The NASA M2-F1 was a lightweight, unpowered prototype aircraft, developed to flight test the wingless lifting body concept. It looked like a "flying bathtub," and was designated the M2-F1, the "M" referring to "manned" and "F" referring to "flight" version. In 1962, NASA Dryden management approved a program to build a lightweight, unpowered lifting body prototype. It featured a plywood shell placed over a tubular steel frame crafted at Dryden. Construction was completed in 1963.

Development



The lifting-body concept originated in the mid-1950s at the National Advisory Committee for Aeronautics' Ames Aeronautical Laboratory, Mountain View, California. By February 1962, a series of possible shapes had been developed, and R. Dale Reed was working to gain support for a research vehicle.



The construction of the M2-F1 was a joint effort by Dryden and a local glider manufacturer, the Briegleb Glider Company. The budget was US$30,000. NASA craftsmen and engineers built the tubular steel interior frame. Its mahogany plywood shell was hand-made by Gus Briegleb and company. Ernie Lowder, a NASA craftsman who had worked on Howard Hughes' H-4 Hercules (or Spruce Goose), was assigned to help Briegleb.



Final assembly of the remaining components (including aluminum tail surfaces, push rod controls, and landing gear from a Cessna 150, which was later replaced by Cessna 180 landing gear[2]) was done at the NASA facility.



The wingless, lifting body aircraft design was initially conceived as a means of landing a spacecraft horizontally after atmospheric reentry. The absence of wings would make the extreme heat of re-entry less damaging to the vehicle. Rather than using a ballistic reentry trajectory like a Command Module, very limited in manoeuvering range, a lifting body vehicle had a landing footprint the size of California.[3]



Tow testing

The M2-F1 and its 1963 Pontiac convertible tow vehicle

The first flight tests of the M2-F1 were at Rogers Dry Lake, at the end of a tow rope attached to a Pontiac Catalina convertible. On April 5, 1963 test pilot Milt Thompson lifted the M2-F1's nose off the ground for the first time on-tow.[2] Speed was 86 miles per hour (138 km/h) . The little craft seemed to bounce uncontrollably back and forth on the main landing gear, and stopped when he lowered the nose to the ground. He tried again, but each time with the same results. He felt it was a landing gear problem that could have caused the aircraft to roll on its back if he had lifted the main gear off the ground.[citation needed]



After looking at movies of the tests, it was decided that the bouncing was probably caused by unwanted rudder movements. Flight control system number two was replaced in favor of number one, and it never bounced again.[citation needed]



It was found that the car used to tow the aircraft was not powerful enough to entirely lift the M2-F1 off the ground, so the FRC arranged to have the tow car hot-rodded by Bill Straub, a conversion that tuned the engine for increased power, added a rollbar, and turned the front passenger seat to face aft so the passenger could observe the aircraft. This proved successful and tow tests continued.[2]



Speeds on tow inched up to 110 miles per hour (180 km/h) , which allowed Thompson to climb to about 20 feet (6.1 m) , then glide for about 20 seconds after releasing the line. That was the most that could be expected during an auto tow.

These initial tests produced enough flight data about the M2-F1 to proceed with flights behind a U.S. Navy C-47[2] tow plane at greater altitudes.



Flight testing



A NASA C-47 was used for all of the aero tows. The first was on August 16, 1963. The M2-F1 had recently been equipped with an ejection seat and small rockets - referred to by the test team as "instant L/D"[2] - in the tail to extend the landing flare for about 5 seconds if needed, and Thompson prepared for the flight with a few more tows behind the Pontiac.



Forward visibility in the M2-F1 was very limited on tow, requiring Thompson to fly about 20 feet (6.1 m) higher than the C-47 so he could see the plane through the nose window. Towing speed was about 100 miles per hour (160 km/h) .



