Written by Sarah Stodder | Published on August 11, “specks of comet stuff ,” as NASA recently termed them in a press release, meet. Meteor is an active radar guided beyond-visual-range air-to-air missile (BVRAAM ) developed It entered service in the Swedish air force in April , with the SwAF as the first operator of the missile due to most Meteor was selected in competition to meet the UK's Staff Requirement (Air) (SR(A)), for a Future.

The warhead is a structural component of the missile. TDR propulsion provides a long range, a high average speed, a wide operational envelope from sea level to high altitude, a flexible mission envelope via active variable thrust control, relatively simple design, and logistics similar to those of conventional solid-fuel rocket motors. The PSS forms a structural component of the missile, the gas generator and ramcombustor having steel cases.

The propulsion control unit electronics are mounted in the port intake fairing, ahead of the fin actuation subsystem. The solid propellant nozzleless booster is integrated within the ramcombustor and accelerates the missile to a velocity where the TDR can take over.

The air intakes and the port covers which seal the intake diffusors from the ramcombustor remain closed during the boost phase.

The intakes are manufactured from titanium. The gas generator is ignited by the hot gases from the booster combustion which flow through the open control valve.

The gas generator contains an oxygen deficient composite solid propellant which produces a hot, fuel-rich gas which auto-ignites in the air which has been decelerated and compressed by the intakes.

The high energy boron -loaded propellant provides a roughly threefold increase in specific impulse compared to conventional solid rocket motors.

Reducing the throat area increases the pressure in the gas generator which increases the propellant burn rate, increasing the fuel mass flow into the ramcombustor. The mass flow can be varied continuously over a ratio greater than The Meteor PSS will be able to cope with high incidence and limited sideslip angles during manoeuvres but not negative incidences or large amounts of sideslip.

Meteor's control principles are intended to allow high turn rates while maintaining intake and propulsion performance. The FAS is mounted at the rear of the intake fairings. The design of the FAS is complicated by the linkages required between the actuator in the faring and the body mounted fins. Datalink[ edit ] Meteor will be 'network-enabled'. A datalink will allow the launch aircraft to provide mid-course target updates or retargeting if required, including data from offboard third parties.

The datalink electronics are mounted in the starboard intake fairing, ahead of the FAS. The antenna is mounted in the rear of the fairing. On 19 November Bayern-Chemie completed the latest in a series of tests designed to assess the attenuation of signals by the boron rich exhaust plume of the TDR, a concern highlighted by opponents of this form of ramjet propulsion.

Tests were conducted with signals transmitted through the plume at various angles. The initial results suggested that the attenuation was much less than expected. Mid-course guidance is provided by the fighter though not necessarily the one that launched the missile until the active seeker acquires the target; the missile then becomes autonomous for the terminal engagement phase.

Planes fitted with high off bore sight radars can turn away at higher angles and maintain mid-course updates. Alternatively, the Meteor can be fired without using mid-course update, hampering its chances to find a target, but allowing the Rafale to immediately turn away similar to " Fire and forget " AASMMICA or Exocet missile types.

This makes it kinematically less likely that the engaged aircraft can hit the Rafale fighter with a missile of comparable capabilities unless the Meteor missile was launched at much shorter range than its engagement range limit. The missiles will be stored in dedicated containers when not in use.

The Meteor is intended to have an airborne carriage life of 1, hours before any maintenance is required.

France is funding It is estimated that over companies across Europe will be involved. Work will be allocated by MBDA to its risk-sharing partners on an "earned value basis" under which work is placed according to best commercial value, taking into account technical excellence, but with a view to aligning "broadly" with the share of development funding provided by each nation. The programme will initially create and sustain jobs across Europe, in the UK, but successful exports could double these figures.

The first firing, from Gripen, was expected in with an in service date of August In December the Spanish government authorized the procurement of Meteor missiles and their corresponding support equipment. To demonstrate control of the asymmetric airframe. There was concern that the intake air flow would be disrupted during manoeuvres resulting in a loss of propulsion performance or even control. The asymmetric configuration also poses unique control problems.

Achievement of this milestone was to be demonstrated using computer models validated from the Air Launched Demonstrator ALD trials results. To demonstrate transfer alignment of the missile's inertial measurement system. This process ensures that the missile knows where it is at launch.

Good knowledge of initial position is essential to accurate navigation, particularly for long range engagements. By the summer of manufacture had commenced of a full-scale model for aircraft fit checks as well as sub-scale models for wind tunnel tests scheduled for the autumn.

