The SOCATA TBM (now Daher TBM) is a family of high performance single-engine turboprop light business and utility aircraft manufactured by Daher. It was originally collaboratively developed between the American Mooney Airplane Company and French light aircraft manufacturer SOCATA.

The design of the TBM family originates from the Mooney 301, a comparatively low-powered and smaller prototype Mooney developed in the early 1980s. Following Mooney's acquisition by French owners, Mooney and SOCATA held a series of in-depth discussions on the potential for co-developing a new enlarged turboprop design derived from the earlier 301; these resulted in the formation of a joint venture for the purpose of developing and manufacturing the envisioned aircraft, which was designated as the TBM 700. From the onset, emphasis was placed upon the design's speed, altitude, and reliability. Upon its entry onto the market in 1990, it held the distinction of being the first high-performance single-engine passenger/cargo aircraft to enter production.[3]

Shortly after launch, the TBM 700 was a market success, which quickly led to the production of multiple variants and improved models, often incorporating more powerful engines and new avionics, amongst other features. The TBM 850 is the production name assigned to the TBM 700N, an improved version of the aircraft powered by a single Pratt & Whitney PT6A-66D. In March 2014, an aerodynamically refined version of the TBM 700N, marketed as the TBM 900, was made available.[4]

Development[edit]

Origins[edit]

In the early 1980s, the Mooney Airplane Company of Kerrville, Texas, designed a six-seat pressurised light aircraft, powered by a single 360 hp (268 kW) piston engine, which they designated the Mooney 301. On 7 April 1983, the prototype 301 conducted its maiden flight.[5] During 1985, the Mooney Aircraft Company was acquired by new French owners, who promptly took an interest in the further development of the fledgling 301.[6]:441 Coinciding with the company's acquisition, French light aircraft manufacturer SOCATA, who had identified a vacant market position for a purpose-built optimised single-engine aircraft capable of fast personal transport and light cargo duties, identified the piston-powered 301 as a potential starting point to satisfy this niche.[3]

Accordingly, talks soon commenced between Mooney and SOCATA on the subject of producing a turboprop-powered derivative of the 301.[5] The product that emerged from these discussions was a new design, referred to as the TBM 700, which was considerably heavier than the original 301 while provisioned with more than twice the available power. The prefix of the designation, TBM, originated from the initials "TB", which stands for Tarbes, the French city in which SOCATA is located, while the "M" stands for Mooney.[5] At the time of its conception, while several aviation companies had studied or were otherwise considering the development of such an aircraft, the envisioned TBM 700 was the first high-performance single-engine passenger/cargo aircraft to enter production. From the onset, key performance criteria were established for the design, demanding a high level of reliability while also being capable of an unequalled speed/altitude combination amongst the TBM 700 other single-engined peers.[3]

A TBM 700

Consequently, during June 1987, a joint venture, named TBM International, was established with the aim of completing development of the TBM 700 design and to perform the manufacture of the new aircraft; the ownership of the joint venture was divided between Mooney and SOCATA's parent company Aérospatiale.[5][6]:135 A pair of separate production lines for the TBM 700 were planned, one located at Mooney's facility in Kerrville, Texas, which was intended to cater to the American market, and the other based at SOCATA's factory in Tarbes, which was set to produce aircraft for customers throughout the rest of the world.[3] However, during the late 1980s and early 1990s, Mooney was afflicted by persistent fiscal shortfalls; consequently, in May 1991, Mooney chose to withdraw from participation in the joint venture, leaving SOCATA as the primary company involved in the programme.[5]

On 14 July 1988, the first TBM 700 prototype conducted the type's maiden flight.[6]:135[3] Flight testing proved that virtually all of the established goals of the design had been achieved, leading to quick progress towards production. On 31 January 1990, type certification was received from French authorities; it was followed by the awarding of US Federal Aviation Administration (FAA) certification on 28 August 1990.[5] During early 1990, the first delivery of a TBM 700 occurred; the first production batch of 50 aircraft were sold out almost instantly. Early feedback received from operators and pilots was typically positive about the capabilities of the new aircraft, often praising its speed and generous power margins amongst other attributes.[3]

Further development[edit]

According to aerospace publication Flying, while the TBM 700 had rapidly proved popular on the market and a good aircraft on its own merits, the services and support facilities SOCATA provided for the aircraft were an initial point of weakness.[3] Early on, customers were often faced with lengthy delays in acquiring spare parts and other services; negative feedback on the after sales support for the TBM 700 has been attributed as the cause of a downturn in sales during the 1990s. SOCATA, recognising the critical importance of an effective support infrastructure, decided to invest heavily in improving worldwide support for the type; instead of being solely reliant upon third parties and partnership arrangements with other companies, the firm developed their own facilities.[3] SOCATA opened its own service center in Florida, as well as establishing a network of distributors capable of both sales and services for the TBM 700. Consequently, during the late 1990s, sales of the type within the North American market rose dramatically.[3]