The C-47 took the craft to an altitude of 12,000 feet (3,700 m) where free flights back to Rogers Dry Lake began. Pilot for the first series of flights of the M2-F1 was NASA research pilot Milt Thompson. Typical glide flights with the M2-F1 lasted about two minutes and reached speeds of 110 to 120 miles per hour (180 to 190 km/h)



Tow release was at 12,000 feet (3,700 m) The lifting body descended at an average rate of about 3,600 feet-per-minute (1,100 m/min). At 1,000 feet (300 m) above the ground, the nose was lowered to increase speed to about 150 miles per hour (240 km/h) , flare was at 200 feet (61 m) from a 20 degree dive. The landing was smooth, and the lifting body program was on its way.



The M2-F1 was flown until August 16, 1966. It proved the lifting body concept and led the way for subsequent, metal "heavyweight" designs. Chuck Yeager, Bruce Peterson and Don Mallick also flew the M2-F1.



More than 400 ground tows and 77 aircraft tow flights were carried out with the M2-F1. The success of Dryden's M2-F1 program led to NASA's development and construction of two heavyweight lifting bodies based on studies at NASA's Ames and Langley research centers—the Northrop M2-F2 and the Northrop HL-10, both built by the Northrop Corporation, and the U.S. Air Force's X-24 program. The lifting body program also heavily influenced the Space Shuttle program.



The M2-F1 program demonstrated the feasibility of the lifting-body concept for horizontal landings of atmospheric entry vehicles. It also demonstrated a procurement and management concept for prototype flight research vehicles that produced rapid results at very low cost (approximately $US 50,000, excluding salaries of government employees assigned to the project).

Role:  Lifting body Technology Demonstrator

National origin:  United States

Manufacturer:  Northrop
First flight:  12 July 1966

Retired:  10 May 1967

Status:  Rebuilt as M2-F3

Primary user:  NASA

Number built:  1

Developed from:  NASA M2-F1


Variants



Northrop M2-F3



The Northrop M2-F2 was a heavyweight lifting body based on studies at NASA's Ames and Langley research centers. Built by the Northrop Corporation in 1966. The "M" refers to "manned" and "F" refers to "flight" version.



Development



The success of Dryden's M2-F1 program led to NASA's development and construction of two heavyweight lifting bodies based on studies at NASA's Ames and Langley research centers—the M2-F2 and the HL-10, both built by the Northrop Corporation. The "M" refers to "manned" and "F" refers to "flight" version. "HL" comes from "horizontal landing" and 10 is for the tenth lifting body model to be investigated by Langley. (See also NASA Ames Research Center).



The M2-F2 made its first captive flight (attached to the B-52 carrier aircraft throughout the flight) on March 23, 1966.



The first flight of the M2-F2 - which looked much like the "M2-F1" - was on July 12, 1966. Milton O. Thompson was the pilot.



By then, the same B-52 used to air launch the famed X-15 rocket research aircraft was modified to also carry the lifting bodies. Thompson was dropped from the B-52's wing pylon mount at an altitude of 45,000 feet (13,700 m) on that maiden glide flight. He reached a gliding speed of about 450 miles per hour (720 km/h).



Operational history



File:M2-F2 crash.jpg

The crash site of the M2-F2

Before powered flights were undertaken, a series of glide flights were conducted. On May 10, 1967, the sixteenth and last glide flight ended in disaster as the vehicle slammed into the lake bed on landing. With test pilot Bruce Peterson at the controls, the M2-F2 suffered a pilot induced oscillation (PIO) as it neared the lake bed. At the core of this problem was the fact that the wings of the M2-F2 (essentially the body of the aircraft) produced considerably less roll authority than most aircraft. This resulted in less force availible to the pilot to control the aircraft in roll. As a consequence, when Bruce attempted to perform roll maneuvers the response of the vehicle was substantially less than expected, thus lending to a "soft" feel for this control which often leads to PIO in the roll axis. (Source: interview with Bruce Peterson, 1980) The vehicle rolled from side to side in flight as he tried to bring it under control. Peterson recovered, but then observed a rescue helicopter that seemed to pose a collision threat. Distracted, Peterson drifted in a cross-wind to an unmarked area of the lake bed where it was very difficult to judge the height over the ground because of a lack of guidance (the markers provided on the lake bed runway).



