant powered aerospike engine in the Mojave Desert on September 20, 2003.

Spike S-512 Engine Spike Aerospace has not completed the machine that will be used by the S-512. In this case the slightly upgraded J-2S engine machinery was used with a linear spike, creating the XRS-2200. Spike CEO Vik Kachoria said his company was in talks with two engine suppliers. This supersonic business jet is meant to sail at high speed Mach 1.6, allowing passengers to succeed in their destination … Furthermore, the larger cooled area can reduce performance below theoretical levels by reducing the pressure against the nozzle. , The idea behind the aerospike design is that at low altitude the ambient pressure compresses the exhaust against the spike. The plug-cluster aerospike engine puts out 90,000 pounds-force (400 kN) of thrust. In July 2014 Firefly Space Systems announced its planned Alpha launcher that uses an aerospike engine for its first stage. , Instead of firing the exhaust out of a small hole in the middle of a bell, an aerospike engine avoids this random distribution by firing along the outside edge of a wedge-shaped protrusion, the "spike", which serves the same function as a traditional engine bell. The Spike S-512 is a projected supersonic business jet, designed by Spike Aerospace, an American aerospace manufacturer firm based in Boston, Massachusetts. The two rockets were solid-fuel powered and fitted with non-truncated toroidal aerospike nozzles. The single-engine tests were a success, but the program was halted before the testing for the two-engine setup could be completed. This work on aerospike engines continues; Prospector-10, a ten-chamber aerospike engine, was test-fired June 25, 2008.. ARCA Space Corporation has announced its linear aerospike engine is ready to start ground tests as the company moves towards installing the engine in its Demonstrator 3 rocket. Spike Aerospace says it has been working with two engine makers and is in early discussions with a third for potential powerplant options for its S-512 supersonic jet. They announced a flight for August 2017. Salaries, reviews, and more - all posted by employees working at Spike Aerospace. , The disadvantages of aerospikes seem to be extra weight for the spike. Spike Aerospace’s vision to reintroduce supersonic flight that is quieter, sustainable and efficient is game changing. Rocketdyne conducted a lengthy series of tests in the 1960s on various designs. It gives no overall thrust, but this part of the nozzle also doesn't lose thrust by forming a partial vacuum. Using material science, avionics, airframe, and engine technologies, the company aims to build The Spike S-512 Supersonic Jet, a business jet designed to fly at Mach 1.6, 450 mph faster than other civilian jets. Spike Aerospace is looking for low to medium bypass ratio (BPR) engines with approximately 20,000 lbs of sea-level thrust. Add a spacious bedroom, dining room, conference room or lavish bathroom with shower. Superior aircraft strength made possible by eliminating traditional windows allows the S-512 to offer unprecedented noise reduction for smooth, relaxing supersonic flights. The Spike S-512 Supersonic Business Jet is a stunningly elegant and innovative business jet that sweeps passengers to their destinations in half the time it takes on other jets. Full cruising speed of Mach 1.6 without producing a loud, disturbing sonic boom on the ground. The rocket is designed to send up to 100 kg into low-Earth orbit, at a price of US$1 million per launch. In March 2017 ARCA Space Corporation announced their intention to build a single-stage-to-orbit rocket, named Haas 2CA, using a linear aerospike engine. The spike forms one side of a "virtual" bell, with the other side being formed by the outside air. An artist’s conception shows Spike Aerospace’s S-512 supersonic jet in flight. It uses carbon composite materials and uses the same basic design for both stages. This occurs on the ground from cross winds and in flight with aircraft pitch and … However, no such engine is in commercial production, although some large-scale aerospikes are in testing phases.. The exhaust, a high-temperature mix of gases, has an effectively random momentum distribution (i.e., the exhaust pushes in any direction it can). In the linear aerospike the spike consists of a tapered wedge-shaped plate, with exhaust exiting on either side at the "thick" end. Boeing … Rocketdyne conducted a lengthy series of tests in the 1960s on various designs. Aerospikes work relatively poorly between Mach 1–3, where the airflow around the vehicle has reduced the pressure, thus reducing the thrust.. Spike Aerospace, a Boston startup that is developing a new supersonic business jet, is in discussions with Washington state and Puget Sound-area aerospace suppliers to open a … A vehicle with an aerospike engine uses 25–30% less[definition needed] fuel at low altitudes, where most missions have the greatest need for thrust. For the Spike S-512 Quiet Supersonic Jet, modifications to those engines would likely need to be made. If the exhaust is allowed to escape in this form, only a small part of the flow will be moving in the correct direction and thus contribute to forward thrust. The Spike S-512. This design has the advantage of being stackable, allowing several smaller engines to be placed in a row to make one larger engine while augmenting steering performance with the use of individual engine throttle control.  In September 2017, ARCA announced that, after being delayed, their linear aerospike engine was ready to perform ground tests and flight tests on a Demonstrator3 rocket.