Early on, the TBM 700 was available in several different configurations and models. The introduction of the TBM 700C2, which increased the maximum takeoff weight from 6,578 to 7,394 lb (2,984 to 3,354 kg), enabled operators to fly with both fully laden fuel tanks and maximum cabin occupancy instead of compromising between the two due to weight restrictions. The modifications made upon this model included the addition of a baggage compartment aft of the rear pressure bulkhead, the strengthening of the wing and landing gear, and seat crashworthiness certification for up to 20 G to accommodate for an elevated stall speed at higher weights. Around the same time, SOCATA decided to re-design the interior of the aircraft, both in terms of the fittings and finish, along with the adoption of a new integrated environmental control system, to improve passenger comfort levels.[3]

The TBM 850 is the production name for the TBM 700N, an improved version of the aircraft powered by a single Pratt & Whitney PT6A-66D engine, which is flat rated at 850 shp (634 kW). The TBM 850 is limited to 700 shp (522 kW) for takeoff and landing; however, during cruise flight, the engine power can be increased to 850 shp (634 kW); this extra power provides the aircraft with a higher cruising speed than the TBM 700 models, especially at high altitudes (due to the flat-rating). The outside appearance of the TBM 850 has remained similar as that of the standard TBM 700. The TBM 850 has a typical range of 1,520 nautical miles (2,820 km). Beginning with the 2008 model, the TBM 850 has been equipped with the Garmin G1000 integrated flight deck as standard equipment.[7]

In 2014, an improved version of the aircraft, marketed as the TBM 900 was introduced, featuring 26 individual modifications, including the adoption of in-house-designed winglets, a redesigned air intake and the fitting of a five-blade Hartzell-built propeller, orientated around delivering improved aerodynamics and performance.[8] The adoption of a sharp strake, located forward and beneath the leading edge of the left wing, also provides for improved stall characteristics over the earlier TBM variants. According to aircraft publication Aviation Week, various subtle exterior changes were made for drag reduction purposes, including the addition of inner main landing gear doors, the re-contouring of the tail cone and of the engine nacelle.[9]

In comparison with the TBM 850, the TBM 900 is around 14 kn (26 km/h) faster in cruise flight, uses less fuel, requires less runway length, climbs faster, and produces noticeably less interior and exterior noise alike.[9] This is partially due to the elimination of the 700 shp (522 kW) limitation for takeoff present on previous TBM models; all 850 shp (634 kW) of the PT6A-66D engine is normally available. In combination with a more efficient air inlet, which boosted the available torque and ram recovery, and reshaped exhaust stacks, which increased thrust output, makes the plane faster. According to Aviation Week, due to its greater speed, the TBM 900 can more effectively compete against light jets. They observed that it is faster on a 600 nmi (1,100 km) mission, and burns 26 per cent less fuel than the Cessna Citation Mustang.[9]

At the June 2018 Eurosatory, an ISR configuration with underwing hardpoints and electrical connections for sensors and aerial photography was offered for defense, security, medical evacuation and transport missions. Competing with heavier aircraft and MALE UAVs, it benefits from its short field performance and speed, offers six hours of surveillance and can be reconfigured for other duties. It was validated with a 110-pound (50-kg) camera and a multi-sensor optronics retractable turret, SAR/ground MTI radar, communication interception system, and secure transmission with a quick-change console for tactical situation monitoring.[10]

In March 2019, Daher introduced the $4.13 million TBM 940 with autothrottle and automatic deicing, to be certified for the April AERO Friedrichshafen.[11]

EcoPulse demonstrator[edit]

At the June 2019 Paris Air Show, Daher, Airbus and Safran teamed up to develop the TBM-based EcoPulse demonstrator for a hybrid electric aircraft. The project is kick-started by the French Civil Aviation Research Council (CORAC) with support from the French DGAC. Safran will provide the distributed hybrid propulsion system: turbogenerator, electric power management system and electric motors and propellers. Airbus will install the batteries and optimize the aerodynamics, and Daher will install components and systems, and will be responsible for the flight testing and overall analysis.[12]

Half of the €22 million ($25 million) demonstration funded by the DGAC, the maiden flight is scheduled for the summer of 2022 before a hypothetical 2025-30 certification. The aircraft’s existing engine will be supplemented by six 45 kW (60 hp) safran electric motor on the wing fed by a 100 kW (130 hp) APU or batteries. Similar to the NASA X-57 Maxwell, the distributed propulsion reduces wingtip vortices and add low speed lift by blowing the wing, enabling a smaller, lower drag wing.[13] The high voltages required, over 500 volts, is a new challenge in aviation and special cables and protection were developed by Safran. After a year of testing, a follow-on commuter aircraft might be built by Daher.[14]

Design[edit]