Peterson fired the landing rockets to provide additional lift, but he hit the lake bed before the landing gear was fully down and locked. The M2-F2 rolled over six times, coming to rest upside down. Pulled from the vehicle by Jay King and Joseph Huxman, Peterson was rushed to the base hospital, transferred to March Air Force Base and then the UCLA Hospital. He recovered but lost vision in his right eye due to a staphylococcal infection.



Portions of M2-F2 footage including Peterson's spectacular crash landing were used for the 1973 TV movie The Six Million Dollar Man though some shots during the opening credits of the series showed the later HL-10 model, during release from its carrier plane, a modified B-52.



Four pilots flew the M2-F2 on its 16 glide flights. They were Milton O. Thompson (5 flights), Bruce Peterson (3 flights), Don Sorlie (3 flights) and Jerry Gentry (5 flights).



NASA pilots and researchers realized the M2-F2 had lateral control problems, even though it had a stability augmentation control system. When the M2-F2 was rebuilt at Dryden and redesignated the M2-F3, it was modified with an additional third vertical fin -- centered between the tip fins to improve control characteristics.



The M2-F2/F3 was the first of the heavy-weight, entry-configuration lifting bodies. Its successful development as a research test vehicle answered many of the generic questions about these vehicles.

From Wikipedia, the free encyclopedia





M2-F3




Role:  Lifting body Technology Demonstrator

Manufacturer:  Northrop

First flight:  2 June 1970

Retired:  20 December 1972
Status:  Smithsonian

Primary user:  NASA

Developed from:  NASA M2-F1

Northrop M2-F2





The Northrop M2-F3 was a heavyweight lifting body rebuilt from the Northrop M2-F2 after it crashed at the Dryden Flight Research Center in 1967. It was modified with an additional third vertical fin - centered between the tip fins - to improve control characteristics. The "M" refers to "manned" and "F" refers to "flight" version.




Development



Early flight testing of the M2-F1 and M2-F2 lifting body reentry configurations had validated the concept of piloted lifting body reentry from space. When the M2-F2 crashed on May 10, 1967, valuable information had already been obtained and was contributing to new designs.



NASA pilots said the M2-F2 had lateral control problems, so when the M2-F2 was rebuilt at Northrop and redesignated the M2-F3, it was modified with an additional third vertical fin - centered between the tip fins - to improve control characteristics.



After a three-year-long redesign and rebuilding effort, the M2-F3 was ready to fly. The May 1967 crash of the M2-F2 had torn off the left fin and landing gear. It had also damaged the external skin and internal structure. Flight Research Center engineers worked with Ames Research Center and the Air Force in redesigning the vehicle with a center fin to provide greater stability. At first, it seemed that the vehicle had been irreparably damaged, but the original manufacturer, Northrop, did the repair work and returned the redesigned M2-F3 with a center fin for stability to the FRC.



While the M2-F3 was still demanding to fly, the center fin eliminated the high risk of pilot induced oscillation (PIO) that was characteristic of the M2-F2.



Operational history



First flight of the M2-F3, with NASA pilot Bill Dana at the controls, was June 2, 1970. The modified vehicle exhibited much better lateral stability and control characteristics than before, and only three glide flights were necessary before the first powered flight on November 25, 1970. The 100th flight of the heavy-weight lifting bodies was completed on October 5, 1972, with pilot Bill Dana soaring to an altitude of 66,300 feet (20,200 m) and a Mach number of 1.370 (about 904 miles per hour) in the M2-F3. Over its 27 missions, the M2-F3 reached a top speed of 1,064 mph (Mach 1.6). Highest altitude reached by the vehicle was 71,500 feet (20,790 m) on December 20, 1972, the date of its last flight, with NASA pilot John Manke at the controls.

The M2-F3 at the National Air and Space Museum

A reaction control thruster (RCT) system, similar to that on orbiting spacecraft, was also installed to obtain research data about their effectiveness for vehicle control. As the M2-F3's portion of the lifting body program neared an end, it evaluated a rate command augmentation control system, and a side-arm control stick similar to side-arm controllers now used on many modern aircraft.



NASA donated the M2-F3 vehicle to the Smithsonian Institution in December 1973. It is currently hanging in the National Air and Space Museum along with the X-15 aircraft number 1, which was its hangar partner at Dryden from 1965 to 1969.