What is a Meteor?

Following extensive pre-contract wind tunnel testing and MBDA's growing experience with guidance and control technologies for wingless configurations, such as ASRAAMa wingless design was believed to offer the best solution to meeting the performance requirements. The control fins were also redesigned so that all four fins were now identical. In December MBDA and Saab Bofors Dynamics signed an enabling contract worth m kronor covering programme management, system level participation, participation in the development of seeker, guidance, and autopilot algorithms, development of missile software, development of test equipment, system proving activities, and the TBUS.

These tests successfully demonstrated the air intake operation and validated the modelled aerodynamic characteristics, confirming the configuration for the first flight trials.

These were planned to begin with a 'part-firing' before the French summer holidays to be followed by two full-scale firings later in the year. These would comprise a full end-to-end demonstration of the complete propulsion system at representative supersonic free flight conditions as a risk reduction exercise for the ALD firings, scheduled for the last quarter of During these tests a full-scale missile model fitted with a live PSS would be mounted on a moveable strut in the wind tunnel, allowing a series of incidence and sideslip manoeuvres to be conducted over the full duration of the PSS operation.

The tests would demonstrate operation of the air intakes, the transition from boost to sustain propulsion, control of the sustain motor thrust, and provide data on the aerodynamic characteristics. The EDG is an instrumented missile representing all the dynamic properties of an operational missile in terms of size, weight, and aerodynamic shape. The trials were designed to measure the shock and vibration levels associated with the severe carrier operational environment.

Around twenty catapult launches and full deck arrests were undertaken, along with a number of touch and go landings on the fightdeck to provide a fully comprehensive handling test of the aircraft while fitted with Meteor.

The trials went so well that they were concluded a day earlier than planned. This was the first in-flight trial of two-way communication between the missile and aircraft and was an important step in clearing the aircraft and missile for the ALD firings which had slipped into Springdue to the lack of winter daylight hours at the Vidsel Test Range in northern Sweden.

In a separate air-carry trial a Eurofighter of No. The missile was launched from the port underwing MML, separating safely from the launch aircraft as the integrated booster accelerated the missile to over Mach 2. The missile continued under boost impulse, gradually decelerating until broken up, on command from the ground. Despite this problem telemetry was gathered throughout the full duration of the flight. The missile debris was recovered and the air intakes were found to be still closed.

Following modification a repeat of the first trial took place on 20 May and was a complete success. During the sustain phase the missile carried out a series of pre-programmed manoeuvres, under autopilot control, representative of the mid-course and endgame phases of an engagement.

The flight lasted just under a minute and ended again with the successful operation of the break-up system which destroyed the missile within the range boundary.

The first trial of a flight standard functional seeker was carried out on 30 June The SDG missile has no propulsion system or warhead but contains operational missile subsystems and telemetry systems. The flight lasted approximately 1. These data will be used in support of the third Key Milestone. This marked the start of a two-year seeker development programme which will conclude with the first guided firing, currently scheduled for from Gripen.

The comet visits our part of the solar system every years. In Novemberit brightened to 5th magnitude and was visible without optical aid only from the darkest sites. During its next close passage init will shine slightly brighter than 1st magnitude. By the way, astronomers call this particular shower the Perseids because if you trace all the meteor trails backward, they meet within the boundaries of the constellation Perseus the Hero.

The point of origin the direction in space toward which Earth is heading is called the radiant. He took a 7-second exposure at ISO Larry Kuhn Perseids Forecast Scientists who study meteor showers predict the Perseids will peak between 4 p.

EDT August 12 and 4 a. Based on these times, meteor watchers in the United States who can spend the night outdoors should begin observing at the end of astronomical twilight on the 12th and watch the sky until dawn. This year, the shower will be active between about July 17 and August Early in the evening on August 12, set up a lawn chair preferably one that reclinesface east, and look a third to half of the way up in the sky.

Bright meteors that travel near the top of the atmosphere and leave long trails are more common at this time.

Glancing around is OK. How many Perseids will you see? Meteor counters use a quantity called the zenithal hourly rate ZHR.

This is the number of meteors visible per hour for an observer under a dark sky with no scattered light and with the radiant positioned directly overhead. The ZHR for the Perseids is This year, with the Moon out of the sky, you can expect to count between 80 and 90 meteors per hour from a dark site — a terrific rate! Be comfortable, have fun, and get ready for some oohs and aahs.