A TBM 900 just prior to landing, November 2015

The SOCATA TBM is a single-engined turboprop-powered low-wing monoplane, capable of seating a maximum of seven people. It is composed mainly of aluminium and steel construction, but with the tail surfaces built of Nomex honeycomb. The wing features a very effective Fowler flap, comprising 80 per cent of the trailing edge's span, for the purpose of lowering the aircraft's stall speed. The TBM 700 is outfitted with a retractable tricycle landing gear arrangement, newer models feature stronger main landing gear wheels and tougher tyres.[3][5][15] The TBM 900 model features automatic torque limiting for “set and forget” power management, which is of particularly use during takeoffs; according to Aviation Week, while this function does reduce the high workload associated with managing the PT6A engine, it is not as capable as a full FADEC arrangement.[9]

The cockpit design of the TBM strives to be user-friendly and as uncomplicated to operate as possible. For pilot convenience, an automatic fuel selector automatically switches between fuel tanks periodically to effortlessly maintain fuel balance throughout flight; manual selection of fuel tanks is also possible, which remains overseen by a low fuel warning system.[3] The ice protection system is as automated as possible, the windshield being electrically heated, the air inlet being kept warm by engine exhaust and the de-ice boots automatically cycling once activated. The electrically actuated flaps are monitored by a sophisticated split-flap protection system to prevent asymmetric deployment.[3] An onboard air data computer calculates various values to support the pilot, such as the aircraft's true air speed, wind, and power advisory notices based upon current external temperature and altitude.[3]

The Pratt & Whitney Canada PT6A-64 engine, providing up to 700 shp (522 kW).[5][15] According to Flying Magazine, the PT6A-64 engine is "the secret to the TBM 700's performance.[3] At sea level, the engine is capable of generating a maximum 1,583 shp (1,180 kW), which is intentionally limited to 700 shp (522 kW) on early TBM models; the limit allows the aircraft to maintain 700 shp (522 kW) up to 25,000 ft (7,620 m) on a typical day. Engine reliability and expected lifespan are also enhanced by the limitation.[3] While the typical engine overhaul life is set as 3,000 flight hours between overhauls, on-condition servicing can also be performed due to various engine parameters being automatically recorded by the engine trend monitoring (ETM) system. Data from the ETM can be reviewed by the engine manufacturer to determine the level of wear and therefore the need for inspection or overhaul. The ETM, which is connected to the aircraft's air data computer, also provides information to enable easy power management by the pilot.[3]

The cockpit of the TBM seats a pair of flying crew. According to Flying Magazine, even in the standard configuration, the cockpit is provided with a generous suite of avionics and equipment. It features an electronic flight instrument system (EFIS), traffic collision avoidance system (TCAS), terrain awareness and warning system (TAWS), weather radar, lightning detection, dual Garmin GNS 530 navigation/communication systems, Bose headsets, dual transponders, dual compasses, and full cockpit instrumentation for both positions. Pilots can enter the cockpit either from the main cabin or via a small pilot's door on the left hand side, forward of the wing; in a cargo configuration, the pilot's door eliminates the need to clamber over the cargo payload.[3] The pilot's door is an optional extra, and is not installed upon all aircraft. From the TBM 700B onwards, an enlarged cabin entry door was introduced, which later became standard upon subsequent models.[3]

The TBM 900 model features several ergonomic improvements within the cockpit, increasing both simplicity and automation.[9] A new single power lever integrates the power, propeller and condition lever controls. Various switches and controls, such as some formerly present upon the overhead panel, have been eliminated.[9] The electrical system is powered by a single main generator, which is supplemented by a belt-driven alternator.[3] On the TBM 900, electrical load distribution changes enable the Garmin G1000 glass cockpit to power up in sync with the switch-on of the battery with little battery drain. The G1000 also has upgraded displays, including an ISA temperature deviation indication, integrated weather radar and MFD map, and automatic landing field elevation inputs to the pressurization controller.[9]

In a passenger configuration, the pressurised cabin of the TBM is typically fitted with highly finished interiors, often featuring luxury materials such as high quality leathers and wood veneers. The seats are certified for their crashworthiness for up to 20 G. From the TBM 850 onwards, a combined air conditioner/environmental control system was integrated into the cabin, being simpler and requiring less adjustment than the prior arrangement.[3] At cruise altitudes, the cabin of the TBM 900 is noticeably quieter than its predecessors; the reduction is due to the adoption of a new five-bladed propeller and the reduction of vibration levels via greater isolation between the engine and the airframe.[9] Later built models are equipped with winglets, which were developed by SOCATA primarily to reduce drag when flown at high angles of attack, such as during takeoffs, as well as to enhance the aircraft's aesthetics.[9] The TBM 900 saw the adoption of a new five-bladed propeller, specially optimised by Hartzell based upon airflow simulations conducted of the TBM's forward section. According to SOCATA, Hartzell's selection over a similar advanced counterpart from MT-Propeller was made due to the former raising the cruise speed by around 3 to 5 kn (5.5 to 9 km/h).[9]

In October 2017 Daher advertised that the design had a 60 US gal (230 l) fuel burn and US$213–228 maintenance cost per flight hour.[16]