Major components of a turbojet including references to turbofans, turboprops and turboshafts: Cold section: Air intake (inlet) — For subsonic aircraft, the inlet is a duct which is required to ensure smooth airflow into the engine despite air approaching the inlet from directions other than straight ahead. The Multiplex Digital Screens provide the right ambiance for every occasion. Aerospike engines have been studied for a number of years and are the baseline engines for many single-stage-to-orbit (SSTO) designs and were also a strong contender for the Space Shuttle main engine. Ambient air pressure also imparts a small pressure against the exhaust, helping to keep it moving in the "right" direction as it exits the engine. Best Cities for Jobs 2020 NEW! See what employees say it's like to work at Spike Aerospace. , On December 20, 2019, ARCA tested the LAS 25DA aerospike steam rocket engine for the Launch Assist System. In the latest design, seven RS-2200s producing 542,000 pounds-force (2,410 kN) each would boost the VentureStar into low earth orbit. However, frequently, a full-length plug nozzle is now called an aerospike. Most modern engines have high BPR to improve efficiency and reduce engine noise near airport communities. These individuals will be working on the Spike S-512 Quiet Supersonic Jet with our senior aircraft design team, as well as aerodynamic, structural, and systems engineers. , Rocketstar planned to launch its 3D-printed aerospike rocket to an altitude of 50 miles in February 2019. , Firefly Alpha 1.0 was designed to carry payloads of up to 400 kilograms (880 lb). A prototype of the aircraft’s 76,000-pound-thrust H-Magjet 5500 hybrid turbofan ramjet engines could be tested by year-end. The RS-2200 was to power the VentureStar single-stage-to-orbit vehicle. DUBAI (Reuters) - Spike Aerospace Inc has signed up its first orders and is close to selecting an engine for the $125 million supersonic business jet it is developing, its president said on Monday. However, the Spike S-512 was designed to fly at speeds above Mach 1.6 or around 1,200 miles per hour (mph). The purpose of any engine bell is to direct the exhaust of a rocket engine in one direction, generating thrust in the opposite direction. This rocket was designed to test several components of their Haas 2CA at lower cost. Later models of these engines were based on their highly reliable J-2 engine machinery and provided the same sort of thrust levels as the conventional engines they were based on; 200,000 lbf (890 kN) in the J-2T-200k, and 250,000 lbf (1.1 MN) in the J-2T-250k (the T refers to the toroidal combustion chamber). The S-512 can be configured to reflect your style, success and vision for the future. These individuals will be working on the Spike S-512 Quiet Supersonic Jet with our senior aircraft design team, as well as aerodynamic, structural, and systems engineers. 15th January 2021. The aerospike nozzles and solid rocket motors were developed and built by the rocket motor division of Cesaroni Technology Incorporated, north of Toronto, Ontario. Done right, there will be a significant demand for this aircraft. Spike Aerospace is developing the world's first supersonic business jet that will save passengers 50% flying time. The Spike S-512 is an ultra quiet supersonic business jet that cut flights times in half without creating a loud sonic boom. This aircraft will have a fuel capacity that can be used for 40,000lbs and a maximum range of 4,000nm. An introduction to the aerospike rocket engine.  They later announced that their Executor Aerospike engine would produce 50,500 pounds-force (225 kN) of thrust at sea level and 73,800 pounds-force (328 kN) of thrust in a vacuum. The engine's name of “T-1 Toroidal Aerospike “Dart” Liquid Fuel Engine” is derived from its real world inspiration—the toroidal aerospike engine flown on the Dryden Aerospike Rocket Test. After more development and considerable testing, this project was cancelled when the X-33's composite fuel tanks repeatedly failed. A new company, Firefly Aerospace, has replaced the aerospike engine with a conventional engine in the Alpha 2.0 design. Since this exhaust begins traveling in the "wrong" direction (i.e., outward from the main exhaust plume), the efficiency of the engine is reduced as the rocket travels because this escaping exhaust is no longer contributing to the thrust of the engine. I have heartily recommended Spike to many people who have asked me about my experiences and I will happily continue to do so in the future. For the Spike Supersonic Jet, modifications to those engines would likely need to made. Spike Aerospace of Boston is self-funding a design incorporating a pair of unspecified 20,000-pounds-thrust engines.
